Larian Studios Forums Divinity: Original Sin 2 - The Modding Dungeon Divinity - Original Sin 2 - Modding General How do I paint surfaces on objects?

What the titel says.
How do i paint surfaces to objects? water, fire, ice and so forth.
I want to cover a stair with ice but can't figure out how to do it.
Anyone?

You should be able to paint surfaces on anything that's set to Walk On, has (green) AIgrid over it, and can Receive Decals.

silly me... of course. Thanks
