How would I make a part rotate on another part?

Hello, I’m trying to make a realistic blood system but the problem is I don’t know how to make blood stick to walls.

I want blood to be rotated accordingly so it looks like it stuck to a wall.

Thanks for reading.

Use a raycast to define the normal angle. I dont know what to do with that tho, so your gonna need some more research about that


Search for ‘bullet hole on surface’. There are a few posts about it.


So I have found this:, ray.Position + ray.Normal)
It almost works.
Its just opposite of what it should do.
On the wall its pointing up and on the ground its pointing right.
Can anyone help me fix this?
