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: CFrame.new(ray.Position, 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?

try CFrame.new(ray.Position, ray.Position + ray.Normal) * CFrame.Angles(math.rad(-90), 0, 0)
