Hey you're back!
Unfortunately it no longer exists, at least for me. The files were in the shared folder we all used for the production and after production wraps up, Kent always cleans that out and I never made a back up of that, because why would I, it's so many GB's of data from everyone involved. I think Kent does make a backup, but if I remember correctly, he said he only kept the day house files? But anyways, weren't you making the night version on your own? Learning all the Blender so you would make your own more awesome night version?
I have a night file ? But it's different than it's in video ?
Can I give you ?
Can I give you ? You can Check it the problem of night scence.
Apologies, but that was a big project that took a lot of time, I cannot. I thought you were doing it for the challenge and for the learning. So in this case, perhaps one idea is to hire someone, you can tell him what you want and he'll deliver the results. I wish you the best in accomplishing your task.
I have a .blend you need to give few hours to render look a like ?
