Thanks for Pics and replies. Im surprised that more aren't doing landscapes with B6, especialy with new features(terrain brushes etc..). I did try TA(but don't remember if it was outdoors). I'll experiment more with TA in outdoor... I know trees and complex objects are hard on any 3D app, but Im not having problems with what Im doing, just wondering what could be used with landscapes for faster HDRI previews, or if HDRI can be used for any type of, mostly, real looking(lighting) outdoor scenes for Bryce.

 HDRI seems over saturated for outdoor scenes to me(maybe because of softer shadows),... and if you use any HDR with alot of color, you can forget using the DTE or presets to preview  materials, you'll have to make your own. If Bryce could only export metaball created objects, then I could use Bryce as a plug-in type tool for my modeling app Shade for some really nice landscapes. GI in Bryce would make things alot easier, maybe version 7.

btw, @Incognitas, nice renders, how long did those renders take?, any postwork?
