Rodolfo Ribeiro Gomes 4fcb0d036c fix default glTF metallic & roughness factor values
The glTF 2.0 spec says that these pbrMetallicRoughness material
properties should be set as 1.0 by default.
In fact, KhronosGroup's official Blender Exporter does not even write
down those parameters if they are set as 1.0.

However, Godot import them as 0.0.
