Light and Shadow Problem

I have created a level in UE4 using timeline to move the directional light around the level from night to day using both dynamic and stationary light in my scene. Now the shadows and light of my foliage (painted on foliage) is really bad, the grass is really light green as if it isn’t affected by shadows and the bottom of my trees and some flowers are pitch black Does anyone know what I can do?

Also when i up the light map resolution of my trees it says the instancefoliage thing (my painted on foliage) is too large.

You likely need to adjust the normals of your grass/plants so that they point in the right direction so as not to be lit incorrectly. It’s a weird issue, but makes sense when you understand the problem.

Hi Animism,

Lightmap resolution is not a concern if you’re using a dynamic day/night system. Since your light is set to movable there is not pre-computed (baked) shadows necessary. The warning is there because the lightmap resolution is higher than necessary for the cluster size of the painted foliage. It’s just a warning and since you mention you have a stationary light (hybrid dynamic and static) in your scene you’re seeing this. Typically, stationary lights would not be used with any exterior lighting for a day/night system since baked shadows would not go well, in some situations, with light that is changing position. To remove this warning, make your lights movable or lower the lightmap resolution via the foliage tool.

Tuxedost may be right about your foliage, but with an image to see it possible it could be something else as well.

Please post a screen shot and we can better give you tips for where to start.

Thank you!
