The Diffuse menu is divided into two tabbed sections: Controls and Texture.
(a) Repeat Mode box (b) Mapping box (c) Camera Type box (d) Fit Method box (e) Filter box
Wrap (Geom UVs) Wrap mapping completely envelops the 3D model with the diffuse map according to the object’s diffuse coordinates. To use
this option, you must import a model that has its own diffuse coordinates. When using Wrap mode, you can also apply UV mapping
settings from the Geometry menu. See Using UV Mapping. ![]() |
Plane Planar mapping applies the diffuse map without distorting the front plane of the 3D model, similar to a movie projector casting
an image onto a screen. All 3D coordinates of the geometry are mapped to this plane to generate the diffuse values. Planar
mapping positions the lower-left corner of the diffuse map on the 3D model’s axis. When you apply planar mapping, any surfaces
on the 3D model perpendicular to the front plane cause the pixels at the edge of the texture to project along the “sides”
of the object. ![]() |
Perspective Perspective mapping is similar to planar mapping, except that it performs a perspective transformation of the diffuse map based on the selected camera’s field of view (FOV). When you select Perspective as the mapping type, the Perspective Camera box becomes active, allowing you to specify the active camera. The FOV of the camera has an impact on the resulting effect of any transform applied to the parent axis of the texture. On stereo cameras, the interaxial distance between left and right cameras also has an effect on the resulting perspective transform. |
Projection The texture behaves as if it is projected by the selected camera. Projection mapping is useful as an alternative to projecting textures using the Projector node, especially when it is necessary to project while preserving a specific camera POV. |
Select: | To apply: |
---|---|
Nearest | No filtering — the pixel of the texture closest to the screen pixel is displayed. |
Linear | Basic bilinear filtering. |
Anisotropic | Non-proportional filtering between X and Y (faster to process than EWA, but with a lesser quality). |
Aniso+Linear | A combination of Anisotropic and Linear filtering. |
EWA | A high-quality elliptical weighted average filter to produce enhanced rendering results (slower to process than other filters). |
EWA+Linear | A combination of EWA and Linear filtering (offers the most advanced filter processing). |
