Is it correct, that in order to use lightmaps (video::EMT_LIGHTMAP...) I _need_ a mesh with two sets of UV-coordinates ?
Or is it possible to tell Irrlicht to use the first set of UV-coordinates for the second texture too?

I have problems to load such a mesh with two UV-coordinate sets with Irrlicht. I created one with Ultimate Unwrap3D (UU3D) and saved it as *.x-file, but after loading

Code: Select all

smgr->getMesh (<my_mesh_file>.x");

... I tested the vertex type and got EVT_STANDARD, not the desired EVT_2TCOORDS.

Which one of Irrlicht's mesh loaders is able to load and preserve _two_ UV-sets ?

just read that Irrlicht supports Gile[s]. I use that with Blitz3D in the past (B3D-exporter).

How should I export from Gile[s] to import it in Irrlicht ???

... and me again

Just found out that I can use My3DTools to import from Gile[s].

But please answer my first questions, see above.

Thanks in front.

It did not work for me, thats why i use OGRE now. Its a pity thats its the only reason. I will probably return if someone gets it baked. This ducks sick.

I cannot see a good reason to have a lightmap and color layer on an object, with same uvmap set. Instead, you can paint shadows/lights directly on color map (texture). Lightmap is usefull when you use tiled textures... in this case, the uvmap sets are completely diferents...

ProSoft is right.
But you can do this in Irrlicht easily, just read the idea and function in http://irrlicht.sourceforge.net/phpBB2/ ... hp?p=45575
