I found the culprit, seems like a bug in Unity. Turns out the camera depth texture accessible to the shaders isn't cleared to the correct value in OpenGLES unless the camera is explicitly told to render a depth texture. I will raise a bug report.

Found out that I had a regular (deactivated) FluidRenderer attached to the camera. The presence of this renderer set the camera depthTextureMode, so the SimpleFluidRenderer worked well.

Removing the FluidRenderer allowed me to reproduce the issue.

Simply adding this line to the SimpleFluidRenderer's Setup() method fixes it:

Code:

GetComponent<Camera>().depthTextureMode |= DepthTextureMode.Depth;

Attaching the updated SimpleFluidRenderer for convenience.

I don't understand the question of 2 SimpleFluid... what do you mean by "connecting"?

Why do you have 3 fluid renderers, instead of having just one that references the 3 particle renderers? That's extremely costly. There's a reason why the fluid renderer accepts an array of particle renderers as input, to render them all at once. See the FluidBuoyancy sample scene.

(17-12-2019, 08:53 AM)josemendez Wrote: Particle colors are set in the ParticleRenderer and/or the emitter shape, not the FluidRenderer. You can still have one FluidRenderer and have particles of multiple colors.

Using a separate FluidRenderer for each fluid not only is extremely costly (3-5 full screen buffers are used for each fluid renderer), it also serves no purpose at all.
