About the Projection texture

The Projection texture converts a two-dimensional texture or image file into a three-dimensional texture by projecting it in one or several directions.

This is the same method used by the sMarble and sWood textures, so you can, for example, use scanned or painted image files with the Projection texture to create a variety of three-dimensional wood or marble textures. The Projection texture is also useful for converting a surface texture or image file to a solid texture to avoid texture distortion due to non-uniform surface parameterization.

Note the following when using the Projection texture:

• When using the Projection texture with textures that use fractal noise (for example, Fractal, sFractal, sCloud, sMarble), keep the Recursion Depth Level_min and Level_max values as low as possible to minimize rendering time. See Recursion Depth in Render > Multi-lister .
• You can use the Surface Placement and Label Mapping parameters of a texture that is mapped to a Projection texture to adjust the projection effect.
• You can create a Projection Object before creating the actual texture in the Multi-lister, by using the Render > Create Texture Projections tools.
