Thank you - your program worked very well on my model.

I found information in the Bryce forum and apparently there is no way to select just part of a mesh to apply a material. Your program broke my object into 4 objects and I was then able to select each and apply different materials in Bryce.

The key word in your program description is "sharp edges". I ran the program on a model with curved surfaces and radiused corners and it did not break apart.

Is there any possibility in the future for the user to select an area directly, or perhaps define the threshold, for object division?

Regards,

Ed
