2D URP Renderer

[josemendez]

I'm aware 2D lightning is not supported, but I'm just trying a little transparence, without any kind of refraction or reflection with fluids over 2D sprites. 

Opaque fluids are working nicely enough over sprites, but if it could only have a small transparence over sprites it would be perfect for my use case. 

When I try the standard universal URP, fluids become translucid and do not take any colors, also fluids when above spirte, even being translucid, make sprites completly vanish. 

Hi!

Make sure you've setup the fluid renderer feature for URP, otherwise fluids will be 100% transparent without any color just like you describe. See:

also fluids when above spirte, even being translucid, make sprites completly vanish. 

This is just due to how transparency works in realtime rendering: transparent objects must be rendered in a back-to-front order, otherwise objects rendered *after* reading from z-buffer will vanish. Depending on how your game is structured, this may or may not have a solution. For instance, if fluids can be simultaneously on top of and behind sprites, there's no solution since no drawing order can make an object be simultaneously in front of and behind some other.

kind regards,
