Hi Luchare ,
it would be interesting to know for sure if that's due to bugs. I've never really played around with the mat editor a lot, so I can't say anything useful in that respect.
It is indeed not that simple to copy or analyze the more complex stuff... It takes more than some basic knowledge about the interaction of the different settings and possibilities in the Material Editor to know what does what exactly. And in the DTE it gets really difficult...
Writing down stuff you find out is very useful in the long run, I do that all the time because it often happens that I don't know what the hell I did It's a lot of additional work sometimes, but it usually pays off sooner or later, so I would certainly encourage your idea to take some notes (or make screenshots even)...
And yes, it's true that many people here don't say very much. ShareCG currently is more a download database than a 3D meeting place full of life and communication, but maybe this will change with time. It would be great to get to know people here a little better and I'm sure we could learn a lot more from each other than just the number of hits someone gets for their uploads...
