Access to game textures

Hey Besiegers!

I am working on some new blocks and it would be nice to use the wood and cloth textures from the game. How can I get those files or does Besiege's licensing restrict that? Thanks.

Actually most of the mod devs already have access to the files, if you would like to join the chat client that the modders use send a message to spaar, we can about the files there.
