Devlog: Unity Lighting bug
Some days ago I updated my version of Unity to 5.5.0f3 (64-bit). After the update, it broke the lighting of some test scenes I made, with weird stains and reddish colors being reflected by some objects and shadows.
Whenever the scene built its lighting data (by Auto-Build, or by clicking the Build button below) , its main reflection probe became glitched for some reason, maybe because my notebook’s (Intel, integrated) graphics card is a bit old. In my PC (that has a newer chipset), this bug doesn’t happen. http://i.imgur.com/l3z2bTP.jpg
After some tests with other lighting settings, I noticed this version of Unity seems to have added a new option inside the Environment Lighting configs: the Reflection Source‘s compression level. The option’s default value was “Auto”, in my case this was giving the same effect as the “Compressed“ value, which generated the glitched reflection probe: http://i.imgur.com/HWoOkAA.jpg
Finally, I changed the setting to “Uncompressed”, and then the light probe was generated correctly, fixing the lighting in my scene. http://i.imgur.com/lpH2tsh.jpg
If someone else bumps with this bug, I hope this info helps you to fix it! Cheers! ^-^
