Hi, I must put a texture over a 3d map made of triangles. Those triangles are drawn using TRIANGLE_STRIP function. I tried to set the right coordinates of the square map, but nothing. this is the order of my map vertex: _______________ |8\ 10\ 12\ 14| |9 \11 \13 \15| |_____________| |0 \ 2 \ 4 \ 6| |1 \3 \5 \7| --------------- to texture this, I use : bottom left = 1 bottom right= 7 top left = 8 top right = 14 But It does not work. I hope I did explain myself enough. Thanks. Rex.
