Hi,
I think you are having an issue with the size of your Reflection map. Try increasing the resolution of your map. This should fix it. If not let us know.
The Hilight Sharpness & Brightness parameters are also inportant as well as the size of the elements that are suposed to produce the reflection (Masks, layers, Effects…)
If you want you could send me an aep with your object an reflection map to trouble shoot.
BTW, did you check the CD cover project I posted a while ago? This may also help.
Salut.
Serge
