hm, well you're right about it not being picky coz my project folder is a mess but everythings still working...
i think it's more that i'm having trouble knowing exactly where I need to set the project folder. say i've created a street scene with vehicles (which i haven't, but lets pretend..) i've made a subfolder for 'street' and one for 'cars'. when working on the cars i've pointed the project 'set' folder at the 'cars' folder, and i think i'm right in assuming it's created all the subfolders in there again, including another 'scenes' folder.
then, sometimes I've saved to 'cars' and sometimes cars>scenes wich has led to some confusion.
I'm a bit concerned when I get round to applying textures etc. i'm not going to know whats where...i guess it's just a case of developing a workflow
