robdyck Posted September 25, 2019 Share Posted September 25, 2019 A bit late in the day to be starting an old topic. What the heck is the deal with random wall lighting issues in PBR? I've tried every toggle and adjustment I can find but I can't get a couple of walls to display properly. It's clearly not a specific lighting issue because the problem is with a few walls. I recorded the PBR adjusting itself and somewhere along the way it gets it just right...but then just keeps on going. All I'd need is a slider tool so I could manually reverse / forward that process and then stop it where I'd like it. And while I was working on this I had an epiphany! I added a wallcovering to my offending walls, using the same material, and BOOM! They all play along now! This could possibly go in the 'tip and tricks' section. 2 Link to comment Share on other sites More sharing options...
Chopsaw Posted September 25, 2019 Share Posted September 25, 2019 Nice work Rob, Not really sure if that is a known issue or not but it might be a good example plan to send in so that does not happen in X12. Link to comment Share on other sites More sharing options...

This problem affect more than just walls. In the screenshot below, the newel posts, the clipped bottom of the timber truss, and the gable wall are all affected. The same shot after opening and closing the 'adjust sunlight' dbx. Link to comment Share on other sites More sharing options...

It's all in the way you build, cutting corners on the railing end up causing an issue, elements need to be contained to one source of illumination. There are some funky things going on with that scene that I could probably help with, though I know its a pain to share your particular plans Link to comment Share on other sites More sharing options...
Renerabbitt Posted September 25, 2019 Share Posted September 25, 2019 thats not dismissing the issue or putting you down, PBR just illustrates the corners we cut for sake of production and hoping the tool will work in the end..unfortunately PBR has some core flaws that are difficult to fix Link to comment Share on other sites More sharing options...
Renerabbitt Posted September 25, 2019 Share Posted September 25, 2019 If you cranked roughness of the material all the way up and set it to a matte material the issue may go away, but you have no gloss then Link to comment Share on other sites More sharing options...
