i have the same issue too

can also confirm this with any non-vanilla fluid

Can confirm

Can confirm as well

Can confirm as well. Looking in the meltery, fluids DO render. but are extremely transparent. Only difference was a change of tint on the blocks behind the meltery.

Running Oculus, Rubidium and TC on a 12900k, and a 970. Using Astralux Shaders, but tested with Sildurs, Complementary, Sora, and others.

Issue solved. I found a fix but it will remove the animations for fluids.

It is a workaround, but not a solution. It is generally preferred that it be fixed on Oculus' end.

Locate the file in the config folder: tconstruct-client.toml
change TankFluidMode = false to true

Upstream iris 1.3.0 fixes this (for the fabric port, so it'd probably work on oculus/TiC forge too)
