that makes sense, yeah. thanks -i'll bear that in mind things can get messy pretty quickly! I getting the hang slowly... i need to present the folder to a tutor for marking -- but they're requesting a 'lite" version with just a few incremental saves etc. -- will it work if i move a section of finished versions into one 'scenes' folder, all the textures into one folder etc. - i can imagine the textures getting lost..?
