How to set SpriteRenderer color using Material Property Block?

Unity Engine

I’m trying to set a Sprite Renderers color using MaterialPropertyBlocks.
Can’t get it to work though. I don’t want to set the color property on the sprite, since I’m only wanting to change the final color in Edit mode for some visualization.

I thought this might work:

[ExecuteAlways]
[RequireComponent(typeof(SpriteRenderer))]
public class SpriteRendererViz : MonoBehaviour {

#if UNITY_EDITOR
    [System.NonSerialized] private MaterialPropertyBlock mpb = default;

    private void OnWillRenderObject() {

        if (Application.isPlaying) {

            return;
        }

        SpriteRenderer renderer = GetComponent<SpriteRenderer>();

        if (mpb == null) {

            mpb = new MaterialPropertyBlock();
        }          

        renderer.GetPropertyBlock(mpb);

        mpb.SetColor("_BaseColor", Color.green);
        mpb.SetColor("_Color", Color.green);
        mpb.SetColor("_RendererColor", Color.green);
        mpb.SetColor("_FillColor", Color.green);

        renderer.SetPropertyBlock(mpb);
    }
#endif
}

But nothing changes.
The code does execute correctly in edit mode. Just no color changes are applied.

Using URP 8.2.0 2D Renderer

Is it even possible to change the color of a SpriteRenderer using MaterialPropertyBlocks?

mpb.SetColor(“_Color”, Color.green); Works in built-in renderer, but not in URP :frowning:

Ok, turns out SpriteLitDefault has no color property on the shader like the built in Sprite shader does.
Fixed with a custom shader.
