It seems to only work well in Cinematic mode in 5.2
In the video, you can see the hair drastically change at 1:24 when it is switched from Cinematic
There’s a cvar called r.HairStrands.SkyLighting.IntegrationType
On CInematic Scalability (Shading), it’s set to 1. On all others, it’s set to 2.
As one might expect for a Cinematic exclusive, it’s costly. But it’s the only way I can find to get Lumen + Skylight + Strands to play nice.
