I'm currently converting a model for realtime 3D. The client wants to have the model in gltf with an functioning ao map. But blender exports some of the maps as one. If I have for example a map called metal_roughness.png and a map called AO_stends.png it will export a file called AO_Stends-metal_roughness.png which does not contain any ao informations and thus renderuing the object black. I'm using the node setup from the Damaged helmet testfile. Can anybody explain this behaviour? On some parts of the scene it works on some not.
