I would just like to mention that DEM Earth for R21 has excellent support for Corona, and although I have only used the demo version to test compatibility with, Corona is by far, my preferred and absolute favorite render engine. it simply works. I can not say the same for for the other engines I have been trying.
In DEM Earth 4.013, I introduced 3 new shaders.
Simple Slope.
Contours.
Valley fog.
They all work perfectly with Corona without any fuss, pretty much in realtime, with no need to bake anything.
A big thumbs up to the the Corona team for doing better native shader support than the host app!.
The only thing I miss is some kind of multi instance or scattering support.
