how can i get a material instance’s metallic by blueprint?

I think the only way to get material info via blueprint is by using the “GetScalarParameterValue”, “GetVectorParameterValue”, and “GetTextureParameterValue” nodes.

If the material instance’s metallic input is either a Scalar, Vector, or Texture parameter, you can use one of the above nodes to get the needed value.
