3ds max object to opengl <p>I am trying to assemble a scene in opengl, using already made objects. The problem is that the object are in .max format and have no external textures.

I think Autodesk also has their own toolkit for doing this.</p>

Currently the standard deserialization works fine, including the enums, but <em>now</em> I want to convert an attribute into a class. Oh! ... | <p>This is not supported in a declarative way. You will have to implement IXmlSerializable on the parent class (the one that is serialized to an element) and perform the conversion between the string and the MyValue type manually.</p>
