Normals on bottom half of tree crown are inverted #3

Trees aren't lit up properly. Sun (light) is positioned in the upper right of the screenshot below, but the bottom half of the tree crown is lit up on the left side.

I think the issue stems from the fact that the shape i used for the bottom of the tree has negative height. I predict this can be easily fixed when objects can be initialized as rotated, and I will initialize a rotated pyramid rather than a negative-height pyramid
