For the MtlxStandardSurface, under the "transmission" tab...
So depth does work (we call it "absorption"). But one gotcha is the automatic-fake-caustics (ie transparent shadows) can reduce the effect. One possibility is to disable it, or to tweak the "Fake Caustics Opacity" setting. The attached example shows depth/absorption working with fake caustics disabled.
- these 5 work: "transmission", "color", "depth", "dispersion" and "roughness"
- these 2 do nothing: "scatter", "anisotropy"
