Problem with particle shader

Phoenix Issues
1

Hi,
I have a problem with the particle shader
Some bubbles are outside of my PhoenixFD Liquid and I can’t get them inside
Do you have an idea please?
Thanks for your help​

Hello,

The bubbles if they are splashes or foam can live outside of the liquid so it’s totally possible for them to be separate.

Can you show us a screenshot of how your simulation looks like?

Hi Georgi,
Thanks a lot for your reply
It’s a small scale liquid simulation and you can clearly see the color of the bubble outside the liquid mesh on the screenshot
I don’t know how to remove them or fit them into the surface

The easiest way to fix this in your scene would be to go to the Particle Shader options and change the Subgroup setting to Under Water. This way only particles inside the mesh volume of the connected Liquid Simulator will be shaded.
Note that when Mode is set to Splashes, particles will not render with the Under Water subgroup as it would produce no effect to render liquid drops submerged in the liquid surface.

Hi Georgi,
I tried the different options and also the subgroups and I still have the same problem.
you can see in the attachment that the bubbles on the outside of the surface are transparent while those on the inside are yellow\orange
thanks for your help

Ah, then - let’s try something else.

Select the Simulator node and go to the Rendering rollout > Mesh and change the type to Maya mesh.

Go to the Maya Outliner and in its Display settings enable the checkbox for “Shapes”. Still in the Outliner press the plus icon next to the Simulator name.
Select the node that is called something like “PhoenixLiquidSimulator1Mesh_0”, with it selected, Ctrl+Select the Particle Shader.

From the Particle Shader settings - make sure the Use Cutter checkbox is selected and then press the button “Use Selected Object as Render Cutter”. This will use the liquid mesh as render cutter and will render only the bubbles that are inside of the mesh.

Hi Georgi
Thanks for your reply

Sorry if I didn’t tell you but I’m on 3dsmax​

I added the fluid to the cutter geometry on the particle shader panel and now it works!!
It’s strange because I already tried that but it didn’t work.
Thanks a lot for your help

Sorry - for some reason I decided you’re using Maya - totally my bad.

For 3ds Max it’s a lot easier - just pick the Simulator as a Cutter Geometry in the Particle Shader options and that’s it.

Cheers!
