Just started using Asset Forge today, and I have to say that I am very impressed. Well done!
I played around with it and was wondering if I could add other textures to use with the existing blocks?
I tried pasting a texture in a new folder inside the Collections folder but it didn't show up on restart (but I can see the folder name appearing as a group of blocks).
I am using AF 1.3 deluxe on Mac.
