It appears that there is a max number of tris per mesh of 32768. It there a way round this or to increase this?
I'm trying to merge more meshes to reduce the number of entities as its killing the FPS.
I don't think merging meshes (to over 32768 polys) will help. Perhaps you should reduce the polys.
With add mesh instead of getting 7 FPS with 16000 cubes I get 85 FPS, so it does work!
No, there's no way to get around it. I believe you're also limited to 65536 vertices per surface. Or maybe it's actually the vertices that are the problem for you. Either way, it's a directX limitation.
No real problem though, surely? Just merge to 2 meshes instead of one.
Have tried that and its fine now have another problem. It appears I cannot setup collisions with my new merged mesh and a sphere. Get memory address error.
