Following up with a visual example.
The material instance is created correctly and I have some parameters with my vex along side. Why doesn't this work like it's quoted in the docs?

"To change a custom My Color Vector parameter that you created in your material, add a unreal_material_parameter_mycolor detail attribute, Float with a tuple size of 4, and set its value to the desired color value, ( 1.0, 0.0, 0.0, 1.0 ) for a bright red"

Works fine for me without Session Sync when using spline actor in the World Input of the HDA.

Is anyone having trouble getting material instance parameters working? Wondering if this is a user error or a bug.

I'm following the documentation, but can't get the "unreal_material_parameter_diffuseboost" param values to transfer over like in the example. My material instance is being created fine, however.
