ObiFluidRendererFeature is still in preview, only compatible with LWRP and early URP versions. We do have full URP support in 5.5, which is still in beta. I can send you the relevant files if you wish, just write to support(at)virtualmethodstudio.com.

cheers,

Also: are you running one of the sample scenes, or a scene of your own? If it's one of your own, can you describe/post your setup?

delete DerivedData and clean project, it's same. I can't build

This means you need to use Obi 5.1, 5.2, or 5.4. I'm sending 5.4 to you.

Once I check Obi particle renderer/ Render, it shows.

https://prnt.sc/tkwe9k

Quote:Most modern mobile GPUs actually only support either 32-bit numbers (used for float type) or 16-bit numbers (used for both half and fixed types). All PC GPUs that support Direct3D 10 support very well-specified IEEE 754 floating point standard. Mobile GPUs can have slightly different levels of support.

Check if your platform supports high-precision (floating point) textures. If it doesn't (which is very strange, as most modern GPUs do, even mobile ones), you can replace the sampler2D_float declaration in Obi/Resources/ObiMaterials/URP/ObiFluidsURP.cginc with sampler2D. That will fix it. From Unity's docs:



By deleting the shaders, the fluid renderer will no longer work. They are needed for fluid to be rendered at all.



This is of course due to the fact that you simply deleted the shaders used to render the fluid. You can't delete required files and expect things to still work.

After I replace the sampler2d_float with sampler2D,
On PC
 -  it works as well (I didn't test on device, just fine on Editor)

On Mac
 - it's not works.  I have to check Render option in Obi Particle Renderer to see fluids.
 - come back to same scene, fluid is not appear in first time

Mac is our primary development platform, we develop there and then test in all other platforms. We could not reproduce any issues in mac. If using reflection/refraction in the renderer feature, make sure to enable depth and opaque texture generation in your pipeline asset.

Let me know if the issue persists.

WHAT IS THIS??!!
