High Speed Collisions in 5.4

Hi, I’m trying to do some flight collisions. What’s the best way?

I’m using the open world and the 3rd person pawn.
Collisions are working while walking and 80% of landings. 20% fall through.
I’m building simplified physics and using movement mode none while flying.
The pawn is flying around 1200 cm/s

I’ve tried CCD (helped) and MACD (???), but the landings aren’t 100%.

To get 100%, I have to blow up the 3rdPerson’s capsule to 100x300 cm, which is too big. The pawn collides, stops forward movement, then falls 0-300cm. Not great. Also, my computer is too fast, so it may suck on older hardware.

What’s the best way to get flying collision?

I saw something about doing ray tracing or maybe a thrown ball like in VR.

I feel like I’m missing something that’s already built…

Thank you!
