Ray traced shadows problem: CAUSE, HOLES IN DATA

[Tangled-Universe]

Looking at the example-pictures dombib provided I still find it awkward that the "holes" are being rendered somewhat correct with raytracing enabled. Without raytracing it gives strange shadows.
It seems that raytracing influences the way TG interprets elevation-data, but that doesn't sound logical??

Both are rendering problematic terrain data, the errors are just more conspicuous with shadow rendering on. The shadow rendering functions in such a way that the data provided by the erroneous terrain values creates particularly notable issues vs. without shadows.
