In the “Carrara is messing with me” category comes this oddball: Same scene, all I did was drag the blonde image texture up out of the bump channel into the color channel and the blonde render takes significantly LONGER to render…. Despite the fact there are now fewer image maps in the scene… HUH?
Brunette pic takes 36sec to render (blonde map is in the bump channel, brunette map in the color channel)
Blonde pic takes 58sec to render (blonde map in the color channel, NOTHING in the bump channel)
Carrara I love you, but… this makes no sense at all.
