Vertex limit 65k?

[shadmar]

Hi

 

I recently learned that surfaces can hold 65k vertices ~ (130k faces), but when I try creating a simple plane in UU3D of 65k vertices it gets distorted like this :

 

 

I can successfully render upto 65k faces ~ 32k vertices.. but not 65k vertices. Is there somthing wrong with the mesh I'm creating? (attached).

For me 32k vertices is the limit also, above that I get those long triangle mess too.

I'm betting your exporter creates additional vertices to accommodate different texcoords, normals, etc.

Hmm, I ran this through GMFDump and the vertex count for four surfaces is 65536, which should be the maximum number:

Yes, but it doesn't render correctly.

Yes something about this value you ran into is the limit per object. I have problems with it too sometimes. Especially for arch-viz things. You need to split in more objects (some engines do it in the export).

[Josh]

His file should work as it is.

why don't you support 32bit indexes ?
