Double Sided

Render both sides of the object.

Opposite

Flip the object surface sideness.

Tangent Mode

Choose a mode to compute the tangent space at render time. This tangent space is used to render the anisotropic reflections or the normal maps. Computing the tangent space consumes additionnal memory.

  • Disabled : The tangent space is not computed. A default but low quality tangent space is still available at rendertime.
  • st1, st2.. : Use the texture coordinate channel as direction for the tangent space.
  • Sphere : Project the tangent space on a sphere centered on the object.
  • Cylinder : Project the tangent space on a vertical cylinder surronding the object.
The tangent mode set to Disabled, st1 and Sphere

Enable Ptex

Activates the Ptex coordinates. You need to turn this ON to use Ptex textures. The Ptex coordinates consumes additionnal memory.

Invert t

If true, invert the t texture parameter (known as v in some softwares).

InvertT

Compression

Enable geometry compression This value globally enables/disables geometry compression. Note that enabling compression will usually reduce the geometry size by a factor up to 1.75, but will increase rendering time, and may introduce artefacts.
