Description
I'm testing the upcoming Mandelbulber release 2.27.

The inner sphere is shaded using the new Sub Surface Scattering feature, in this case the settings have been tweaked to allow a very good transparency and "see-through" effect. SSS also renders quite fast.

Mandelbulber 2.27-Dev OpenCL Multi GPU render
Fractal formula: Pseudo Kleinian - Mod 4 + T>DIFS Hexgrid2

Image size: 4K - 3840x2160

Some Post Processing in PS

Thanks for watching!

Note: Mandelbulber version 2.27 required
