Hi there,
I am currently working on a biome exterior environment in UE5 with baked lighting. I have been using the same workflow for all of the foliage assets- Speedtree > Maya > Unreal. Now I am getting some weird shading / artifacting if you will call it that? In simple terms, the mesh and texture look really bad the further away its distance is.
I will attach a video or photos to explain later, I just want to try to explain thoroughly in hopes someone can help!
Now since I have noticed this I have tried a few different things. Since I have been working in the same workflow, I decided maybe I messed something up upon exporting from SpeedTree, but upon re export to UE, same thing. So then I went to the texture atlas that I sourced and created. Exported fresh BC, and even went as far as recreating the other needed texture maps. But as before, no change.
Next I tried some settings in the material itself- Changed some of the opacity clip threshold, even went as far as disconnecting everything but the BaseColor-Alpha. Still nothing!
Then I tried some final things, enabling lumens- which helped, maybe 90% which is probably what I would have done in the first place, but this project requires me to bake lighting 
And now finally here we are- I have tried resolving it myself before coming here but I am stuck. I will provide as much info as needed if anyone asks.
