Point Density Magical FX, our training and template package for magical FX for the Cycles render engine has received an upgrade! It now includes a brand new tutorial and template on a burning logo (which works with any kind of images), upgraded demo files in the pro edition, an updated documentation of point density and more.
The video below shows overview of the new effect and demo files.
In case you already have it just re-download. Otherwise check out the entire package here.
