A Simple Example - the Cornel Box

We'll demonstrate the effect of those two parameter on a simple Cornell box-like scene.

You can download the starting scene here (for 3ds Max 2010). It includes a very simple setup of a closed space with differently colored walls and a spot light. The walls have V-Ray materials applied to them since currently photon mapping works only with V-Ray materials.

Note that the spot light has inverse square falloff and quite a high multiplier. This is because real-world lights have inverse square falloff, and photon mapping produces inverse square falloff by default.

This is what you get if you render the file straight away.

We'll demonstrate the Effect parameter Two of those on a Cornell box-like Scene Simple.

You Can Starting the Scene download here (for 3DS Max 2010th). It includes a very simple setup of a closed space with differently colored walls and a spot light. V-Ray Applied Materials have the Walls to them since Photon Mapping currently works only with V-Ray Materials.

Note that the spot has Inverse square Light Falloff and quite a High MULTIPLIER. This is because Real-World Lights have Inverse square Falloff, and Falloff Photon Mapping produces Inverse square by default.
