Thanks for the PR, I'll have a look at this this evening

As far as I can see it just disables SSRT for Voxy. Not sure what banding is being referenced here, but SSRT implementation in photon is overall very noisy without TAA.

See related issue that I posted (it has images) The banding is verry severe.

Thanks for submitting this sakari119 :)

What I meant is that it's nearly the same as disabling SSRT Shadows entirely. The PR disables it for voxy chunks. That isn't really a fix.

These are my results with default settings apart from: Disabled TAA, disabled all fog effects and changed overworld fog intensity to 0 and cloud shadows disabled, all settings to enhance clarity on the issue of this PR.
