First of all, the work you've done here is great, good to see 3D developing well on Silverlight!
I've had some trouble with models that I've exported to .ASE from 3DS MAX. The models look fine in 3DS MAX, but when I import them into Baldur, they appear to have triangles popping out everywhere.
I've included an example here:
Is there a different product that I should be using for modeling that you find better? Or something that I can do to prevent this from happening when exporting?
