Hi, I m struggling with some dark spot on my grass with lumen, I can’t find what could cause this do you have a idea ?
Hi gachealexandre,
Try converting the grass to Nanite - or remove the last LOD of the grass - that last LOD is a billboard.
Another option I’ve seen people do is to change the material on that last LOD to same as the previous LOD (not the billboard LOD).
Hi thanks for your answer, i sadly already deleted all LOD on the grass 
and is converted to nanite already too
