Hi there, I saw a YouTube video featuring Laigter https://www.youtube.com/watch?v=WZ-YnnZTzUw&t=186s where a normal map was created from a standard image an file and was thinking maybe I could do the same with a photo of a living room scene that I wanted to add a lighting effect to. I downloaded and ran v 1.3 on my Windows 10 laptop but I am unable open any image files. Any suggestions?
