Hey Everyone
Need some help with the shadows, on the yellow band on the bottom half, there is a shadow gradient, but its giving me these harsh lines. Any idea what is causing this and how to fix it?
Thanks in Advance

Yeah it’s currently at 2048, so i dont think it is that.
Have you tried to use different Lightmass Settings ? Can you test it with the following settings ? Or play around with the Indirect Lightning Smoothness and Quality.
Hi!
Could you show us the uv map of this mesh?
…also the material if there’s any emissive or metallic or low roughness…
You know what your settings actually mean?
You go into detailed calculation then a random 100 lightbounce + only 1 from the skylight + an extreme high quality setting and then at the end you blur the hell out of your calculated result!! :S
Sure. If you try to eliminate a Problem you need to start from somewhere. The smoothness is a bit high but it’s more like a starting point. And since the Static Level Scale is smaller you need to increase the Quality. I always set my light bounces high since it doesn’t add much to the baking time. So do you have another approach to something like that ? The scene itself has only one object and a bit trial and error could help 
So i tried these settings and got a better result but still not great cause it now has vertical lines.
Not sure if its good or bad but it is progress.
Is that your lightmap uv ? It looks like the yellow top part is overlapping but it’s a bit hard to see. Do you get any error messages if you are baking the lights ?
Hi!
I don’t see the whole mesh so I’m just guessing what is what on the lightmap…
BUT! It’s way far from ideal even with extreme high resolution!
There are islands that way too close to each other and then you have like half of the whole uv space empty…
Also you have really small parts and not even straightened up but in a curve: again not ideal, you need to be lucky to get a clean result!
What I would do is straighten up that small part too (maybe that’s the yellow part?). Scale everything up as much as you can (can be non uniform), don’t leave small parts!
Also I would use a simple gray material till you test the lighting and when it’s ok only THEN turn on all the fancy stuff like ao, normal, metallic…)
You should get away with a lower resolution lightmap if your uv’s are fine!
