Yep, the model-combined effect is the only exception to keep backwards
compatibility with effects that inherit from it. The <generate> tag is
placed on the child effect, not on model-combined.eff, so it's

If you are using OSG 3.6 it's a known bug. You can remove the
<clustered-shading> block in $FG_ROOT/Compositor/als to prevent the
crash.
