Intense shadow artefacts on mesh

Hey! I’ve been making cars within blender recently and seem to be having issues with how ROBLOX’s lighting impacts the appearance of the meshes surfaces.

The issue I seem to be having is towards the front headlight, taking a heavier impact from shadows than the rest of the surfaces, but it seems perfectly fine in blender.

Inside of Studio : (Turned the part impacted to blue to show a higher contrast within the shadow Issue)

I’ve tried multiple solutions such as retopologising my mesh, triangulating the mesh before exporting (basically getting rid of N-Gons), Increasing poly count to limit distortion within the faces etc. I couldn’t find anything on forums due to not knowing how to word the issue I was having.

Any help is appreciated! --Lost :).
