Question by Kpt-Offensichtlich · Jun 03, 2020 at 08:10 AM · shadersruntime

Property of VFX graph changed by script seems to change value but it does not show in inspector or scene.

Hey fellow VFX-Friends,

I am trying to change some Property values via a script. The code I use is here:

     public void Awake()
     {
         _connecterEffect = gameObject.GetComponent<VisualEffect>();
     }

AND

 public Vector3 IntermediateOne
 {
     get { return _intermediateOne; }
     set
     {
         Debug.Log(String.Format("We grab the value: {0}", _connecterEffect.GetVector3("IntermediateOne")));
 
         _intermediateOne = value;
         _connecterEffect.SetVector3("IntermediateOne", value);
 
         Debug.Log(String.Format("After SET we get the value: {0}", _connecterEffect.GetVector3("IntermediateOne")));
     }
 }
 

What is surprising is that in the second _connecterEffect.GetVector3(...) I indeed get the correct value. But it does not show in the inspector, nor does the VFX-Graph change its behaviour accordingly.

Edit: By "show in the inspector" I mean, the exposed properties of the VFX graph do not change.

Help would be greatly appreciated.

@Kpt-Offensichtlich Firstly Please don't write many things on the same line of the code. If it ends with ';' it means new line should start, and not continue on the same one.

Secondly, I don't really get what is your problem? Like if you want to see the value of the Property in the inspector than Unity doesn't have that kind of stuff (of course you can always write your own Editor) And If you want to see "_intermediateOne" in the inspector make it public or write [SerializeField] in front.

@N$$anonymous$$J_GD Thank you for the response. I am not sure why it is that terribly formatted. It looks way better in edit mode.

The problem is, that although the value is changed like it should, the Shader does not behave like the value changed.

And I can see the properties of the shader in the Editor. I didn't mean the properties of the script. Sorry, that was not so well formulated
