Re: Black Spots On Renders
-----------------------------------
:hi: 
As you describe it now it is quite likely old P4 engine doesn't work too well with your graphics device.
Only one thing left I can think of is fiddling with the OpenGL setting of your graphics driver.
In your place I would consider keeping P3/4 just for evaluation purposes and do the serious work in P6.

PS: Generally,  try applying the shadow map setting for your P6 /P4-renderengine anyway.
At least for the main, shadow casting light source. For the back lights you should reduce the overall shadow and light strength. I tend to turn their shadows off completely.
That's just a hint from my experience working with mapped shadows, and a matter of taste, too.
