A Clip map texture is a texture that clips the geometry. It behaves exactly as if a binary (on/off) transparency map was attached to its material except a Clip map renders way faster than transparency. Visibility of the surface is defined when the assigned texture average value is greater or equal to 0.5. For example, when a texture is returning a red color such as (1.0, 0.0, 0.0) it is considered as transparent. Indeed, (1.0 + 0.0 + 0.0) / 3 is less than 0.5. However, if the texture is returning (1.0, 1.0, 0.0), it is considered as opaque. Indeed, (1.0 + 1.0 + 0.0) / 3 is greater than 0.5.

Clip maps are assigned to shading groups. To assign a clip map, click (5) and select or create a new texture. You can also drag and drop a texture to a shading group in the Material Linker. In the same way, you assign a clip map texture to a single shading group. Assignments can also be done on a multi selection of shading groups.

 

Note

When using clip maps you don't have to check Enable Transparent Shadows on lights to see proper shadows.
