I am having some issues exporting vertex colours from a collada file using PVRGeoPOD. No matter which of the 3 colour export options I pick, the colours do not appear to be correct in PVRShaman. Currently I am working around this by exporting the colors as ARGB and swizzling them in the vertex shader as vertex\_color.bgra. This seems a bit messy though, is this a bug or am I misunderstanding something here?

It may be a bug in PVRShaman where it’s not correctly interpreting the Data Type you’ve chosen in PVRGeoPOD (e.g. ARGB, RBGA etc.). You should be to verify this by right-clicking a mesh in the PVRShaman _Scene Explorer_ & using the _Open Data Viewer_ option.  
  
  
  
If you send a POD that reproduces the issue to [devtech@imgtec.com](mailto:devtech@imgtec.com), we can look into this for you.
