Yeah this is really sloppy. There’s an edit in the video to say the texture is in the exercise files but it doesn’t say what the texture is or where to find it. You expect it in the lessons files and it’s not there. But honestly why even edit this part out?
I’m curious how you know the texture is VeinsTexture_512x512 cos I can’t see that from the video… it’s also frustrating that the node shaders are worked on in a tiny window in about 25% of the screen. The tutor knows what she’s doing but everyone else is trying to follow along!
