Based on this, I think it is the DVar setting that is missing and causing the problem. If I understand correctly the DVar setting controls the "Scalar" setting.
There are two settings for that:
"do_scalar" (bool, default is true) and "scalar" (float, default is 1.0).
YafaRay XML parameters
Problem now is figuring out where to put the code... so far I have not been able to get it right...
Hopefully adding this will fix the problem...
