OBJECT MODE MODELING


Primitive Mesh Objects

video 2.45
Place 3D cursor by left click; Space 2.45/Shift +A 2.5: Menu: Add -Mesh -….if: define per dialogue box …TAB (-Key) out of edit mode before creaating other object, otherwise part of last object.


Icosphere-Torus

video 2.45
Spacebar (Shift-A in 2.5) Add -Mesh - Icosphere: made out of triangles; Torus: Major and Minor diameter/segments;


Naming Objects

video 2.45
Make habit to name objects: N-Key: Transform Properties panel, change Name, see other transformation options;


2-Dimensional Objects: Plane - Grid - Circle Objects

video 2.45
2-dimensional; Plane: 4 vertices, edges; 1face - Mesh Tools - subdivide in edit mode; Add -Mesh -Grid: define subdivision before; Circle Object: filled or not:
Delete 3 vertices from plane - one single vertex remains: create continuing lines: Ctrl + Left Click to create own shape, edge by edge created by new vertex set via LMB. To close object create until : select 2 vertices to F-Key: closes by edge between selected vertices; ; Or like in video: last vertex very close to first: W Key: Merge vertices at center - removes not needed.


Selecting Objects

video 2.45
Right click - select object (in wireframe klick on edge); A - Key deselects/selects everything in the scene;
B - Key: Box or Border -select: drag box around objects to select with LMB pressed.


Moving Objects

video 2.45
RMB right clik to select, G Key to grab and move it, LMB Left click to place it: Or RMB to select, drag a straight line, then grab mode is applied to object, move it an left click to fix position; ESC if you did not want move; G Key + X,Y,Z to define axis; G + Ctrl : snap to grid; G + Shift: more precision;


Scaling Objects

video 2.45
RMB=right click to select, S-Key - move cursor away from or towards center - scales up and down; Cursor positioned further away from object - more control; S + X,Y,Z scale along only selected axis;
Alternatively via menu: Transform Manipulator ( - switch move-arrows to scale-box on Menu (3D Viewport Footer-menu icons, default:move-arrows)


Rotating Objects

video 2.45
RMB select, R - Key rotate by moving cursor; rotation axis perpendicular to view -> controlable rotation; Alternatively via Menu - Transform Manipultator- switch to circle icon on 3D Viewport footer-menu; Alternatively: LMB pressed - leftclick, hold and draw a Z on the screen - you automatically jump to scale-mode; R + X,Y,Z - define rotation axis;


Transform Properties Panel

video 2.45
N-Key: opens panel to enter precise/numeric position details (rotation, move, scale and name); type number or click arrows;


Global/Local Orientation

video 2.45
Axis widget on left bottom of 3Dviewportwindow shows actual global orientation; If you want to manipulate a rotated object along its own axises: choose local from Drop´down menu (default global) in 3Dviewport footer-menu;


Pivot Points

video 2.45
default Pivot Point: Bounding Box Center, switch in dropdown-iconMenu in 3Dviewportfootermenu; If several selected see, that Median Point (center of all objects) is not the same as Bounding Box Center of the same;


Object Centers

video 2.45
When added, the center point marks the actual center of the object; Object is transformed around this point; when moved in edit mode, the center stays, where it was in object mode; this means rotation around the center point outside of the object then; If: press CENTER NEW button in Button Window - edit Buttons - Mesh Panel; button CENTER: moves Mehs to new center; Center Cursor: moves center to where cursor is (if you WANT to position rotation center outside)


Duplicating Objects

video 2.45
independent copy: RMB select; Shift + D places Duplicate copy right on top in grab mode; to create LINKED copy (changes affect both original and copy): ALT + D


Parenting Objects

video 2.45
last selected object /active object/lighter selection color gets parent to other Ctrl + P;clearing relationship: selecting all objects: Alt + P - select clear parent..; parent to parented objects: General Idea: parent moves child with it, child can move alone;


Deleting Objects

video 2.45
select RMB; X- Key of Delete - Key - select erase selected object; undo by Ctrl + Z


Joining Objects

video;
: Ctrl + J; last active Object is Center; New Object center; no undo;


Separating

video 2.45
only in edit mode, select part of an object; P-Key, choose selected: selected part separate object (switch to object mode and move);
problem if you press P key in object mode; if it happens: Escape Key;


Boolean Menu

video 2.45
2 methods: Menu driven - this (other Modifier); both objects must have enough vertices (!!) - to subdivide: select, wireframe - edit mode: F9 - Mesh tools panel in buttons window, press subdivide button;
W -Key: Boolean Menu, choose intersect: menu driven: always creates new object and keeps originals (grab and move to see result) ; no way to undo except Ctrl + Z / Alt + U (global Undo History);
Difference: Subtracts first selected from second; (the other way round in 2.49 (!))
Material of united, subtracted or differencebooled objects from both objects involved;
Bolean Operation between two objects.


Boolean Modifier

video 2.45
check to have enough vertices for Modifier-Boolean too; (Edit mode - F9 edit buttons in buttons window - subdivide button in mesh tool panel);
N-Key to name objects in Transform Properties panel; RMBselect object you want to apply Modifier to - F9 editbuttons - Modifier Panel - add Modifier - Boolean; choose kind of operation (arrowdropdown), enter name of object to create modification by; Apply: Original gone, only modified object remains, assisting second object remains untouched - Only shapes of "assisting object" are used, modified objects' material only;
Boolean Operation on one object.


Smoothing

video 2.45
prepare rough faced object, F9 edit buttons - Link and Material Panel - click Set Smooth buttton; applies rendering attribute that smoothes out faces; Z-Key wireframe shows that mesh not affected, only rendering smoothed; Set Solid reverses attribute;
In edit mode possible to set smooth only selected part of object;
Edit Mode all selected - Set Smooth: additional: Auto Smooth button in Mesh Panel: allows to define degree upto wich attribution is applied to faces, over set degree definition not set smooth;


Empty Object

video 2.45
Spacebar(2.45 - Shift + A in 2.5) - Add: Empty; point in space; Usually used as parent or part of hook or constraint system to affect other objects;


Text Objects

Spacebar(2.45) / Shift+A(2.5) Add -Text; Backspace to write Text you want - load any font: load in F9 editbuttons-Font Panel - blender marks available purple; To Extrude: Curve and Surface Panel - click arrow besides "Extrude"propertycontrol or bevel edges…;
Text objects are not Mesh Objects; To edit individually: convert: RMBselect, Alt + C - first convert to curve; then Alt+C again, convert to Mesh - now editable in object and edit mode;


Subsurf

video;
Surface subdivision: subdivide + rounded form, edit and object mode, usually edit mode;
Modifier applied via Add Modifier Menu in edit buttons Modifier Panel; Several Controls in Modifier Panel to adjust - Levels; Render Level;
Optimal Draw (see in WireFrame -> Z-key); shows underlying framework; Optimal draw reduces display to editable edges and vertices; (still a cube..)
Wire: Object Buttons F7 - Draw Panel - draws outline wireframe even in object mode;
Editing Cage: Button (!) - not marked circle besides Subsurf Control - when clicked shows verticestriangle; Applies from Editing Cage onto surface of subsurfed object;
Loop Select: ALT + RMB; Knife : K(subdivides crossed edges); Join Triangles; rounding, too many faces for smoothing;
Subsurf for rounding rather than smoothing.

If: black areas when Rendering: Recalculate Normals - their orientation gets mixed (inconsistent) by subsurf process - Select all vertices, Ctrl + N (Only for "Manifold Mesh" - Non-Manifold means there is not one clear out and one inside - to avoid, they leave black lines after recalculating normals and Decimator toll doesn't work)


Weigthed Crease

Weighted edge crease for subdivision surfaces allow to adjust the way Subsurf models geomertry, to give edges/corners a sharp or smooth appearance.
Select edges to adjust - Press Shift + E , drag mouse out of model to sharpen (increase weight), towards to smooth them (decrease weight).
It is also possible to enter direct in Transform Properties Panel . "Crease W" - for complete object.
And finally to activate "Draw Creases" in Mesh Tools More Panel. (Left Bottom)


Symmetrical Modeling Part 1

video 2.45
To see all while modeling on half in order to mirror later:
Front view: Alt + D - create a linked duplicate of half-object - move it on x-axis and rotate (set: ScaleX = -1 via N-Menu)
Model half - see on both;
"example try": - put together by transform snap tool: select magnet/horseshoe in Menu-3Dviewportwindow "closest" in dropdown; Select one half, press G, and Ctrl while moving it towards other half. Selected vertices snap to closest.
Select all, W-key (Special Menu) - Remove Doubles;


Symmetrical Modeling Part 2

video 2.45
Apply Mirror Modifier to original half: Buttons Window, Edit Buttons, Modifier Panel - add Modifier - Mirror - automatically creates Mirrored Half (default on x-plane;
Other controls: Merge Limit: Distance from which vertivces snap together ; Do Clipping button prevents vertices from crossing the Mirror plane;
Another modifier like subsruf allows to control result;


Mirror Menu

video 2.45
Object and Edit Mode; Create duplicate to mirror and move to side; Ctrl + M to open Mirror Menu, choose along which axis;
Same: N-Key (Properties Menu - ScaleX,Y,Z change to -1;
In Edit Mode only M-Key instead of Ctrl+M; More axis-opportunities to Mirror;
To snap together position cursor inbetween vertices to snap, move in grab mode (G-Key) and press Ctrel -Ley: slected vertices will snap to closest:
W-Key Special Menu - choose Remove Doubles;


Decimator Tool

video 2.45
Reduce number of faces on object; Edit Mode, W - Key (Special Menu) - Bevel; (no option to define recursions in 2.49 );
Decimator Tool: Modifier - Object Mode: Modifier Panel - Add Modifier - choose "decimate" - reduce by arrow on the left, see in wireframe how; Apply;


Curve Modifier

video 2.45
Allows to curve Mesh Objects based on associated curve: (Others like curve or text must be converted to Mesh by Alt+C command)
Check to have enough vertices to apply curve; Example cylinder object;
Select edge mode (3DViewportmenubar_icon), box-select edges to subdivide; To create vertices: Loopcut: Press Shift+K (brings up Cut Type Menu: choose "multiple" decide amount); Click and drag with knife across edges - press enter - creates loops. Select newly xcreated loops via Alt + RMB; (UBUNTU: ALT + RMB is occupied by a Window command - System-Preferences-window - change to other Key than Alt;)
Scale selected loops towards center - where you want to bend the cylinder.
Create a NURBS curve - Add/Shift+A-curve-NURBScurve; Edit mode: select endpoints (Buttons window, CurveTools Panel - Endpoint-U button);
Make it quite straight ; Name it via N-Key- Properties Panel
check Center New in Curve and Surface Panel to enable overlapping of center points;
Select Cylinder - Press Shift+S - select cursor to selection;
Then select curve - Shift+S (snap menu) - selection to cursor;
Add Modifier: Curve - type name of curve into object line in Modifier Panel;
Option: select curve and click Curve Strech in curve panel;
But to center it: move to the center;
Edit Mode - select endpoints - move to bend cylinder;
to bend in 3 dimensions - select 3D in Curve and Surface Panel;


Lattice Deformation

video 2.45
Lattice Deformation Tool deforms any object that is its child. Create an object to deform; Spacebar/Shift+A Add - Lattice Object; Scale it a little larger to embrace and position around object. In object mode add subdivisions in Lattice Panel - Edit buttons (Object Mode); Select object to deform, then Lattice and press Ctrl+P - choose Lattice Deformation as Parent; Now in edit mode you can efrom the object by manipulating the Lattice Vertices;
Select deformed object: In Modifier Panel you see "Lattice Parent Deform" - if you press make real the virtual Lattice is added as Modifier to object: you can then apply deformation permamently to object. Now you can delete the Lattice;


Bevelling Tool

video 2.45
Helps to smooth out corners, only on complete object;
Press W-Key (Special Menu) choose Bevel - in 2.34 you can choose number of recursions, from 2.46 on not;


Snap Tool Menu

video 2.45
Shift + S brings up Snap Menu - 5 options - cursor snapping or selection snapping;
For cursor snap to grid, the view reference point is chosen, not the physical grid.
In edit mode you can select middle of an edge by "cursor to selection"
Moving Selection… video shows advantages in modeling


Array Modifier Part 1

vieo 2.45
Place duplicate objects in particular arrangement; Add Array Modifier via Edit Buttons (F9) / Modifier panel, choose from dropdown; Default: "Fixed Count selected in Dropdown; One Duplicate, Relative offset of One (Object Dimension);
Constant Offset: (Relative Off (click)): Grid as scale; duplicate copy is positioned in x,y,z =1 direction 1 Blednder Unitfurther ;
Relative Object: With of cactual offset is unit.
You'll combine them for adjustment.
Dropdown: Kind of Modifier:
Fixed Length: As many duplicates as fixed to listed Length.
Fit to Curve Length: Create Curve and define length, name; Enter Name of Curve to Panel - editable by editing Curve.
Combine Modifier: Apply ("sets in stone") - creates new object, Modifier not visible any more; and add next;


Array Modifier Part 2

video 2.45
Adjust distance: example fence: turn on Constant Offset to adjust in addition to Relative Offset turned on.
Rotation or Scale by Object Offset: 3 "!": all at same point, scale settings, rotation settings:
Object Offset: (usually Empty object) located at exact Pivot Point of object to rotate.
3D Cursor to Rotation Center; Object Center Pivot point to Rotation Point ("Center Cursor" in Mesh Panel Edit Buttons for object), then create empty object at same point.
Check: Rotation settings ( N-Key - see Transform Properties panel) for Object Offset object (Empty) have to be same as for modified object itself;
Same for Scale Settings.
Now add Array Modifier to object, press Object Offset in Miodifier Panel, enter name of Empty; - to create closed rotated object set Relative Offset to Zero.
Video shows several modeling cases: staircase, chain;

In Map Image-Panel (F6) Repeat set on by Default, choose amount of repeats underneath (changes size on object - texture smaller)
Apply Material to second object; Add New Texture or choose from Dropdownarrows; If you choose used texture, make independent: Besides Name number shows how often texture is used in scene, press on number and choose single user - creates independent copy of texture.
F5: Texture, Map Input and Map to Panel:
Map Input panel: says defaut: Projected onto "Flat" - choose shape (Cube, Tube, sphere) here, change preview object display to see preview of result;
sometimes "try" to find best option (example tube - end of video)


BumpMap Texture

video 2.45
simulates texture and relief based on white, black and grey parts of an image;
Light set, in video nurbs circle extruded; Add Material, name.
Texture Buttons F6: add new, choose "Image" in dropdown, load image from harrdrive;
Turn into Bumpmap: Material Buttons (F5); Map To Panel: By default texture applied to Colour: Choose Normal, deselect Colour.
Now mapped to normals instead of colour: creates Relief:
Slider "Normal": raise intensity of Relief.
Bumpmaps work on any mesh, bezier, nurbs object. Does not effect vertices etc.


Multiple Textures

video 2.45
Multiple Textures to single Material; add Material;
F6: Texture Buttons: Add New; dropdown: Image; Load Image - load from harddisk;
Apply as Bumpmap (Change from Color to Normals in Map To Panel);
2nd Texture: Stack of boxes under Texture Button (F6);
Evtl. change name - Select Second Box below, Add New, Choose Image from Dropdown, load from Harddrive - Rename second.
second texture selected - F5 - Material Buttons - Map To Panel - Colour selected, move down colour slider to let first shine through.

Second example (video:) both textures (name!) applied to colour mapping on Map To Panel.
Blender renders Tops down according to list, set transparent via colour slider.
Dropdown Menu over colour slider in Map To Panel: "trial and error"


Noise

video 2.45

displace vertices and meshes based on white, black, grey - value of texture applied to them.
Generally to create landscape.
Subdivide plane strongly; add material - F6:add texture -choose clouds from dropdown.(clouds: built-in blackandwhite texture;
clouds panel: increase noise size; soft noise - hard noise;)
F9 Editing panel - Noise button in Mesh Tools Panel. All vertices selected: click Noise Button. Multiple click - stronger effect on vertices.
Now load Image as texture: once applied, applying via F9 - Noise button on editing buttons adds to noise deformation before (current state of mesh).


Tweaking Materials

video 2.45
more basic controls that effect render: shadow, transparency, wire, shadeless,
Scene: plane, object and 2 lamps for lighting.

Shadow: by default Blender renders shadows; F5: Shaders Panel: Button "Traceable" on: shadows cast, off: no shadows.
Other way: select plane, Button "shadow" in F5 Shaders Panel determines if Objuect accepts-displays shadows cas by other objects.

Transparency: By default set to 1 (solid, bno transparency) - slider in F5 - Material Panel bottom right "A" - for Alpha-channel, set lower than 1: transparency.
To render with transparency: F5 Mirror Transparency Panel: choose z-transparency (or Ray-transparency)

Wire: in F5 MAterial Panel check Button Wire: renders wire of object with material colour.
Shadeless: F5 MAterial Pnle check Button "Shadeless" - renders without any shade, flat colour.
Shader: F5 Shader Panel: emit slider right bottom of panel, increase value: material appears to emitt light.


Transparent Image Texture

video 2.45
png file best, own alpha channel + transparent information - create in gimp or photoshop.
To show transparency in loaded texture: F6 -Image Panel - select Use Alpha Button
Adjust Position: choose projection shape in Map To Panel (here tube though sphere)
MAp Input Panel: adjust size and offset.


UV Texture 1

video 2.45
Regular Textures: Procedural or Image: Add Material, then Add Texture, load Image- applied to mesh coordinates based on choosing kind of object/object coordinates;
More control: UV Mapping
3D mesh unwrapped, all faces laid flat, image file: map to this unwrapped and flattened mesh, pixel by pixel, wrapped back to form, map retains this coordinates pixel by pixel - new coordinates u, v - for width, height; instead of now useless x,y,z.
Usually for complex models, but game engines and googleearth require UV mapping.

UV Texture 2

video 2.45

1.: Make all normals point outwards: Edit mode: Editing buttons - Mesh Tools More panel - click Draw Normals - change size on slider above to see better
Ctrl + N : recalculate normals outside

2.: Open UV Image Editor window via window dropdown menu in right window. Flat grid where faces will be located flat and image will be applied.

3. Change from Object Mode to UV Face Select Mode
Select Face - automtically transferred flat on UV Image Editor.

4.: load Image (in UV Image Editor WindowGot To Image - Open - and load it ).
Displays in Editor - Applied to 3D Viewport dispaly automatically.

Rotate: 3D Viewport: Face (Menu) - Rotate UVs - UV co-ordinates
Resize: Image Editor: A to select all, S to scale -

4. To Render: Material Buttons - Add New Material - click "Tex Face" in Material Panel - tells Blender Texture will be UV Imgae Text Face.

Remove: Unclick Tex Face - Edtiing Buttons: x - delete in MEsh Panel UV Texture.

CAMERA
