No worries. I don't mind figuring stuff like this out on my own anyway.
I did actually check the dithering images page, I just never noticed the link to the one for Photoshop. 😅
The only thing I can't figure out right now is how to make glass. I even opened glass walls from the game in the object editor, but still couldn't find how it's done.
Also sometimes I get a stream read error when trying to load images into the Object Editor, not sure what causes that.
