I was reading through the Houdini docs and got to the subdivision op. I think I recall reading that the crease parameter is not respected by Mantra due to patent issues with Pixar. Is this true? So no creasing in Mantra? What is the work around? Creating my own crease by doubling up another set of edges right near where I want the creased edge to be?

Hi there,

Crease is supported in Houdini with the Subdivide and Crease SOPs. However, the Crease attribute is not picked up if you set the Object's Geometry parameter (found under the Object's Render tab) to “Polygons as Subdivision Surfaces”.

Cheers!
