The project does use quite few alembic files imported as a skeletal mesh. The app is crashing every second, third attempt when trying to open the level from main menu. So, the crashes are inconsistent, I mean it doesn’t happen always.
I’ve been digging through the source code, but found nothing that would bring me closer to a solution. Crashes stopped when all of the alembic files were removed from either the scene and content browser, however I need to keep those in the project.
Would appreciate any guidelines as to what huge delta means in this case, would it be different vert count between base_0_0 and the next in hierarchy ? Too big vert count on each morph target or something else.
