The title kind of explains it all and all the detail are in this video.
The Paint Tool doesn’t work on world models such as buildings and the ground.
It works on Ragdolls and props, but there are limitations.
Sent a message to help and support on Garry’s Mod, but there was no reply.
I even sent a video reply to Garry himself. Is there anyway to fix these problems?
This video will be removed when the problem is resolved.
