Rethinking Voxels shadows issue

[RecRivenVI]

When using Rethinking Voxels, things that rendered using Flywheel cannot cast shadows, can this possibly be fixed? Without Flywheel compat(disable flywheel backend) its normal.

Using mods/shaderpacks: -Create 0.5.1.h -Embeddium 0.3.31 -Oculus 1.7.0 -Oculus Flywheel Compat 1.1.3 -rethinking-voxels_r0.1-beta5 (should be reproducible on most other versions)
