Problem with loading 3ds file

Hey, I have this problem and I'd want to see if you could help me with it.

I'm trying to load a 3ds file I made in 3ds Max, but when I load it maybe half of the geometry is missing...

It's an export problem or loading problem? I'm gonna try with another format anyway but maybe I'm missing something!

Can you provide a link to your mesh? Also try splitting it into more materials, you probably have more than 65536 vertices in one mesh buffer

Yes, sure.

There are some problems with the loaders not supporting 32-bit indices yet, but you should know that your scene isn't optimized for realtime 3D. You can't just throw a 3DS Max scene into a 3D engine like that, there's a bit of an art to modeling for realtime graphics. Rather than using geometry you should use texture maps to add details to your world

Hmm.. I see, then I'll try to lower the polygonal charge of the model so it isn't that much fat!

Thank you!

i'm also facing the same problem with my 3ds models. i made them in Max 2009. But when i import the same as .obj the model loads perfectly. Is it the 3ds importer problem?

3ds should have an automatic split mechanism, which should never exceed the 16bit index limit. However, 3ds format is not very well supported in many aspects. So it might be better to use a different format...

Yes, but 3DS has a very less storage requirement than other formats.

You mean in terms of file size? Well, just zip your .obj files and it's equal. Moreover, the 3ds files do generate new vertices for each polygon, which means that the require far more GPU memory and bandwidth, and the latter is usually far more expensive.
