Following Lino Grandi's tutorial about using AOVs + Z-Depth for fog in Octane for Blender and trying to apply the same concept in the C4D Octane isn't quite as straightforward as I'd hoped
looking at the AOV section of the manual, the example it gives shows the use of an OSL Fog Opacity node to create a fast fog composite, where can I find the OSL script for this?
is this demo scene available for download somewhere?
