Irrlicht Engine

hi,

is there a way to avoid the artifacts on intersecting polygons (tris)?

is there an editor i can se to import obj/vrml files and then texture polygon
by polygon with serveral textures (256x256 etc.)? (Not Unrealed, GTKRadient or Woldcraft/Hammer)
I am asking that because i need a file format that allows using separate polygon selection to texture with diffrent tiles.

I can not export any format with correct uv's out of c4d .... just vrml2 is working well but that does not support texture selections.

cheers,
chris
