lunlam Posted February 1, 2007 Share Posted February 1, 2007 Hi all, I am trying to write a geo exporter for maya. I also want to transfer crease defined in mtor. In mtor, multiple maya sets containing edges are used to define the crease weight. PRMAN's subd tag also defines crease on edge set basis. e.g. ["crease" "crease"] [2 1 2 1] [1 2 5 6] [20 20] That means prman will render 2 edge sets of crease value 20. But I find that houdini only have one creaseweight attribute. My question is how to map the value from mtor crease sets to houdini's creaseweight attr?

edward Posted February 1, 2007 Share Posted February 1, 2007 Since the creaseweight attribute is a vertex attribute, in theory, it's possible to have different crease values on either side of an edge. I have no idea what it means though to have different crease values on the different sides of an edge though. Quote Link to comment Share on other sites More sharing options...
lunlam Posted February 1, 2007 Author Share Posted February 1, 2007 I figured out how to do that. The creaseweight of a edge in houdini is defined by two vertex. What I need to do is to find out the corresponding edge in MTOR crease sets. and assign the value to the vertices. By the way, does houdini support corner tag of prman?
