I have a 3D armor which was textured in Substance and exported following that pipeline: https://www.khronos.org/blog/art-pipeline-for-gltf, that is to say with a ORM map.
However, once the maps pluggued in the right nodes in Blender (I'm using the glTF metallic roughness node from https://github.com/KhronosGroup/glTF-Blender-Exporter)...the metal renders like plastic, not at all like in Substance. I have tried to toggle Color / Non-Color Data modes, to darken the roughness... Nothing works.
Can someone please explain me why I can't seem to get the metal effect right using the GLTF pipeline? :(
Thank you very much :)
