   prt engine limit and handedness
  Hello, I'm trying to use the PRTEngine in my application. Question #1:My 3D engine follows the right-hand rule while DirectX follows the left-hand rule but what about its PRT engine?The Simulator takes as input an ID3DXMesh with an optional transform. I wrote a little converter from my scenegraph mesh to the ID3DXMesh, but I don't convert neither vertex position's nor transform's handedness: is this a problem?If I would convert the mesh from right to left, then how could I use the results in my right-hand rendering? In other words, does this prt depend on handedness?Question #2:I read in some post that there's a limit of 65k vertices or faces for blocker meshes: is it true? What does it mean?When I create a ID3DXMesh, how many vertices and faces can I put inside?Question #3:Could it be reasonable to apply PRT to a 1.5 million vertices scene?I'll be glad to give you more details if my questions are not clear.Thanks in advance,E.
