The only video tut on 3D paint I know of is the short part on the CD "Decaling / UV Setup" from Zandoria Studios. If there is another one, please let me know! While this tut is very valuable it is pretty much limited to using 3D Paint for merging decals. Also, the 3DP manual does a good job of telling you 'how' to use the program but not a lot on 'what' it can be used for.
I'm considering creating a video tut on what 3D Paint can be used for, techniques as well as a quick start. I think this is something that would be valuable and something that is 'missing' that needs to exist. Unfortunately, for the 'what it can be used for' and the 'techniques' part, frankly, I simply don't know at this point. I'll have to play around with the program and 'discover' these and this could take time.
However, some out there have used 3D Paint for some very impressive work. I need your help... I need you to post any techniques and usage you have discovered so I can add it to the tut. The tut will naturally be a 'forum' effort and you'll get glowing credit and accolades!
If a group effort can be made, I'd post the script for the tut here for all to critique before creating it. Also there would be this thread which would contain a lot of the content. I'd probably only charge $500 for the tut and of course keep all the money for myself (JUST KIDDING!!!!). It would of course be free.
This effort will probably fall on its face (I'm not real good at starting up 'group' efforts LOL) but hey, its worth a try!
