Smoke Simulation Renders!

17 Nov 2018


Smoke simuations have been an area of interest of mine for a long time. In the past, I didn’t have the ability to render them since my hardware was inadequate to do it in a reasonable timeframe.

Smoke Tower_Cycles_nodesOne tweak that was particularly intriguing for me here was creating a thick, defined smoke density. I experimented with contrast and gamma node inputs going into the volume absorption and volume scatter nodes.

I continued to experiment with a mix shader node allowing for fresnal and layer weight nodes, allowing me to mix an emission shader on the edge of the smoke volume.

All of rendering was done in Blender. Some editing was done in GIMP, and some filters were used in certain images in the Microsoft Photos app.
