Mantaflow - fluid does not render but renders related particles
Closed, ResolvedPublicBUG


System Information
Operating system: Windows 10 Home, Version 10.0.18363 Build 18363

Graphics card: ASUS R9 290X DirectCU II OC

Blender Version
Broken: V2.82 Alpha, ed32db06c124, 2019-12-16, as found on the splash screen
Worked: (optional)

The scene is a water cube and an icosphere is moved in a linear fashion on the surface to generate waves and related bubbles. Water domain does not render but shows in the viewport in any view mode when water layer set not visible. If the water layer set visible then it shows the cube for the water and not the domain and no waves are visible and only the bubble, foam and float particles show in render window without water and generated wave. Used GPU and CPU renders but both gave the same results.

Exact steps for others to reproduce the error
Bake the attached file and render after disabling the visibility of the water layer.

Hi! Did you enable "Show Emitter" in the Render panel in the Particle Properties? That should be enabled if you try to render both the domain mesh and secondary particles (see screenshot).

Hope I understood the question correctly, otherwise, can you go a bit more in detail? And also, please use a more recent build. Thanks!

Hi sebbas,

I downloaded the latest build and ticked the "Show Emitter" and that fixed the problem. Now it renders the liquid as well as the particles in the render window.
I do not recall unticking the "Show Emitter" box though. Is that turned off by default?

Ok perfect! I think it should be on by default. If you notice it turning off through a combination of settings, just let me know. It should definitely be on.
