sonofa… okay my bad. Unless you consider that maybe keeping collisions should be a given. The Merge Physics Data IS the collision data. I’m still not clear why some of my models show the collisions but still don’t work. I’ve tried pushing this with lots of merged things and by spreading out the merged things and haven’t been able to get it to break today.
but i’m keeping an eye on you merge data, and maybe from now on will not autoselect REPLACE SOURCE ACTORS…
so to be clear, Merge Physics Data is NOT
checked as a default. I think it should be, because why would you build things and not want the colliders?
