Lighting problem
I'm having a problem lighting this plant. Below is how it looks in model design mode

And then when I go to render preview it shows some of the leaves as black

Even when I rotate the light 180 degrees the black stays the same.

The leaves are all the same material. I put an all green decal on one leaf and it was also applied to all the other leaves. Even when I get rid of the sunlight and just use environmental light the black still shows up in the render even though I can see the green leaf texture fine in design mode. Any help would be appreciated thanks.
