Thank you Arno! I've found that if i delete one truck from that scene, and reexport, then it works, its opening and compiling woth MCX. So maybe the problem is in model? But i can't imagine what that can be...
So. With latest version i can open it, but then i see all objects like this
They all are now floating in the air.
And again it's all because of one model from the scene. Whitout it all seems to work fine.
So what can cause this problem? This particular model was made like all the others. In sketchup, imported in max for texturizing and export.
