Animation (tweaking) with brushes work great with Brilliance.
One example:
You can simply load anim into Brilliace, cut animbrush (set how many frames you won to cut), and use this animbrush in pseudo 3D animation tools, with fade in, fade out,selecting first frame, last frame, preview, speed, etc. After that you can save tweakins settings and use again in another animation.
And all this is very simple to do with brilliance paint soft like Brilliance. ;-).
On my A1200 I have one great animation created with Brilliance/Lightwave/VistaPro and packed with Scala.
Looks great on AGA amigas, and I pack all animation with Brilliace. (170 Mb anim8 format)
