idk anything about making mods and workshop item wouldnt change anything cuz you still need to edit xml file

Can you make a workshop item or mod for easy use?

Ill give it a go tn

@Brooke7125 Yes? I think you can try

Can I use this method to paint the back of a block instead of a side? Trying to build a flag

Ok so for people who are having troubles like LeviOz heres how I fixed it.
With Step 4 of XML the invisible block make sure the 1 value is on the same face as the red block. Its hard to explain but the way to find out what that axis is is to do this:
Put a value of 3 into one of the 3 numbers (Should look like this r="1,0,0,0,0,1,0,-1,0" then to r="1,0,0,0,0,3,0,-1,0"
If you don't see the block stretching into the red side change it back to 1 and try another number
Once you have the right one go back and turn the other 1s into 0s and change the 3 back to 1 so say that 3 was right it should be r="0,0,0,0,0,1,0,-0,0"
This should work I was struggling with it at first but tried this way and it worked.
Hoped this helped

I think you didn't save it before editing, idk

I've done steps 1-3 after which I placed down a cube on the red side. Red side disappears, I go into the xml file to change the scale of that block to the one you've posted in your guide and when I reload the file, the block is indeed gone but the red side is back.

Could you tell me where it went wrong? Appreciate the help.

still works, you are doing something wrong

This unfortunately doesn't seem to work anymore. It does remove the side when I place the block on it, but making it invisible using the xml file just brings back the side of the paintable sign.
