Lumen GI and Reflections feedback thread

I would like to know if fixes are planned for bad shadows with Foliage Nanite and Ray Tracing Shadows. For the shadows cast on the ground I don’t think there is a solution for the moment, I tried with Fallback Error 0.0 but the crown of the tree loses all the brightness and the scene becomes heavy.
For bad shadows on the trunk I tried with the commands:
r.Raytracing.Shadows.EnableTwoSidedGeometry 0 but is ineffective
r.RayTracing.NormalBias 5 solves shadows on the trunk but removes shadows on grass leaves.

The scene without Ray Tracing Shadows is clearly much slower.
