..after reading some stuff, I realized that renderer rendering actually behind scene, twice same geometry with applied lightmap (in case that geometry can carry 2 UV map sets as B3D file format)...so, maybe i get all together wrong, but is that mean that Blitz3D actually doing that behind scene?? Rendering twice same geometry, once for difuse textures /UV map1/ and second pass for Lightmap /UV map2/ ?? How Blitz dealing with it?? Using Vertex buffer or what?? I would like to hear really some serious answers on to this question regarding Blitz3D, from SimonH or Mark or whoever for sure knows whats going on behind scene...thanks in advance..
