Lighting Needs to be rebuild - each time I move SpeedTree

[iniside]

I'm using DominantDirectionaLightMovable, because I need fully dynamic lighting and do not bother with lighting building.

1) Add speedtree > play in editor > Works fine
2) Now move SpeedTree > Play In Editor > Lighting Need to Be rebuild.

Do you have any static lights in your level, like point lights or spotlights?

[iniside]

No. Only single dominant light.

Dominant lights still use lightmaps for static objects.

Dominant lights still use lightmaps for static objects.

That would be the case but:
a) this moveable light
b) this happens ONLY with SpeedTrees. I tested it with static meshes and it working as intended. I can move them, remove, rorate and so on and lighting do not need rebuilding.

Unchecking "Use Precomputed Shadows" under SpeedTree Properties > Lighting worked for me.
