Datasmith in UE5.3 and 5.4 has import / visualization errors for cylindrical objects:
It’s supposed that 21 cylinders should be visible above, but only on the right hand side is visible. Left hand side has issues, when the length/diameter-ratio exceeds a certain value.
I already filed bug reports to this topic (e.g. case 00628122), but never received any follow-up, so i want to try it here.
UE5.2 and before just work fine for the same CAD input file.
