Bug / Crash Obi Fluid 7 Transparent Fluid has no color

[hariedo]

That's why I feel like I must repeat the same advice, even if I risk sounding like a broken record.

My guess is that you haven't added the ObiFluidRenderingPass to your ObiFluidRendererFeature. Even if you use stock assets, this step is necessary for the URP renderer (which is not a part of Obi, so you cannot use a stock one!) to provide the necessary buffers for transparent fluids to work as explained in the manual, see the bit circled in yellow:

Apologies for sounding uncivil above. This setup is kinda ridiculous, to be honest. Add feature. Add pass so that PART of the feature works. But we got there.

I dunno, having some part of the Feature spit out an error if there are zero passes might help. Having some part of the Mesher spit out an error if there's no Feature might help. Having a "helpful tip" of "hey, if you get clear water" in the manual might help. Replacing my brain might help.
