FMX: The brightness thresholds are too high in FMX when the sun is low in the sky

The brightness thresholds for the FMX are too high when the sun is low in the sky

Problem

When the sun is low in the sky, FMX reduces the thresholds by up to 80%. Starting with SW V 1.21, the threshold reduction can be adjusted in the diffuse light management under the Emax parameter.

Workaround

Alternatively, the thresholds can be switched between two shading programs using an EP or ZP.
