Hi, I need to update the q texture coordinate, but when using quad strips, I have discovered that this may not be possible. Quad vertices are provided in this order for my quad strips: 0------ 2-------4 | /| /| | / | / | | / | / | 1-------3-------5 The only shared attribute between two adjacent quads are the vertices (2 and 3 above), leaving the q coordinate dependent on the quad. When vertices 4 and 5 are provided, they complete the second quad, but I don''t know how to update the q texture coord for vertices 2 and 3. Any ideas or am I missing something?

This appears to be a tougher question than I thought.
