Heh, well, I have no proper knownledge of the actual limitations, like how often you can call BP nodes so this all is highly experimental. To be honest, I was surprised that it even worked in the first place. Did you get the crash with draw debug trace setting on or without it? Because if it’s on, it’s almost expected to crash as some point. I kinda put that setting just to test it, but in real project you should do your own debug draws from tick instead.

I tried with that debug draw off, 16 substeps, max substep delta time at 0.005 (so set to calculate physics 200 times in a second) and maxFPS at 10. I couldn’t get it crash here. Can you tell where in the engine it crashed?

I’m now wrapping this whole thing into a plugin so it can work in BP only projects. Found an interesting bug, when you enable sub-stepping and have a component in hierarchy which calls a normal Tick() event it crashes. I’ve reproduced bug using your code - as you more familiar with it.

If you delete Tick() event from TestComponent (delete from the BP graph), then everything is working fine.

I’m not sure what is going on, perhaps component’s Tick() is invoking the same function in the pawn class. I could submit this as bug report but I’m not sure if Epic’s stuff is going to look at it as it’s a custom C++ code…
