Cloud over the mountain range v1

Thanks, Alexandr. Version 2 with HDRI can be found here: http://artzone.daz3d.com/azfiles/gallery/dh/tm/rquzv51fqjvzglt4u2w2pk5m56adz6-full.jpg

Interesting picture. It is like pastoral painting - I like it:) And yes - volumetric and HDRI is very slow combination to render.

Ah - volumetrics and HDRI, a render horror. Bryce 7.1 lets you exclude objects (the volume clouds in this case) which speeds up the render enormously.

Thank you for your comment Horo. In fact, I uploaded the second version of this image. But the moderator is not missed. Here is a description of the second version. Created in Bryce 6.1, Render in Bryce 7 Pro. Render Normal AA, Bryce HDRI (Default Mode). Render time is 2:18:45:00 (64 hour, 45 min) The scene contains: 119 Bryce Trees, 1 Terrains,1 Slab, 1 Plane. In normal mode, this scene is rendered with a half-hour. With the use of HDRI, the quality of course better, but at what cost? Of this work I was inspired by examples of Horo, David Brinnen, c-ram.

You experimented with a volume cloud here. The result looks quite good. The green has a bit much of blue in it for my taste.
