[away3d] how can I apply the texture on both sides of 3ds?

[juliancruz87]

I'm trying to add a texture to a model 3ds, but the problem esque
texture I get only one side, which method should I use from 3DStudio,
and as I apply it to away3D, this is an example of the inside. I would
like to see, but appears black.
thanks for everything
