Description Adam Goodenough 2014-06-18 11:06:29 EDT
Observation of direct sources through non-unit transmission atmospheres is equivalent to no-extinction.

Recreate: add a real atmosphere to the Sources1 demo
Comment 1 Adam Goodenough 2014-06-18 11:08:34 EDT
There was an issue here with the method used to prevent infinite recursion on the direct source calculations that set the ray bounce generation to a value that resulted in the atm code to skip the path calculation. A more robust method has been added in 4.6 and transmission of direct sources should be as expected.
