I want to create 2 images with mirrored lighting. The direction of the shadows is not particularly important. It is only important that the second image casts a shadow that goes exactly into the opposite direction. I use an HDRI without additional light sources for the lighting. The light source appears to be in the upper right corner as the shadow points to the lower left.
Whatever I try to change the direction of the shadows changes the color significantly. Is it possible to mirror the HDRI horizontally without affecting the color?
