Hi. I am finishing a project I started a long time ago, probably 2.79/2.8.
I have this strange behavior where two meshes with the same material applied (no other materials on the slot menu) look completely different.
You can see there is a patch way darker than the rest.
I checked the normals:
Also, look different.
I am using the Sanctus library, but I doubt it is related to the shader.
Even when I take out the materials I can see something is off with the darker mesh:
I can notice some triangles on the darker white patch
Do you know what could it be?
Thank you
