Hello
How to make Niagara particles white like steam?!
I have minimal experience with Niagara, but really enjoying it so far however…
i have created a 3D Gas sim usning the Grid 3D Gas Master emitter template , basically out-of -the-box. The only thing I want to do at this point is make the sim white like steam. I’ve been digging through the documentation, default material and instance but can’t , for the life of me, find a way to make the particles render as pure-ish white - only the mid grey that is the default (in preview window and viewport). I can change ‘render color -smoke color’, but it is already set to white.
3D Gas sims can obviously have very complicated materials for rendering various elements (temperature, density, velocity etc), however i just wan to render the particles as white.
Any help on this would be greatly appreciated… hopefully easy for someone familiar with this system!
Cheers
Corey
Hello there @coreymurray! Let’s try to figure this one out.
Please try the following steps to alter the smoke color for the emitter:
-
Expand the Lights section, and the extra options beneath it
-
There should be two nodes called Lgt1 and Lgt2 Defaults, which control what the smoke looks like (as long as you don’t have anything else connected in the scene)
-
Adjust the settings for your desired effect. You can control color, intensity, light direction, and shadow density
Hi brs-sebascova and thanks for your reply.
I can’t see any lights in the emitter settings:
Could you show where those light settings are?
In any case won’t that just be in the preview? The sim will end up in a map with lighting - will that conflict? Also wondering what happens if you make it white?
My main goal is to create white particles, so the sim looks like dense steam.
Cheers

Hello again @coreymurray!
You are correct, checking the latest UE version, master emitter seems to have been reworked, so this method won’t do anymore, apologizes for that.
Let’s try a different approach, I would suggest starting new, and following the community guide for creating a steam emitter from scratch, as seen here:
https://dev.epicgames.com/documentation/en-us/unreal-engine/how-to-create-a-steam-effect-in-niagara-for-unreal-engine?application_version=5.2
Additionally, here’s an alternative quick method for thin steam:
Thanks again for the reply.
I went trough those videos and they are really handy, but don’t address the core issue of creating a material to render VDB/Particles as pure white steam. I’m wondering whether a simple material could work… from what i understand, steam appears white due to its light-scattering properties not emitting light as per fire or plasma.
