Why have i this behavior?
Hello, i am a newbie . I put an object called “Curved Stair” in the scene then i transform into a “StaticMesh” and become black, i don’t know why. I am working with huge elements.
Please show us your material and scene lighting setup 
it’s the same material for the stage and as the stairs.

lights
i putted into the scene a textrenderactor and i wrote something. When i changed a font the text disappeared! i dont understand.
can anybody help me for the lights?? because i have several problems and i don’t understand. I think i dont know how i can push in this program. I use a huge and fine models, i dont know if it’s enough or better support this program. I saw very marvelous projects. Anyone there!?!
These are very strange warnings that I have never seen before. There aren’t any similiar topics in anywhere aswell from what I searched.
I suggest making this post in bug section of Answerhub, an Unreal staff might shed light on this better than anyone.
thank you so much. I hope to solve it.
