So typically this is without tomatoshade is the picture without tomatoshade but some bump and spec maps and it can on;y provide a decent amount of light off the aircraft. But the other ones; you can notice the light properly reflecting off of the aircraft. Albeit, those aren't the latest model. I just have them to show you the power of tomato. But the reason ?I ask for PBR is because Tomatoshade is not supported but 90% of devs out there. And PBR is more customizable to certain parts of the aircraft. https://imgur.com/a/ChaaiBV
