Hi. I am trying to render a cinematic of a landscape but the Global DistanceField is actively affecting my skylight. If you look closely there is a hard cut in the trees where they “pop”. I dont want this! For we to see it clearly I scaled the Intensity. ![image](https://d3kjluh73b9h9o.cloudfront.net/original/4X/8/a/f/8af75fbbeb669f8608833e070868aa6227547d0b.jpeg) And here is the visualization of the Global DistanceField. ![image](https://d3kjluh73b9h9o.cloudfront.net/original/4X/4/6/a/46a58999fdc4d3af3ff8c5517d9e9fcd9985cfc3.jpeg) And here the DistanceFIeld AmbientOcclusion. ![image](https://d3kjluh73b9h9o.cloudfront.net/original/4X/3/d/d/3ddb49984864abcb159611f3a976d365cc9b7620.jpeg) I tryed to change the r.AOMaxViewDistance as sugested [here](https://www.reddit.com/r/unrealengine/comments/zdodnv/i_using_ultra_dynamic_sky_in_this_scene_but_even/), but that did not worked. What to do? ---

In the Ultra Dynamic Sky the DFAO options in the Skylight section does nothing! ![image](https://d3kjluh73b9h9o.cloudfront.net/original/4X/6/6/c/66c14e4b64b5f93d066b413d7184f9095392b25f.jpeg) ---

Hi, Have you try to crank up the Distance Field resolution in your tree static mesh editor ? ![image](https://d3kjluh73b9h9o.cloudfront.net/original/4X/b/f/e/bfefb667ca88bcf70e4d87dcacc329f995793819.png) also, have you try to crank up the Distance Field Shadow distance in your Light ? ![image](https://d3kjluh73b9h9o.cloudfront.net/original/4X/3/d/b/3db5ac80b29b9195ee1f97cfecfbac6f549e5881.png) ---

Hi! 1. Yes I did, but they are Nanite foliage so i dont think that would work. 2. Yes, the UDS has a higher value by default, but just for checking I cracked everyting up and got no changes in the scene.

I see, Just in case this might help you: [https://docs.unrealengine.com/5.0/en-US/distance-field-soft-shadows-in-unreal-engine/](https://docs.unrealengine.com/5.0/en-US/distance-field-soft-shadows-in-unreal-engine/) Also, have you tried to crank up the Lumen scene view distance in your post process ? ---
