i render alot of triangles and now i load them with a texture instead of just color and alpha.
it works with both alpha and textures.

but my problem is that there are multiple textures on each triangle. Is there a way i can scale this?
so the texture is bigger and covers more of the triangle?

this is how i render my triangles:

[source lang="java"]d3ddev->SetTexture( 0, g_pTexture );
d3ddev->SetStreamSource(0, v_buffer, 0, sizeof(CUSTOMVERTEX));
if (texture)
d3ddev->SetFVF(VERTEX_FORMAT_TEXTURE);
else
d3ddev->SetFVF(VERTEX_FORMAT_NO_TEXTURE);
d3ddev->DrawPrimitive(D3DPT_TRIANGLELIST, 0, (lstTrangles.size()*3));
[/source]

Generally you manage this through your texcoords. So if you want a texture to stretch over many triangles, you set the texcoords so that the will only use the area that is necessary for them. You texcoords specify how much of the texture you want the triangle to receive.
