Help using vertex offset

Postby noeinz » Wed Jan 09, 2019 3:07 pm

Hello Amplify,

I have a shader here that is supposed to collapse towards a reference point, like a worm hole. So far I have the vertex offset pulling towards the point properly and the collapse happens but the numbers go beyond 1 and it starts inverting the collapse of the mesh. I cannot figure out how to collapse towards the object and stay collapsed without inverting.

Here is my node setup

I am trying to recreate this shader from this post:

Hello, thank you for getting in touch and for your support!

The example you posted roughly translates to this:

Image

The float values will have to be tweaked specifically for Unity, and the _Position global variable is receiving the transform position of the orbiting sphere through a script that is attached to it:

Code: Select all
[ExecuteInEditMode]
public class Test : MonoBehaviour
{
    public Renderer Renderer = null;

    private Material m_instancedMaterial;
    private Material InstancedMaterial
    {
        get { return m_instancedMaterial; }
        set { m_instancedMaterial = value; }
    }

    private void Awake()
    {
        InstancedMaterial = Renderer.material;
    }

    // Update is called once per frame
    void Update()
    {
        InstancedMaterial.SetVector("_Position", transform.position);
    }
}


On the Renderer parameter in the inspector of this script you'll have to drag the other sphere, which has the shader assigned to it.

Thank you so much. It works! :mrgreen:

I feel like I had this answer but I missed some combination in my setup. Maybe I had the nodes hooked up wrong in the lerp.
