Thank you sir! I dropped that reference kinda hoping that someone like you might make a comment like that. I thought 8 was the magic value but it had been awhile, and the value used was set ages before I knew the threshhold.
As for the backdrop, had I known what it would be used for I might have made it the right shade or gray to match the tunnels, or used the tunnel texture itself on the wall of the backdrop. There's much to be said for the beta room.
Nice little track Charles! Your skills are progressing nicely.
