hard cut lighting?

[sinful nebula]

how do i fix this hard cut in the lighting?

There's likely a discontinuity in either the mesh normals or its normal map
Check first if it's using a normal map and temporarily remove it to see if the seam disappears

[sinful nebula]

where do I see if it has a normal map?

[gloomy whale]

The material asset assigned to the mesh renderer will either have a field for a normal map or not, and have a map there or not

[sinful nebula]

it doesnt seem to have a normal map

[gloomy whale]

So then it likely is sharp mesh normals in the edge geometry

[sinful nebula]

on the surface of the front of the computer there are 2 faces ( which you can see through the shadows). Idk how to fix that tho

[gloomy whale]

Typically their normals could be set to smooth instead of sharp/flat
But they can also be smoothed/sharpened selectively

[sinful nebula]

that would look weird on my model tho

[gloomy whale]

I'm not suggesting you smooth out the whole mesh, but that you look into what normal smoothing is and then consider smoothing that specific hard edge that bothers you
Or alternatively flatten the adjacent faces so there is no corner there

[sinful nebula]

I think I got it
