I know this is a cross post but it's just not getting anywhere on the beginers forum and I guess its more suited for here anyway.
Well I can get pretransformed vertices on the screen just fine but its the non-pretransformed ones that I can't get to show up, Nothing is failing, and all values seem to be what they should, and sprites render fine. This is very frusterating, and again everything works perfectly when im using pretransformed vertices.
vertices:
D3DXVECTOR3 vertices[4000];
D3DXVECTOR2 texture_coords[4000];
D3DCOLOR colors[4000];
vertices[0].x=-10;
vertices[0].y=10;
vertices[0].z=2;
colors[0]=D3DCOLOR_ARGB(122,0,255,0);
texture_coords[0].x=0;
texture_coords[0].y=0;
vertices[1].x=10;
vertices[1].y=10;
vertices[1].z=2;

texture_coords[1].x=1;
texture_coords[1].y=0;
