shadow.enabled

shadow.enabled=<true|false>

Location: shaders.properties

Normally Optifine/Iris will check if the shadow buffers are bound and used to determine when to enable/disable the shadow pass. Iris offers an additional explicit control for enabling/disabling the pass. Thic can be useful for voxelization which doesn’t write to a shadowtex/shadowcolor buffer (for example SSBOs or custom images).
