Hello, thank you for the response.
I’m on Unreal 5.5.4 and i don’t see “Hair Rendering” in Process Volume > Rendering Features > Hair Rendering, neither in project settings > rendering.
Our shadow map method is Shadow Maps, not Virtual Shadow Maps, as i noticed that VSM tank FPS in our game.
Also switching Light Channels on the hair groom doesn’t seem to do anything.
When i switch light channels on the spotlight - disable Light Channel 0 - the hair groom is no longer affected by light.
However, when i enable other light channels on the spotlight, while keeping light channel 0 disabled, the entire metahuman is no longer affected by that spotlight, even when channels 1 and 2 are enabled on the metahuman.
