Set different Colors across instances via script

Quick Scenario, I want 10 different explosions on screen, each with a different color and slightly different values for exposed properties in my VFX graph.

Coming from ShaderGraph, I know how to dynamically assign different colors using MaterialBlock.SetColor

How do I do that in VFXgraph? There's a code example in the docs for eventAttributes, but not properties.

There's also no SetColor, so I'm assuming we should use SetVector4(property,value)???

Also, when working with multiple cloned instances , it's odd that group editing does not allow toggling all the properties.

 

You would create a color parameter that is exposed. Pipe that parameter to set color in the update particle block. Then in your C# script you would change that color via VisualEffect.SetColor("ParamName",[value])

 

Coming from ShaderGraph that was my initial guess too. Unless there's a new version, VisualEffect.SetColor does not exist which is why I wanted to confirm in the forums.

https://docs.unity3d.com/Packages/com.unity.visualeffectgraph@7.3/manual/ComponentAPI.html

VisualEffect.SetVector4 does exist and I can confirm it can be used to pass colors to exposed parameters in the VFXgraph blackboard.

 

Sorry I see your issue. Yeah you're right, vector4 should set the color.
