terrain engine texturing prob

Just create an additional quad and draw that. You can use a z that''s 0.01 higher or a z-bias to ensure it''s seen.
Check out tutorials for decals, because basically that''s what this is.

Can you afford giving each vertex another texture coordinate?

Raloth: No I suppose I cant.
Fidelio66: Yeah I guess I''ll have to do that.
Thanks guys

Actually what exactly are you getting at. Do I need a new VERTEX or just a new pair of texture coords in my custom vertex? How would I do that then?

Keep your texture info in the triangles, or tiles, instead of in the vertices. I keep a list of vertices and a list of triangles for my meshes. The triangles are set up like this:

struct
{
     int   vertex_index[3];
     float u[3];
     float v[3];
     int   material_id;
};
 

The vertex_index holds the index to the triangle''s certices in the vertex array. The vertices themselves hold no texture info.

Well, actually, I store material_id per mesh, not per tri, but you get the idea. My models can have more than one mesh.

yckx: Wow, thats good. But how does one implement it technically, with coordinates in VERTEX its SetTexture and set the appropriate VERTEX_FLAG. What DirectX calls do you use?
-CProgrammer

Um, I don''t I use OpenGL. I haven''t tried to learn DirectX yet, so I can''t really help you with DX implimentation. Hopefully, someone else will speak up and guide you. Also, I should mention that the idea of storing tex info in the tri instead of the vert isn''t mine. I changed my code after I saw the ms3d file format specs.
