hey,
how can i fix these jagged shadows on Groom?
UE 5.2.1 + Lumen + PPLL Alembic Groom + no Direct Light
Direct shadowing is generally not a lumen matter as much as whatever your preferred shadowing method is. When you say no direct light, do you mean it’s all being lit with an emissive?
If so, that’s probably your first problem. Lumen can’t really do fine geometry too well, so I would first replace whatever you have with a rect light using RT shadows, and see what that gives you.
