I didn't reply because I don't understand what you did/are trying to do. For example, when you say you changed the LoadAnimMesh code I assume you also exported versions of the model to the appropriate file formats. Given that, some simple reasons you might not be able to see a loaded model include camera placement (ie. the camera is too far from or inside the model) and surface color (eg. a black model on a black background won't be visible.) Sorry if these seem like obvious things to check but since you didn't explain much in your question I don't want to assume anything.
There is no specific reason models exported to 3ds or .x shouldn't show up (although, because bones aren't supported, there won't be any animation.) Drago's comment is not applicable since 3ds doesn't even support bones in the file format; a skeletal animated model exported to 3ds will be exported as a static mesh. It won't be moving but it WILL show up on screen.
