[Gvsig_english] alpha channel issue

[Jordi Torres]

Hi Jan,

You are right, it seems that 3ds importer on OSG (the scene-graph used in
gvSIG 3D ) cannot import textures with alpha correctly. We are investigating
which importers works well with this kind of textures.
Meanwhile you can use this workaround: use materials with alpha instead of
textures with alpha, because transparency in materials are well supported.

Cheers.
