*This is an excellent tip, I never actually noticed that some transmapped items don't get shiny when highlights are applied. The funny thing is that I still don't know WHY this trick works. ;)*

A lot of rendering engines (ever true ray-tracers like POV-Ray) have trouble applying highlights to anything that's 100% black. The sphere on the left has an RGB 0,0,0 texture map applied, the one on the left is RGB 32,32,32 - both have the same highlight settings. As dodger pointed out though, it's essential to have 'Apply texture to highlight' checked for this to occur.

Odd exception - while Poser won't hightlight a 100% black texture map, it will highlight an object with a 100% black material setting.
