Hello! We are currently experiencing an issue with back-facing mesh normals being too dark, regardless of the lighting conditions. The same issue occurs in all the two-sided shaders I could get my hands on (Alloy, UBER, free two-sided shader package, etc.). We've also tried different ways of adjusting mesh normals (by projecting them from the dome, perpendicular to the ground, etc.), but seems like it doesn't make much difference. Perhaps this is a Unity issue, and nothing to do with the shaders themselves? We are currently on Unity 5.6.1 but the same issue is present on 2017.2 as well. Here's how the mesh in question looks like with UBER two sided shaders (although the same issue occurs with other two-sided shaders): And here's how mesh normals look in 3ds Max: And here's how the same mesh looks like when imported into Unity, without textures. Notice how dark the back facing normals are: I really hope somebody could provide some assistance. I thank you all in advance!
