procedural Level Bar - Substance Designer
The Transition is controlled by a Histogram Scan exposed slider that affects the color and the emission outputs. :) the histogram give some depth to the edge of transition faking a nice volumetric effect (inside it).
Modeling some Fantasy-like pieces/frames/ornaments in Substance Designer.
Things like that are perfect stuff to create/design in SD because you can generate a good amount of iterations tweaking some parameters very fast. ;)
In this process, i even made an interactive texture with a kind of "energy bar" slider that i can animate using a with an exposed parameter. :) Pretty cool.
