Collada2POD doesn't export colors?

Because I failed to get the 3dsmax9 exporter to properly export vertex colors, I thought I’d try going from max -> collada -> Collada2POD. However I can’t get any vertex colors to export at all w/ the Collada2POD exporter.





Is there a trick to this? My DAE file is crazy-simple.

Hi,

 

Collada2POD should export the vertex colours. Are you using the most recent version? If you are could you send your collada file and your .pod file (so I can use the same export options) to devtech@imgtec.com.

 

Thanks,

 

Scott

Thanks. From your email I see you are using Collada2POD from the 2.02.0756 version of our SDK. Support for vertex colours wasn't added until our 2.4 release. I've tested your collada file with the most recent version of Collada2POD and the vertex colours are being exported correctly.
