There seems to be a lot of confusion (including mine) about where to post materials/textures. I see .mat files mixed in with 2d, mixed in with landscape eco's, etc on both upload areas. I think this needs to be better defined as to what goes where.
For example; 3d .mat files including mixed materials (landscape and eco type materials including bumps) in one section and 2d type texture materials in another section- clearly defined by the webhost.
I posted my mats to the Texture area after clicking on it first and seeing the many .mat type materials there. But then going to the Materials upload section I see much of the same.
It's all mixed up and needs more clear definition of upload types.
