Physics Mod Pro V69 - Smoke Shadow Support

Ok I just scratched the monday release and decided to release the shadow support immediately (you need to set the shaderpack that you are using in "Physics Settings" > "Smoke Settings" > "Shadows" to enable smoke shadows). Reason being is that I need feedback on which future shaderpacks should receive smoke shadow support. Please leave the shaderpack names in the comments!

TESTED SHADERS: Complementary Shaders 4.4, BSL 8.1.01, SEUS Renewed 1.0.1, Sildurs Vibrant Shaders 1.31 Medium.

IMPORTANT Smoke Physics Information: Minecraft particles have to be enabled for it to work! The further away you are from smoke sources the less particles spawn. Temporal Anti-Aliasing (or TAA) can cause issues with the smoke so disabling it will eliminate some visual artifacts. Not all shaders are supported (best results that I've got are with BSL shaders).

IMPORTANT Snow Physics Information: Optifine is not supported (use Iris + Sodium on Fabric/Oculus + Rubidium on Forge). High render distances on slow CPUs might result in delayed snow tracks.
