Blender USD export -Remove Scope from resulting material network #33

Closed philip-luk-tangent-anim closed 3 years ago

philip-luk-tangent-anim commented 3 years ago

Blender usd export currently export material networks with a scope within the material itself.

This causes issues when trying to edit these materials in houdini.

Houdini 'Edit_Materials' is not handling complex material networks or image_texture inputs upon being edited.

Networks with more than one closure fail to rebuild. Image_texture nodes fail to find their material path. They work again when set to 'set or create'

Let the material fully encapsulate the cycles shader without using a scope.
