Is there any way to make custom renv files easily. The ones in Rhino work quite good but it would be nice to be able to make custom ones of a site. Also is it ok to change the names of the renv files is this a problem? Thanks, Cathal

Hi Cathal - these are xml files as far as I know - the hard part might be writing the bitmap into that, I don’t have any idea hgow that is handled. -Pascal

Easiest is to just create a new basic environment and then load a good hdri image. You can find many on say polyhaven.com - I like their HDRi images a lot as they work well with Raytraced and Rhino Render in Rhino 7.

@studiocathal I would add that you can drag and drop an image file into a Rhino viewport and you’ll get an option to make an environment from it. I’d suggest using HDRI as reflection and skylight enviromnents but a single exposure image as the backdrop environment in the Rendering panel. These will …
