Any tips on how to achieve smooth lighting / shading on polygons in directx based real time rendering engines? It seams the the more "extreme" or varying a surface is in angles and elevation, the more pronounced the shading on individual edges and polygons become. I am developing in Maya. Attached are images of the polygonal surfaces in Maya, and in our game engine. I cannot find a way to reduce and/or eliminate the severe spiking in the shading.

either there are no images attached, or I can't see them. can you please revew your post :)
