Hi Obi,

it seems that the fluid transparency in URP is not working. When you compare the built-in pipeline at the video start we can clearly see the checker pattern through the fluid. At the video end in URP the fluid is opaque. I am using the latest LTS 2020.3.4f1 with default URP packages. I also tried in new URP project but same thing. Is this a bug / overlook or I am missing something in the URP setup.

Thanks!

Hi!

Make sure you've enabled the "Opaque" and "Depth" texture buffers in your URP pipeline asset:

This is also shown in the setup video:


Specifically, without an available opaque buffer refraction/transparency won't work (as there's nothing to refract!) Sonrisa

Thank you Jose and apologies for not spotting this in the manual. However, I have experienced one more problem with fluid rendering in URP when I have got a transparent object in front of the fluid (see here red spere). My use case is to render a fluid inside humans eye so underneath transparent cornea tissue. In built-in that worked perfectly fine. Thanks
