I've been going through all kinds of lighting tests for the last hour. In short, this one enhancement is going to be VERY powerful. HOWEVER, that said, it is undoubtedly going to cause some major headaches for repainters and devs alike. First of all. The ONLY way for your repaints to look as they should (the way YOU, the repainter intended them, and advertized them) is to publish your HDR Slider numbers, and Dynamic Reflection Values. Otherwise it will be a royal mess. Especially for reflective bare metal paints. I've honed mine in to correspond to how my B-58's should look. And I'm happy with the results. Most everything else has followed suit. Without knowing this, it will be difficult if not impossible to allow each user the correct experience which we are trying to share. As such, the readme's of all repaints should as a best practice start to include your settings, or at least basic settings. When repainting it might be helpful to publish a best practice settings for HDR and DR (dynamic reflection) indexes for the repainter to set when testing out new paints. Otherwise the color saturation will be based on non standard lighting/saturation/bloom settings... Just a thought. But honestly, we've entered a whole new world of possibilities with 3.1 here. Although most are treating it like it's v2.6, it's NOT. Under the hood it's a generation gap ahead of where 2.5 was. Just in terms of memory handling, object handling and performance. I'm getting FPS numbers I've never seen in P3D previously. It is superior in everyway. that's with REX installed and DR set to ULTRA.
