The box collision issue (where it would fit a box at an angle instead of what would best fit the shape) was fixed in the source build of UE5-main the last time I checked (which was admittedly a while ago). Everything else was still hopelessly broken and I never found solutions for them.
I also never got any clarification as to whether Chaos destruction was ever intended to be usable for environments that the player could move through.
I also discovered that Chaos geometry collections have no representation in the Lumen scene so they can’t get stable GI and can’t provide correct skylight shadowing. I posted about this in the Lumen thread asking if there were plans to address this, and again, never got an answer.
Chaos Destruction was still getting updates the last time I checked. They had added some new features including convex hull collision which might address the issue of navigating destructible areas… maybe. I couldn’t actually get it to work.
My advice would be to wait until 5.0 officially releases, I assume there will be a lot more information available then and the whole system will be more usable… maybe. If you have to make a decision now then I would personally not use it, because right now it barely works and there is basically no information on what the intended use cases are so it’s anyones guess if it will ever get better for your particular purposes.
