Hello,
Thanks for your question! I see my your screenshots that you're using the Corona render engine. Since this renderer isn't an Autodesk product, and the issue may be tied directly to this render engine and how your Corona-specific maps are set up, could you post your question to the Corona technical support folks to see if they can offer some insight here?
Please let us know if this helps!
