I think Bryce's stagnation is why I mainly use it as a modeler...I find the new Terragen which has .obj import functionality, to be the best possible replacement that's going to keep developing for Landscape stuff and a killer render engine. Plus it comes with a Free version that is quite functional, limited in some aspects but 1280x900 renders max is O K and the AA limit of 4 Detail at .6 seem more than adequate for nice detaild.

 

Once in a while I look around,
I see a sound
and try to write it down
Sometimes they come out very soft
Tinkling light sound
The Sun comes up again
