Decal facing the right way

Hello guys!

I am thinking how to make something like paintball gun, but i dont know how to start!

I mean… All I want to know about is just shooting at the wall and then it shoud create the decal for example like in game called portal.
I know how to do all of this stuff but, I have no idea how to make a decal face the right way. I hope you will understand that!

How does your gun shoot? Are you using physics or are you using something like FastCast?

The issue with the Roblox paintball gun is it is not currently retrofitted to support FE yet. This will need to be done manually.
