Houdini 20.0 Nodes Geometry nodes

Verify BSDF geometry node

Verify that a bsdf conforms to the required interface.

Since 14.0

This node provides some useful checks and balances that can be used to verify whether a cvex_bsdf conforms to the required interface. It works by randomly sampling and evaluating the bsdf with point samples, and will additionally show a visualization of the shape of the bsdf as a point cloud.

By default, the Hair BSDF’s R component is used. Modify the verify_bsdf VOP SOP inside this node to change the BSDF.

For more information on how to verify a BSDF with this node, refer to the sticky notes inside this node.
