[Gvsig_english] 3D extension alpha channel problem

[Jordi Torres]

Hi Jan,

We need some information to track down this issue. Could you please post
your graphic hardware specifications, drivers and your S.O.?

Which format present this problem? Collada, 3ds?  If your data is not
propietary, could you post a example model?

Cheers.
