Hi,
I am reporting 2 rendering bugs for Obi Fluid on iOS.
Unity 2022.3.60
URP or SRP
iOS v18.3.2
iOS SDK: 18.2
Obi Fluid [7.0.5]
Solver backend: Compute (GPU) and Burst(CPU)
Test scene: FluidViscosity
When running on iOS,
1. test scene with Burst backend, there is a black color issue in the transparent fluid rendering (same bug in SRP or URP), see screenshot 20250314_135736000_iOS.png
2. test scene with Compute backend, fluid rendering starts with the same look as Burst and with same black color bug but after 2 or 3 seconds, the fluid mesh explodes, see screenshot 20250314_140447000_iOS.png
I built on PC (DX11) and Meta Quest (Vulkan), and the rendering presents no bug at all : com.oculus.vrshell-20250314-153625.jpg
So, seems to be an issue with Metal API...
Hope this helps !
