Hello sp614x thankyou for the reply.
This is great news! So in theory the parameters could be added into the world class RadialFog shaderpack you provided a while back? This would be absolutely brilliant, the possibility of seeing the void fog back in Minecraft would be outstanding! So I guess it would even be possible to bring back the void particles also? In theory could a parameter be applied to player Y coordinate for the particles also? I hand on heart wish I knew how to apply the parameters, the only mention of any sort of void fog parameter is the depthsuspend quote from yourself on github.
May I ask for some of your valuable expertise regarding the player Y coordinate parameters to help out us old minecraft veterans? Eternally grateful for your time sp614x hope to speak soon.
