Texture Sample Parameters cause error when used in Make Material Attributes Material Function

Texture Sample Parameters cause error when used in Make Material Attributes Material Function

Developer Notes

Not a bug.

If you convert a texture sample to a parameter it requires that you set the Texture property.
This is the "Requires Texture2D" error.
Adding the make materials attributes node simple reports that there was an error on the incoming base color pin.
