Blender 2.7* OpenGL Viewport Space Scene
This is an exercise in creating multiple effects layers entirely in the viewport. The scene output was color graded and motion blurred in the VSE via a scene input strip and OpenGL render. Lens distortion created in post process rig and rendered in OpenGL.
All elements (planet, asteroid field, nebulae, star field, flare, lens bokeh, vignette... etc.) exist in one scene as a single composite. Lots of tricks going on here.
I'm thinking about creating a tutorial series called "Hacking the Viewport"... if there is enough interest. Anyone?
