Cruciform Vegetation

Spur

Hi everyone! I'm wondering if anyone can give any ideas on what can be done with a shader to eliminate the light/dark shading effect associated with simple cruciform vegetation in XNA. Sorry if this is a big vague as I know absolutely nothing about shaders and just looking for some general thoughts.

Generally you'd bend the normals of the mesh itself a bit, so they point outwards from the centre of the bush.

Thanks for the reply. That had crossed my mind but I wasn't exactly sure how that would work out when it is just two intersecting planes. Would it be best to add more geo and adjust the new normals in the center?

vertex normals, tweak the vertex normals.
