Training Livestream - Pawn Movement Techniques - Oct 4th - Live From Epic HQ

I know this stream is quite old, but could you point out some ways to make the physics on each zombie impact less the performance? Another question as well, how can i make physics animation only affect when there is an object blocking its animation(Not just impact of gravity or inertia)?

I know this was 2 years ago but the sample project doesn’t seem to open with 4.17 or 4.19… Any tips?
