Extra UVW Channel in PVRGeoPOD


I’m using the Maya POD exporter and I want to export a POD with an extra blank UVW channel so that I have an interleaved data structure that works well with glDrawElements, VBO’s, etc. The second UVW channel will be populated at runtime with camera-dependent UV’s. The trouble is that even with ticks in all the UVW1 tickboxes, the POD only shows up with 1 UVW channel. IS there something you have to do in Maya to get the extra channel to export?
