Hey Jonathan. You are right, the bottom faces look a bit off, I hadn’t noticed before. Seems like I need to do some more quality assurance on the models I make… I’m not sure what causes it. It doesn’t really appear in blender itself. Thanks for wanting to look into it.
I’ve shared a google folder with two blend files: https://drive.google.com/drive/folders/1y9Id2C19S4yqS26BYAGR5TPB-1DVvZOx?usp=sharing
file: “finished_2”: this blender file contains only the low-poly model with the normal map and is the file that I uploaded to sketchfab.
file: “finished_1”: this blender file contains all the models. It has the original high-poly model, and the self-created low-poly that I use, as well as the cage object in there (and of course the normal map).
I just checked the low-poly model in finished_1 again and it does not seem to exhibit any odd shading behaviours.
Cheers,
Tom
