Trying to use the tool for some simple 3d pixel-y objects, one thing I found is that I have to enlarge my 64x64  textures to 512x512 to avoid very blurry textures. This really isn't something I want to do a ton, since it's an extra workflow step and would probably carry that extra file size into my game. I'd really like it if there were more features to accommodate this use case. Increasing the scale helps a little, but the max size limit of 2 is not enough to get rid of all the interpolation bluriness for a 64x64 texture.
