I've tried some of 3DTotal's Texture packs and I'm dissapointed. They're realistic but they lack flexibility. I mean what I'd like is textures structured in Photoshop (psd) files: each important element of the texture being a separate layer- this way, the possible variations and usability of the texture would be enormous, instead of having to messily erase small parts of a bitmap to suit my purpose. So, is there such a texture collection- that allows real flexibility (but not texture generators like Genetica)?

Hi, totally agree about 3DTotals. Texturama will add some to your collection. Seamless textures.

Interested to hear about any others people can suggest...
