Although you can use the 3D
Paint Tool to modify a texture by painting directly on
the surfaces the texture is applied to, you can also modify the
texture in the canvas and immediately see the effects on the surfaces.
To
modify a texture applied to a surface
- Apply the file texture to the surface.
For details, see the Shading guide.
- Open Hypershade,
if it is not already open (
Window > Rendering Editors > Hypershade).
- Using the middle mouse button, drag the
applied file texture onto the canvas.
TipTo paint on Maya
textures (for example, checker or fractal), select the surface the
texture is on and in
Hypershade,
-select
the texture. Still in
Hypershade,
select
Edit > Convert to File Texture (Maya
Software). Now drag the converted file texture onto the
canvas.
- Select Canvas > Save >
and
turn off Save Alpha.
- Set Paint Effects to
save the canvas after each stroke (Canvas > Auto Save or
click the folder icon on the toolbar).
- Change your layout to display both the
canvas and a view of your scene (for example, Panels
> Layouts > Two Panes Side By Side).
- In the scene view, turn on Hardware
Texturing (Shading > Hardware
Texturing).
TipTo improve the display
quality of the texture, open the Attribute Editor for
the shader, expand Hardware Texturing, and change
the Texture resolution to the desired
setting. On Windows, you may need to set the quality to something
other than Default to see the texture update.
- Paint on the canvas (see
Paint on the canvas).
The texture updates on the surfaces it is applied to each time you
release the mouse button.
TipYou can paint attributes that you can’t see through
Hardware
Texturing (for example, bump, incandescence, transparency)
and see the effect on the surface it’s applied to using IPR.
- Assign a texture to the required attribute
of the shader and apply the shader to the surface. For details,
see the Shading guide.
- In Hypershade,
use the middle mouse button to drag the texture node onto the canvas.
- Set Paint Effects to
save the canvas after every stroke.
- Do an IPR render of the surface and select
the area you want to view. For details, see the Rendering guide.
- Paint on the canvas.
