4.12 Lighting issue

I have transferred my project to 4.12, and after light rebuild in my level, I have noticed a strange artifact on all my lights. It looks like a light burn of some sort, a black hole if you might. I don’t know what it is or what is causing it. But I did take notice that changing the source length has a en effect on it. Or completely goes away if I check off ‘use inverse squared falloff’.

Your wisdom on the matter would be most kind.

Hi Antoine,

This has previously been reported with UE-29543 and has been fixed internally already. The fix will be officially in 4.13 once that releases.

However, you can fix this yourself without need to recompile source code or know any coding. Just follow the steps in this post for the workaround: Point light causes black void (Source length) - Rendering - Epic Developer Community Forums

Once you fix this and restart the editor the shaders will recompile and you’ll be set!

I hope this helps.

That worked great, thank you so much for your response.
