This is an attempt to get some broader feedback and hopefully solve a lighting issue I've been having with recent Nightly builds. I've had frequent assistance from m!m in trying to resolve this, but we appear to be at a loss now.
Builds newer than October 31st have no ambient lighting for me. The glowmaps work, but all ambient lighting is gone. I've tried increasing the ambient factor in the launcher but there was no change. Oddly enough, Debug builds don't have this problem for me. m!m was unable to reproduce this, but he isn't using an ATI card like I am, and I was hoping that other ATI users might be able to confirm my findings. I've also found that jumpnodes render as black under these builds.
You see an example of my lighting issue in the Dec. 6th Nightly Build Thread
My card is an ATI HD 5770 with 1GB RAM. I'm using Windows 7 Pro 64-bit. Because of this, I can't used the very latest drivers. In fact, the last driver set released for my configuration was in 2015.
Has anyone had this problem, or can shed some... light, on what might be causing this?
