Hi there,
I have a question, I hope it is the right place, I am starting to work with PBR and for this I have started working with the Damaged Helmet model ( glTF-Sample-Models/2.0/DamagedHelmet at master · KhronosGroup/glTF-Sample-Models · GitHub ).
And my question is, in all the tutorial i have been able to read they speak of metal and roughness as separate textures maps.
In this case I only have a unique texture for metal and roughness.
Is there any way for this texture to extract the roughness map and the metal map?
