Inclusive saving all texture maps in linear, untagged (RGB 8bpc) or in sRGB. Needless to say we tried (what feels like “everything”), many things - to no avail.
The model used is a GLB, and the maps have also been tested in various ways, coming along with the GLB export, or simply plugged into the material within the sandbox or playground. The below linked screenshot is an assembly of screenshots showcasing the visual differences between the materials created in Blender, Substance Painter, Photosop, and even if just applied with a simple hexcode in the basecolor of the PBR material inside Babylon JS.
We have been battling with this for the better of 3 weeks now, and hope to find someone that might have an answer.
