Why foliage loosing contrast?

hello there

In this Picture: file4.de - Easy file transfer
you can see the foliage getting less contrast at a certain distance. it ruins the look.

Does anyone know how to get rid of it?

! i checked “PostProcessVolume” when i turned it off it had no effect. Also theres no fog enabled.

i guess it is the foliage itself?

Thats your LOD / probably a bill board or an impostor.

an impostor will always be different from the rendered item, since the light will hit the real tree a certain way, while the billboards usually have no light/shadow at all.

If your light is static you can update the material with a better render to get a closer look.

If you are dealing with a dynamic environment you are sort of stuck to the best you can get.
that, or don’t use impostors if your target platform can afford the cost.
