It doesn't work gor all type of logs, like acacia, full logs or else.

Could you please be a little more descriptive than that? Which version of minecraft are you using, do you have any other resourcepacks, did you put Round Trees on top of all the other packs?

@Motschen 1.16.3. I have other resourcepacks, better leaves is only above that.

@Motschen with round trees only same problem. I'm talkig about full logs that has textures on every side.

Oh, you mean bark blocks.
That's out of the scope of this resourcepack.
Old versions of the pack altered the bark blocks, but it was generally disliked, so I removed it.

@Motschen that's understandable. So I think everything works, thanks! :)
