Renderosity has strict guidelines you have to follow....I for one agree with you and I prefer to put the textures in the same folder as the MATS to avoid an extra folder in the Runtime/textures directory and also so if you want to find them you'll always know they are in the same place as the files...but Renderosity terms won't let me do this...it specifies that I have to make a folder with my name on it ( or something to that effect, I can't quote it right now) for the textures.....so don't put all the blame on the vendor...as a result I rarely unzip to the specified folders and just place the files where I want them...usually the textures with the pp2's or cr2's....
