Procedural Nebulae V

Naturally, I can't leave well enough alone!  Attempt IV was pretty cool, but it obviously lacked volume.  No surprises there: it was 2D.  Here's my first attempt at volumetric light inside of the same type of nebula as shown in the previous post.  I'm sure it will get better over time, but already you can notice a much better sense of volume, softness/cloudiness, and of light transport.  Light is correctly modeled using emissitivity and absorption as it passes through the nebula. I'd say this is a pretty good amount of nebula-related progress for 2 days!!

This method is about as expensive as the current LT nebulae...but it looks way better...so I think it's safe to say this will be replacing them soon 🙂 I am very happy with these, and I think I would quite enjoy seeing them in the background!  All the parameters - softness, brightness, feature size, absorption, wavelength-dependence of scattering, etc. are all easily-tweakable to get a lot of different styles.

Oh, and looks like we also get clouds for free! 🙂
