For a long time I have been working on making various celestial effects directly in-Vue using only procedural materials to create stars, planets and in this example - nebulae in hope I could bunch them all as a pack and try to sell it as a resource on Cornucopia3D (which is lacking in any worthwhile space-stocks that don't look fake or use memory-guzzling texture-maps).
Big advantage is this rendered fast around 5 minutes at 1600x1000 and used up little memory...so little that the Vue scene file was just under 300kb
This image is rendered diretcly out of Vue and no image-based materials were used on anything and not tricky or slow volumetric materials either (except on the planet atmospheres but they were thrown in there to make it less boring). I might reveal more as I continue to refine the pack's other content
