Sorry to hear about your PC man. As the poster above suggested, open up a donation page I am sure that the people who benefited from your videos here will happily chime in a few bucks to get you up and running again. Considering that you’ve made over a dozen hours of professional-grade lighting education warrants at least that much.
I do have a quick question though:
In the last video of the first session the grass seems to not really take the landscape light info, as seen below. Is this due to the texture base color mismatch or is there something else that needs to be done to blend this?
