Editor Crash on Static Mesh import into Actor

Hello,

I am trying to create a BlueprintActor that consists of ~10000 (ten-thausand) Static Meshes

(total Size of ~1.2 GB in UASSETs).

For this I am dragging the Static Meshes from the Content Browser into the Actor Blueprint Viewport.

Up to ~5000 (five-thausand) works, but trying to get over that sometimes causes the Editor to Crash.

Going over ~7000 (seven-thausand) always causes the Editor to Crash:

(All at once or a few hundreds/thausands one after another does not make a difference)

LogWindows:Error: === Critical error: ===

LogWindows:Error:

LogWindows:Error: Fatal error!

LogWindows:Error:

LogWindows:Error: Unhandled Exception: EXCEPTION_STACK_OVERFLOW

This must be some kind of Error of the Editor (maybe some inefficient Loading of the Static Meshes?),

it shouldn’t be caused/limited by the Hardware: NVIDIA Quadro M6000, Intel Xeon E5 2650 and 256GB RAM.

(I am on 4.16.1, Windows 64Bit)

Has anyone insight on why this is happening and maybe on how to fix it?

(without having to wait for an Engine Update)

Thanks :slight_smile:
