I’m trying to make something like
No idea how to get the light to shine from above and cast nice shadows across my geometry though!

Here’s where I’ve got to so far. Any pointers appreciated!
May not be exactly what you’re looking for but there is an old and super handy component by @jeffers and updated by @matthewwachter at this topic thread:

This is pretty tried and true but does have its limitations since it is a 2d effect. I have done some work towards locating the light source in 2D to keep the center matched to your light source in camera space that I can dig up and share shortly.
But per your image it seems like you maybe or more just looking for a light with shadows and bounced light? In that case you will need to “fake” some global illumination most likely in combination with a shadow casting light and maybe the volume lighting effect to add a little flare… unfortunately Global Illumination is not available out of the box in TD and is pretty tough to do right now if things are in motion ( for a statically lit scene you could bake things in another app and apply textures which would still give you the ability to move the camera around but not the sun).
Another pointer per your file, for an environment light you will want to provide an equirectangular mapped image and preferably at a higher than 8bit depth, so it would be an exr file.
If I have time I can dig some things up to share, as there are some techniques for achieving these sorts of looks despite some of the lighting limitations in TD right now.
Thanks for that! Having a look now. I’ve heard rumors that Derivative are working on something to help with global illumination… hopefully that’s true, so much beautiful work is done with it.
Would love to see anything else you can dig up technique-wise here!
This is a well made course by TD light Master Lucas Morgan, who explains a technique to achieve real 3d volumetric lighting with raymarching:
