See PxrDisplace for how to add scalar and vector displacement as well as displacement layers.
- Add a PxrDisplace VOP to your RIS Network. Wire your displacement map such as creating a PxrTexture VOP or PxrPtexture VOP for textture or ptex respectively. We can wire a shading network also.
- Add shop_displacepath to your object. Drag this parameter to the Material folder on the right.
- Drag the pxrdisplace VOP path to the Displacement Shader.
- Last but not least, you need to set your Displacement Bound to see the displacement.
Trace displacements is on by default.
