Global Illumination crap

Global Illumination, final gathering making crap

I'm working a scene in Soft 3.9.1, and trying to set global illumination. There is, for now, one light.

When I started setting up GloIllum parameters, everything was fine when previewing. But when it comes to apply the final gathering (in the Light > Photon Director > Render Setup), the preview shows squares of different tones.

I tried to increase/decrease the following parameters, with no success: the photon number, the accuracy (render setup) and the min/max radius (also in render setup).

I'm I missing something? Please help me.

To get rid of the squares use final gatherings Min and Max Radius setting. Set it really low (like Max=.1 and Min=.01) The lower the better. But watch out... set it too low and it will take forever to render.

Also, I wrote a tutorial on GI and FG in Soft3D that might help you: Tutorial #52: SOFTIMAGE|3D and mental ray
