Hey guys, I’m having a nightmare of a time attempting to play around with the free 4.4.3 mountain landscape project, in particular while building the lighting. Every time, it freezes my PC completely and immediately after the swarm loads, for up to an hour, and then returns an error.
The changes I have made are removing ALL actors from the scene aside from the atmospheric fog, directional light, landscape, music, windtrees, gizmoactiveactor and skysphere (which I set the material of to the default).
What I’ve added is a single spawn, the character+game mode from the FPS example project, a few basic platforms in the air, and a small lightmass volume around said platforms. Below is the error message I was returned in my most recent attempt at building the lighting:
Error <None> === Lightmass crashed: ===Unhandled Exception: 0x00000001

The cause is obviously the landscape’s massive size and detail, so what I’m requesting is suggestions as to how to lower the memory required for the lighting build. I’ve tried lowering the Max LOD Level to -1 and the static lighting resolution to 0.25, but this seemed to have little effect. I’m not concerned with preserving detail, so all suggestions are appreciated.
