[SOLVED] Why is my cabin interior allowing so much sun in like it has no roof?

In Blender, I've compared the vanilla cabin (outside and inside) of the Peterbilt 389 to mine and I cannot understand why mine seems to be allowing sunlight in. The shadow meshes are the same, as is all interior bits.

You can write almost any way you want, and you might make yourself understood.
But, if you don't use standard English properly, you would also help people understand that you aren't well educated.

Hello. You should have the silhouette of the cabin in shadow material to prevent light from entering. It would only be that buddy I hope my comment helps.

@TruckerWarryor My original post did say that all shadow meshes were identical.

SOLUTION

First, as a test, I made a big shadow box around the cab with all faces facing outward. That did nothing. Then, I flipped the faces inward. Still no difference. Then, I copied over all the shadow meshes (for both interior and the exterior) from the vanilla truck to mine (after deleting mine), but that did not make a difference. Then, I tried the window textures. I figured it was better to play it safe. Still no difference. Then, I decided to copy over all interior meshes, one by one, to my truck, again. That seemed to fix the problem, even though I have no exact idea what must've done the trick. I can only assume it was one or several objects' Material Attributes that were slightly different. I mean, I assumed an actual shadow box covering the entire cab would've done changed the lighting within, but apparently not.

Hello @ChiliBeef . Shadow mesh using this material should have a coarse texture to prevent shadow from coming to the surface. The wider the mesh, the less the saturated shadow will be visible. The mesh itself must have internal and external faces to work well in the model.
