Okay, so I've been checking out the MLG Halo 3 Forge Forums and saw that there was a database of sketchups. There are some that people posted, saying that they are up for adoption and didn't mind if someone made them. I was wondering if you are allowed to just take the idea and start forging it without posting on those forums that you plan on making the map (because I'm currently not a member of the site).
Obviously it would be polite, when you finish the map, to tell the person you used their design and to also credit them if you post it on any forums. But when people put their stuff up for 'adoption', they generally do want someone to continue with the project if they want to, its understandable with sketchup because a lot of the time its much much easier to design brilliant maps on your PC than it is to actually build it in Halo 3.
Allright cool, thanks for the answer. I was planning on giving them credit if I used any part of it, I was just checking.
