Yes, saxon. The patch is more like I expected the program to work. But there still some very seious problems. The face room lasts about 15 seconds before "Caught C exception..", even after the patch. Exactly the same render setrtings as the release version of the renderer Little_Dragon. So, yes it is all patch. Especially notice the procedural textures in the reflections. (The glowing Pipes) wgreelee1, The intent here was for an ambient look to the light. The celing glows orange, light comes from all the plasma conduits behind, and the control panels. Even the glowing fog below is represented with an infinite light. None of these cast shadows, because (Atleast in the release version of the render) the Cast Shadows check box on props doesn't seem to work for raytraced shadows. Taking the check off leaves these items casting shadows. Makes it a little rough to light a room using raytraced shadows. I'll have to test this with the patch later.
