Hi guys, I wouldn't normally like to interrupt the threads main topic of DirectX but I thought it's best spoken here as its DX I'm having the problem with (I think). I've been trying to render curved surfaces from the Quake3 BSP file format but my polygons come out all crazy such as triangles spanning ridiculous distances across the screen and vertices in stupid places all over the world. I've been using about 5 references (the common Quake3 BSP demos out there on the web) and tried the EXACT code of all samples and still no joy. However, the only difference I've added myself is the renderering of the vertex/index buffer and I feel it might be the way I'm issuing the draw calls to DX. I beg of someone to please show me working code of Quake3 BSP Curved Surfaces in DirectX! Have sympathy, I've been on it for days now :( Thanks, MeshMan

EXCELLENT!

Enabled Direct3D debugging DLL's and maximum validation and it told me i was giving it a wrong FVF to the size of the actual vertex. So I changed it, and BANG, works!!

Can't tell how joyed I am to see my Quake3 map finally rendering after days of fiddling on the same problem!

Thanks Jack, nice video work in the other thread btw!
