Since this is a current Mac problem that I had asked Kent about, he asked me to post this to the Class Homepage:
I am using an iMac and almost always use Environment Lighting with HDRI images for the background lighting – these are always mapped using a Texture Coordinate node and a Mapping node so that I can rotate the environment to change the lighting/mood of the final rendered image.
I have found that in trying to use Eevee I can no longer use Environment Lighting with HDRI images with the mapping feature. When the environment image is used “as-is” (without a mapping node) then it works fine, but once the Texture Coordinates node and Mapping Node are used the whole scene goes pink.
If there are any Mac users who have experienced this or know a workaround that you could post, that would be great – thank you 🙂
