Sorry, I've made a mistake about the 2 UV set support... I double checked and yes, unfortunately it support only 1 set of UV for the OBJ format.

You should try collada then. This format is slow, but is made for interexchange. But I've never tried it much with Irrlicht. Once you have the model in Irrlicht for speed you could save it in .B3D from there.

Mmm.. I did once try to load two identical objects with differing UV sets then
tried to programatically transplant one set into another.
The problem was that when I exported these two objects (one with plain UV Map and one with a Lightmap)
the indexing into the data in the model changed causing bogus memory index reads.

All I know is that if I could get two identical versions of an object where only
the UV Locations differ, then a First item could be load and set (in irrlicht) to have 2 UV sets .
Then the second object is loaded and its UV locations transplanted into the second UV Map i.e. Lightmap..
(the second object would then be dropped of course)

The issue, I think, is to get a "3D App Title" that can export two objects with IDENTICAL UV Index Refs yet different
UV positions.. (still looking)

IRRB seems to be the only way this can be done easily (and only from blender) and in very large ascii format..
(a working binary form of IRRMESH could help)

The last resort would be to write a complex routine that would analyze the two model polys and "smartly" match up
the UV Locations..

I'm wondering now about Copper Cube and IRR Edit..

An interesting problem..

Reached a point where smart shaders and deferred rendering etc won't mean much without a good "Scene Management System"..
Trying to learn Irrlicht's "Scenegraph"..
(still not able to properly inter-relate my own classes publicly to Irrlicht classes like "ISceneNode")
