Hello everyone!
Look like a got a bug when importing meshes from UE4 to an HDA using Object Merge nodes.
I made something really simple to reproduce the crash.
Made an HDA with just a curve input, a resample node and a copy-to-points from an Object Merge.

So now when I import the HDA into UE4 I do the following:
- set Curve as Input and draw a simple curve
- Assign a mesh (from FBX) to the object merge -> things look ok
- Change the input mesh SLOWLY a couple of times (box1->box2, box2->box1, box1->box2 etc.)

UE4 crashes here everytime when switching out the meshes. Mostly after the 3rd switch.
As for the meshes i just made 2 simple boxes in Modo. Nothing fancy (to be sure there's no broken geo).

It can't get simpler than that and I still got crashes all the time. I attached the hda and the 2 boxes as FBX.
Any idea what could go wrong here?


Thanks in advance!
Best,
ron
