I does, I exported a mesh from 3ds Max with the FBX exporter and it works, anyway there's nothing not to be supported since smoothing groups just create hard edges. The only problem might be with the original exporter, but I don't have acces to it.
Oh, it must be the CryEngine exporter then? I've checked the settings and I can't see anything related to smoothing groups. I'll use the FBX exporter then! Never used that for CryEngine, I assume I don't have to do anything too special?
cryengine doesnt really have any smoothing groups at all. Everything is rendered under a single smoothing group. When you export the mesh, the exporter splits all the hard edges in to 2 edges, so the mesh is physically in two pieces (albeit perfectly aligned).
Huh... well I've tried the mesh with 3PointShader, Xoliul and Marmoset, all works fine. I'm using the official exporter and I've done a test with a simple mesh and I have the same problem. Thinking about it I don't think I've had to use this kind of blending before in CryEngine... I guess it doesn't support it? That seems…
