Hey leleuxart,
The sky materials are dds texture files (2048x2048) that are imported via a program called Spacescape, by Alex Peterson.
Initially, prior to changing the material, all is cool, on the first change the star effects are lost. The star itself has a PPV, and I’ve set the Unbound to on. Still no change. When you relate to the post-process settings, where actually are they? in Project settings? I can’t find anything to do with Min/Max exposure, just ‘Auto Exposure’ under Project Settings\Rendering\Default Settings.
Based upon the attached screenshots, is there anything that looks obvious to you? I think your stated theory sounds cool, however, I don’t know how to block everything out initially.
Thank you for your help =]
