TGEA 1.7.0 Bug - Interior normal maps using incorrect sun vector

Unfortunately I did not get this one into TGEA 1.7.1:

The Interior rendering code was never setting the "light" for its RenderInst so it was using the default light which has the direction of (0, 0, 1) (straight up).

For normal mapped surfaces this means that it would display the normal map correctly on the bottom of the Interior but not on the top.

The best way to fix this is to go into source/interior/interiorRender.cpp in Interior::renderZoneNode() and change:

RenderInst *ri = gRenderInstManager.allocInst();
   *ri = *coreRi;

to:

RenderInst *ri = gRenderInstManager.allocInst();
   *ri = *coreRi;

   [b]LightManager* lm = gClientSceneGraph->getLightManager();
   if (lm)
      ri->light = lm->getSpecialLight(LightManager::slTranslatedSunlightType);[/b]

This will hand the the proper sun vector to any shaders that make use of it (and fallback to the default light if need be).

* I've seen a couple of other bugs that could be related to this but I'm not sure exactly where they are in the forums...
