Incendia is indeed one of those unique and boutique programs.
Arguably one of the very first 3D fractal generators, perhaps even Apophysis, it captured my attention back in 2009. Despite being somewhat of a pain to use, it possessed the ability to generate incredibly unique fractal geometry with volumetric lighting.
I would often use it in a similar manner to Cinema 4D, rendering out assets to be remixed later on in my workflow.
While I rarely utilize it nowadays, I’ve already built up a comprehensive archive of assets from my heyday of Incendia use. It remains a cherished part of my artistic journey.
