Hey people
Ive been doing some research into vector displacement with houdini, and was messing with the shader you guys have been working on. Looks like it has some problems with negative displacements. Theres a more detailed explanation here as well as a screenshot of the problem.
Anyone know why this would be happening? It be great to solve this as I have a vector displacement baker in works using Houdini and they would go great with each other. I cant quite see where the problems lies, the shader looks correct to me.
