What's the correlation between the number of polygons in an emitter and render time. For example, if you have a cube emitter with 6 sides, vs. a sphere with 100 sides.

It's a simple test to do, Brodie. Please report your findings when you are done.

I recently had a high poly emitter in a scene; It didn't seem to cause any extra noise.

fair enough...

All tests were done with the camera in the same location using primatives from Studio of approx. the same size and with the same material applied. The emitter was the only object in the scene.

Plane: SL:12 # of Triangles: 2 Time Passed: 23s Benchmark: 3228.69

Cube: SL:12 # of Triangles: 12 Time Passed: 31s Benchmark: 2511.20

Sphere: SL:12 # of Triangles: 5040 Time Passed: 52s Benchmark: 1451.43

Based on this little test I'd say that it seems # of polygons does affect your render time however the difference becomes less and less as you increase the polygon count.

interesting!

could you repeat the test with these 3 setups enclosed in a "room"? maybe with reflections the
difference will be bigger.
