First HDR Experiment
« on: August 14, 2018, 11:34:57 PM »
LANDSCAPE: Terragen 4. PROCESSING: Aurora HDR. NOTES: I'd like to learn how to render and process the sky separate from the landscape. This image might also be improved with clumps of grass. Right now, the green and brown are just built-in shaders. Please excuse cross-posting.

If you want to create HDRIs, then I believe it is beneficial (if not straightforwardly recommended) to render both sky and land in one go. HDRIs source lighting information from sky, land, surfaces and bounced light, so separating these items may have detrimental effect on the image's accuracy.

Get a Render Layers node and Plug that into the centre input of your render node. On the Render Elements tab, select surface RGB, Atmosphere RGB and Cloud RGB. Those three added together will give you the beauty. For them to render out, you need Extra Output Images ticked and a path defined in the Sequence/Output tab of the render node.

Render Elements should properly account for the info in the other elements, e.g. a separate cloud element will still be receiving lighting from the ground and atmosphere, it's just separated in the output.
