As i was working on my textures, looked again at the general organisation of the game textures. I would recommend to move all textures of one group into one folder, the actual system is very weird with the numbers. I have to search hours to find the right texture to replace. Some subfolders for woodenblocks,woodenplanks,plaster, etc... would be helpfull.
Another point i want to pick is the number of textures itself. For many it is great to have such a large number of building materials, but i think that it is too much. For instance we have 4 sandstone textures and we have 8 or so plaster. I even want to say that i miss the consistency of it, we have no "types" of wood or stone. My idea is to remove some textures from the game and wait til they are needed by content. E.g. new Tree, new natural Stone.
