how to set up multitexturing?

billybob · 2002-07-27T13:32:43

i have this vertex: struct terrain_vertex{ FLOAT x, y, z; // The untransformed position for the vertex. FLOAT nx,ny,nz; FLOAT tu, tv; // The texture coordinates FLOAT weight; //the info for multitexturing the terrain, allows for 3 textures DWORD matrixIndices; FLOAT weight2; DWORD matrixIndices2; FLOAT weight3; DWORD matrixIndices3; }; and this fvf for it: #define TERRAINVERTEX (D3DFVF_XYZ|D3DFVF_NORMAL|D3DFVF_TEX1|D3DFVF_XYZB3) now how do i use this setup? i got this far reading the dx documentation, but i can''t figure out how to use it. i realise it may be a larger than postable topic/tutorial, but does anyone know of a tutorial that teachs this?

Ah I misunderstood. The textures are set for the stages and one of the default arguments for stages 1 and 2 are the TEXTURE. Ok, sorry, thought he meant about the FVF structure.
Looks cool though! I got my geforce today, I''ll have to finally implement that myself.

it looks GREAT, but i''m having trouble making my vertices stop connecting from one edge of the terrain to the other. it keeps making triangles with opposite ends of the terrain, making huge strips of lowres garbage through the pretty terrain
