Lighting build failing "Array Index out of Bounds"
I upgraded to Unreal 4.7, and while I was doing a lighting build, I ran into some lighting build errors saying lightmass crashed array index out of bounds. Its only happening on adding certain static meshes and not all. I have looked the properties of meshes that work and meshes that don't, and there is no difference. Can anyone help in figuring out what is wrong with these meshes? This is really urgent!
Did you ever get this sorted?
Often with Lightmass there can be several different reasons for the errors that come up. At the moment I'm in the process of getting a general troubleshooting and tips guide up for lightmass on our Wiki here: wiki.unrealengine.com/LightingTroubleshootingGuide
It's still at least a week out before it'll be up though.
Some of the common things that can cause Lightmass to crash are:
If this is a specific mesh causing lightmass to crash when in only included in the scene I'd be interested in having a look at the asset if possible. I've not run across that specific issue.
Let me know.
