Lightmass crash 4.7

dorklord_666 · February 26, 2015, 8:36pm

Building lighting is leading to a Lightmass Crash after a minute or so.

This happens in the most basic scene on UE4 template. There’s nothing going on besides starter objects.

Never happened before on 4.6.1.

Same I didn’t get this before either.

I have moved this into the Bug Reports section for further investigation. A support technician will look into this as soon as able.

Cheers

I had this exact problem, and found a fix. Go to C:\UsersYourUsername\AppData\Local\UnrealEngine[Your Engine Version]\Saved\Swarm\ and delete the SwarmCache folder.

After this, you can re-launch your project and build the lighting.
