VERTTYPE pfColourBackground; /*!< Background colour */
VERTTYPE pfColourAmbient; /*!< Ambient colour */
We write the PVRGEOPod exporter here, so we do have the source code for it. However, it’s not policy to release source code for the POWERVR utilities or plugins.
Our exporter doesn’t set the background value, I believe (but it can be set in PVRShaman, for instance). The Ambient value comes from the Max Interface::GetAmbient function.
In what way do you want to extend the POD format? We may be able to offer advise on how to do it…
