Autodesk Mud Box – Paint Texture – Grab Displacement Map

Autodesk Mud Box – Paint Texture – Grab Displacement Map

Il displacement mapping è una tecnica utilizzata nella computer grafica 3D per modellazione degli oggetti. Essa non utilizza gli strumenti standard di modifica, ma si basa sull’elaborazione di immagini in scala di grigio.
Il displacement mapping utilizza lo stesso principio dell'”Images mapping” (mappatura di immagini), ad esempio il “Bump mapping” (rugosità), con la differenza che il displacement interviene direttamente sulla geometria del modello, modificandola. Agendo nella direzione “normale” della superficie, la mappa di displacement provoca uno spostamento in senso positivo dei punti del modello corrispondenti alle zone chiare dell’immagine, e in senso negativo di quelli corrispondenti alle zone scure.

1. Load a 3D Object with UVs map, Subdivide it to increase detail, sculpt the higher level

2. MAIN TOP MENU> UVs & Maps> New Operation…> Displacement Map

Target Models -> yourmodel level 0
Source Models -> yourmodel level highest
Method: Subdivision
Output Options: ‘…’ give it a name and a position into your hard drive

3. ‘Extract’, RIGHT COLUMN> Paint> layers> ‘your-displacement’ Layer appears. Push PGDOWN on the keyboard to see the effect over the lower mesh level 0.

Proietta Displacement Map ricavata dal livello con più dettaglio -> sul livello con meno dettaglio
Method Subdivision perchè si tratta della stessa mesh con suddivisione differente.
Una volta estratta visualizzare il livello più basso della mesh (level 0) per vedere l’effetto finale.
Notare che la texture è stata salvata su disco e applicata al modello in un Paint Layer.

3D Modeling – 3DS Max to Mud Box – Sculpt – Base

3D Modeling – 3DS Max to Mud Box – Sculpt – Base

3DS Max – Export

Start 3DS Max

1. Right Column> Modify> RMB over the Object Name> Editable Poly

Mud Box it is a Subdivision Surface Tool, it works best with Quad Poly and Editable Poly in my opinion.

2. Center the Pivot

3. Center the object at 0,0,0

4. Create UVs inside 3DS Max! The UVs tools of 3DS Max are better than Mud Box

5. MAIN TOP MENU> Export> Export> name.fbx

Mud Box – Import

Start Mud Box

1. MAIN TOP MENU> File> Import…> name.fbx

Mud Box – Create UVs – Paint Textures

BOTTOM WINDOW> Select/Move Tools> Objects> select the Object

1. If you do not have UVs -> MAIN TOP MENU> UVs & Maps> Create UVs…> Replace Existing UVs

BOTTOM WINDOW> Select/Move Tools> Objects> deselect the Object

2. MAIN TOP TOOLBAR> UV View label to see the Unwrap UVs

3. MAIN TOP TOOLBAR> 3D View

4. RIGHT COLUMN> TOP LABELS> Sculpt + RIGHT LABELS> Layers

5. BOTTOM WINDOW> Sculpt Tools> Sculpt, sculpt the geometry!

Add New Subdivision Level

1. BOTTOM WINDOW> Select/Move Tools> Objects> Select the Object, it turns to yellow because it is selected

2. MAIN TOP MENU> Add New Subdivision Level or SHIFT+D

3. MAIN TOP MENU> Add New Subdivision Level Options> setup Subdivede UVs, Preserve Hard Edges etc…

NB: anche se viene aggiunto un nuovo livello di suddivisione quello di partenza non viene distrutto, si può navigare tra i livelli da tastiera con PGSU – PGGIU

4. Keyboard PGUP (Step Level Up) – PGDOWN (Step Level Down)

3D View Setup

RMB over an empty area> POP UP MENU> check Wireframe + Smooth Shading + Lighting + Grig
uncheck Gradient Background

BG Reference – Edit Image Plane

Sometimes you will need a background image as reference.

The easy way is import a Plane with UV and Ref Image from 3DS Max, ready to use

OR

Create a Plane and project an image inside Mud Box, following the next steps:

1. MAIN TOP MENU> Create> Mesh> Plane

2. BOTTOM WINDOW> Select/Move Tools> Rotate -> RIGHT COLUMN> Rotate X=270

3. 3D View TOP RIGHT CUBE> Arrow Icon> Orthographic, after click FRONT FACE of the cube.
Now we have a Plane on the XY Plane in a orthographic FRONT View

4. BOTTOM LEFT> Paint Tools> Projection

5. BOTTOM RIGHT> LABEL Stencil> ‘Circle Arrow’ icon> Add Stencil> Select the imported image from the list>

6. See also RIGHT COLUMN, now there is the Stencil Image

7. S+RMB -> scale stencil
S+MMB -> move stencil
S+LMB -> rotate stencil
Q -> hide stencil

8. MAIN TOP MENU> Edit> Edit Stencil> FLOATING WINDOW> Display: Monochrome/Transparent/Opaque

9. BOTTOM LEFT> Sculpt Tools> Grab -> paint over the stencil to edit it
BOTTOM LEFT> Paint Tools > Paint Brush -> paint over the stencil to edit it

10. At the end> FLOATING WINDOW> ‘Save As’
After saving you will see the new stencil on BOTTOM RIGHT> Label ‘Stencil’

BG Reference – Paint the Stencil over the Object

1. Select the object -> RIGHT BOTTOM> Label ‘Select/Move’> Objects icon> LMB over the object

2. Create a Paint Layer -> RIGHT COLUMN> small icon on top left> ‘Create New Layer’> Paint Layer / Diffuse

3. Select the projection image -> BOTTOM LEFT> Paint Tools> select ‘Projection’> BOTTOM RIGHT> Stencil> DOUBLE CLICK over an image, you will see it in the RIGHT COLUMN and in the Viewport

4. Deselect the Object -> RIGHT BOTTOM> Label ‘Select/Move’> Objects icon> LMB over an empty area in the viewport

5. Paint over the object -> select the Paint layer> paint over the object

6. At the end hide the stencil pressing Q on the keyboard or uncheck ‘on’ of Stencil in the RIGHT COLUMN
