Maybe a silly question but....

This may be a silly question but I searched and was not able to find anything. I dunno if I was using the wrong keywords maybe but I found no info on adding textures to the game.

I know we can replace them (Thank you Deirdre! ) but I am looking to add some new textures.

Can anyone enlighten me?

Thanks Yall!

Thanks red for the update. Love the new web/forum site btw!
