Ok, I'm going to take a shot at uploading an item to the free stuff. Its a an .obj model I made and the model is ok to share. I want to include .mat file textures. The .mat's are a reworked version of a Bryce preset (as are most I suspect since very few folks have DarkTree or any other procedural texture program). Its for commercial or non commercial use. Any thougths about this? Can you see any complications with copyright or any other issues I should consider?

The Model is yours. The texture has been changed. As long as you state the facts in a "README" in the ZIP, the resposibility falls on the user. They could use any texture or variation, bryce or not. Disclaimers ARE legal. Now I'm intrigued, your stuff is nice.

Thanks for the compliment, but all I have are a few trinkets. But its a start. Ok, I kinda agree with you and will wait to see what others say, including some scans of the copyright forum. Just wanted to dot my I's and cross my T's. I'm trying to put up a glass cup that is not the subject of this post and eitehr osity went down on the aborted upload or I did something horrendous to get locked out for a few hours.

Ok, I put my coffee cup up in the free area without a texture. I looks great with the standard diamond texture in this image, but when I attached that for export it came back into bryce as almost transparent. I have a lot to learn. Will upload the donut with the bryce textures later, let me see how the bandwidth goes on this one first.

The .mat files are copyright Corel, so I don't see a problem. In fact I don't see how someone can upload a bunch of Bryce skies and say non-commercial use only because they can't claim copyright on them, so how can they restrict usage? Presets are presets. For example, Curious Labs claims copyright on their presets (lights, cameras, etc.) and state noone else can claim copyright though presets certainly can be distributed. The only problem I'd see with .mat files would be if they contained a 2D image, then someone could claim copyright on the image. But not purely procedurals. However I've seen .mat files with images that are otherwise freely distributable being restricted to non-commercial use only and I don't think this is enforcable.
