Currently trying to export an emission texture along with the obj & mtl. All other texture work fine, albedo, roughness, metallic, normal, but not the emission.
Unfortunately if the "Add Shader" or "Mix Shader" nodes are used, none of the textures above are added to the mtl. If the emission texture is simply added to the emission slot on the principled BSDF the emission texture works within blender but is not included in the mtl when exported.
Both ways have been attempted and both are unsuccessful. Any help in getting this bug fixed would be great.
