Question Is there any way to change material properties of a VFX Graph that uses a Shader Graph?

Using Unity 2022.1.24f1

A have a VFX Graph that uses a Shader Graph, during runtime I want to reference the material it's using to enable / disable the Cast Shadows option:

I tried assigning this material:

material.SetFloat("_CastShadows", 0);

I can see the material changes in the inspector, but the shadows still get cast, so the VFX Graph must be using an instance of that material, but how do I get that instance?

 

I'm exactly in in your situation now and still searching for that material instance >.<
I want to use "material.SetBuffer" for the shadergraph material. As I'm using the shaders Setup() function to do some stuff.

 

Okay, found it. On the gameobject with the VisualEffect component, just do the following:
GetComponent<Renderer>().material
As the VisualEffect component also adds the renderer component. And this has the material instance.
