It´s strange, look at how the lighting is…I have made another model and it rendered with a normal lighting. What could be happening here? It´s soo quad O_o
Personnaly i don’t know. check the smooth option and may be if you got embiant occlusion turni it off.
And post your scene if you dont find
it looks like it is set to ‘solid’ ( the default ) instead of ‘smooth’, also, toon shading appears to be enabled, i assume that is intentional?
