Interior Scene With Mr Sun And Sky Problem

[p-4204-1]

I am creating a interior scene using max 2009 w/mr sun and sky.

I get the error message "no photons stored after emitting 10000 pnotons from mr/sun01.

I know this is usually because the photons don't have anything to bounce off of so I created a sphere to enclose my scene and flipped the normals so they are facing inward.

I also applied a standard white material to the inside of the sphere.

Lastly, I put a check in the mr Sun Photons box "use photon target" and set the scene to 600 feet.

I have created new sun and sky systems, rebooted my computer and elliminated all other light sources trying to solve this.

Yesterday it was working greate. What could I have changed that would cause this?

Dont know about max but in maya the photons would bounce of the surface in any case since they dont care about normals for most photonic shaders. So it doesn't really help.

Its not a error per see tough. Its more of a warning as it may indicate some nonptimal performance gains.
