hm...do you know how to compress somehow model to be under 1mb size? my models are over 2mb size
and game loads very very slow, total ping for bodies 18 000 ms, so I have to wait 5 minutes to load.
Problem is, when I editing and exploding meshes, over 1000 submeshes are creating, every of them with own uv and phong tag, and texture. Is there a way to compress all in one object, not just group them in one object(and with variant to explode them back in thousand pieces), but to make them the same object? Thank you a lot for support.

PS: i know, some of you can send me on google forums, where I found nothing interesting, and I hope that you know an solution
