The ILTTexInterface supports everything ILTTexMod did and more. Really, we're doing this for the same basic reason we are removing ITLCustomDraw. The only change here is that you won't get the ITLCustomDraw interface on the callback. You should query for the DrawPrim interface and use it instead. We're also considering changing the name as many people have misunderstood what it's for.
Processor now supports selection of an inverse quadratic falloff lighting model.
This lighting model matches the D3D and PS2 model lighting equations. This lighting model generally yields more realistic lighting. Note that if you have built your levels with the older lighting models, your levels will probably appear darker and you will probably need to increase the radius of many of your lights to compensate. The renderer now statically links to the engine. Both of these libraries contain early development of some of the new communications and multi-protocol management classes that will be fully integrated into the engine in the next major release.
