After updating the engine (4.7) All objects surfaces under sun rays become black.
Check if you have Skylight in your scene.
Take a look at this: A new, community-hosted Unreal Engine Wiki - Announcements - Epic Developer Community Forums
i cant find my problem there.
I guess you checked under General Lighting → “Why Are My Shadows Black?” and you already have a Skylight object in your scene and your shadows are still black?
Yes, is have a skylight and no, my shadows are not black.
I create a new map from template and illuminated part of surface are black!
Hmm that’s strange, does it happen also in new project? I remember that i’ve had similar problem with dark shadows HERE. Maybe try checking World Settings → Lightmass → Environment Color (if it’s not too dark) and rebuilding lighting.
