Shading issue

Hi! I’m new to blender. I have downloaded a free model of a spaceship and edited it a bit. I used discombombulate to add some plates and added some texture. Now I’m having some troubles with shading. They look bad in eevee, a bit better in cycles, but even the simples animation looks bad, oth in eevee and cycles. Do you have any idea on how to solve this problem? Thank You

What shading? You don’t appear to have any materials applied so there is no shading.

Add materials to your objects.

i guess what you mean is the edge bleeding in the cornes? i think this isnt a shading issue, maybe this will help you:
