EDIT: Answer posted. Hello, I have a projectile that I have made stick to walls, currently behaving like the Medic’s needles from TF2 (sticking to walls at any angle it hits). I would like to change it so that it will be perpendicular to the surface, AKA aligning to the surface normal rotation. …

I’ve found the solution to calculating the angle of impact in blueprint, so I thought I’d come back here and post it for anybody who finds this question. theta(angle between vectors a & b) = acos( dot(a,b) ) [13361-angleofimpact.jpg] So here I use a Dot Product node, and input the forward vector…

How can I get the surface normal's rotation in collision?
