Volumetric data with filmstrips?

Would be happy to share some source files if you think this sort of approach would be a useful addition!

This uses volumetric OR surface shaders to produce a dense volume. Obvious bottleneck here is the size of the texture... but I was able to get pretty hefty sizes in before I started noticing problems!

Oh boy, this totally flew under my radar... Sorry for the very late response.

I implemented volumes as a simple combination of 6 axis-aligned slices which is very memory efficient but using an actual volume has obviously its perks. I will have a look, thanks!

By-the-by: not sure if you kept up with this but Blender now supports OpenVDB for volumetric objects. I had a play with it but at least back then I struggled to find out the right settings to render it like in your screenshot. Have you given this a shot?

no worries!! haven't played with OpenVDB recently, I had a similar experience a while ago and decided to wait for it to cook a bit longer :)
