Why does some of my geometry appear as lack inside the rtre viewport?
If after lighting your scene and viewing in rtre you notice some of the geometry has turned black it is likely that Extrude, Face Extrude or Bevel has been used on a sub-object level, this is fixed by placing a smooth modifier in the modifier stack underneath rtre lighting then tick Automatic, once you have done this go to the rtre lighting panel and click update. Another possibility is that the Diffuse and Ambient values of the material being used is too dark, make these values a neutral grey, or lighter, and re-light with rtre Lighting. If you have imported a Lightscape mesh and it appears black in the rtre 3D View, confirm that the modifiers: LS Colors and LS Mesh have been applied to the model.
