mib_bump_basis

 
 
 

Category: mental ray > Texture

Shader Family: Texture

Output: Vector

This shader is a bump basis generator. Given the intersection point, it computes a pair of bump basis vectors, based on the projection method.

Name

The name of the shader node displayed in the render tree. Enter any name you like, or leave the default.

project

Specifies the projection to perform: UV, XY, XZ, YZ, spherical, or cylindrical, as described in Texture Space Mapping for the mib_texture_vector shader. All projections are based on the 3D point in space after conversion to object space. This parameter is used to orient the bump basis.

ntex

The texture space to use, in the range of 0 to 63. It is used only if project is set to UV (5) or disabled (0 or negative); otherwise, ntex is ignored.
