I am building a scene where a “house” building mesh can be viewed from different angles. I want each wall to be illuminated with their own DirectionalLight. For whatever reason, however, the right wall is not illuminated. I know it has something to do with conflicts between the left and right light sources, as when I disable the left light source the problem disappears.
I replicated my project here, the positions of the camera, building and light source are the same.
