I’ve ******* many issues on my UE4 scene.
As you can see, a lot of light leaks, and I don’t know why. I tried to unfold the lightmap channel 50 differents ways, without results.
I tried too change lightmap resolution ( 512 / 1024 / 2048, boost World settings, production mode etc…)
Initially, it’s Vray scene, but I adapted it to Unreal…
I’m out of idea…Do you have it ?
