The map I am working on has a lot of lighting issues. I tried fixing a lot of them with methods suggested in the Discord or just ideas I had on my own, and yet it always ends up the same, or sometimes worse. I figured the forums would be a good place to ask, so pardon if some of these are noob-tier questions. A heads-up: I am compiling using these settings: I seek help in fixing these issues; Any ideas on fixing them would be greatly appreciated, any other info I will provide on request. I really just wanna get rid of these issues so I can stop having to think of them in the back of my mind! A lot of these will be commentless, but I will number them. For anyone that's gonna help; thank you! Here we go. 1. Strange shadow behavior - the upper platform with the two support beams is a func_detail. 2. Strange shadow behavior again. 3. Again. 4. Vent looks very out of place. 5. Once again strange lighting. 6. 7. This one actually has quite a story behind it. Initially, I used the normally-in-tf2-available industrial pipes! With those, the entire set of pipes inside the support tower would be black. As recommended by the Discord, I decided to use Fubar's pipe set instead. (https://tf2maps.net/downloads/fubars-quality-plumbing-set.2783/) This only fixed the issue partly. As you can see, some of the pipes are oddly enough still entirely dark! A different perspective. Only some are properly lit, despite all of them having the same settings. But looking at the back quickly shows that even those which have some lighting going from them, seem to work properly. 8. Shadow doesnt seem to transition well at all. 9. 10. 11. 12. 13. 15. 16. The "beams" or "wall details" are all func_detail. 17. func_door that has lighting leaking through it. 18. 19. 20. 21. 22. 23. I know this is a whooole lot but I simply can't get these fixed, increasing, decreasing, vertex off, vertex on, smoothing groups yes or no, the results are just not good. Thank you in advance!
