I am leaning to a 4 level quality choice :
0 - actual state : clouds are making holes in mountains when seen from below, translucent surfaces are making hole in clouds underneath.
1 - clouds are blended with mountains
2 - translucent aircraft surfaces are blended with clouds but with problem with underlying 3d static objects ( clouds between the propeller disc and 3d objects are not seen )
3 - total correctness
Perhaps 2 and 3 can be collapsed with no extra cost. There is already a
property to enable or disable the extra work. I will add quality on
rendering soon.
Fred,
At one point, clouds were drawn "back to front" with respect to altitude. This should avoid transparancy issues, except for things like trees, prop disks, and canopies that may get drawn earlier. Perhaps subsequent work on clouds caused this drawing order to be lost, but if we draw the clouds back to front based on altitude, it should reduce most or all of the issues you are working on without needing any sort of extra multi-pass effort.
Regards,
Curt.
