[quote]Hi,
I like to display a tree model which I exported from XFrog. I tried the 3DS and AC3D loader from Kevin. Both were capable of loading and displaying the model, but both had problems with the transparency of PNG and GIF textures.

GIF? Why not always use PNG? Because PNG should work. Transparent PNGs work fine for me when I use Kev’s newest 3ds loader from his website. He implemented this feature 1-2 weeks ago. 
Is your PNG packed correclty (as 32 bpp PNG, consisting of the 24 bpp texture plus 8 bpp Alpha layer in one file) ?
Well, what’s conerning the 3ds output quality of programs like DeepExploration, I’ve to confess it’s not really good with all models.
I’ve found many models which when being exported from DeepExp to 3ds and then loaded back again to DeepExp, they’re corrupted. 
For example I’ve usually to disable DeepExp’s export option “save hierarchy” otherwise I don’t see anything in the 3dsloader.
Ant has found a more working way, but it’s way too much for me (export from Maya as .mb and then convert it via Polytrans-for-Maya as 3ds, oh oh oh).
It’s amazing to see how badly many 3d exporters write a format like .3ds or .obj, it looks like everybody defines their own “standard”. 
PS: Ant, isn’t there a nice .3ds exporter plugin for Maya (without using an expensive Polytrans) ? I know a Maya fan but he doen’t have Polytrans (and doesn’t intend to use it).
