About Rebelle

Rebelle mimics the way natural media interacts with the canvas and itself. Users can paint, smear, re-wet dried colors, blow wet washes across the paper, tilt the paper to create water drops and runs and create countless fantastic watercolor effects. Wet tools — watercolors, acrylics or ink pen — can be combined with pastels, pencils, airbrush many other dry-media tools and effects.

Features include:

  • “Ultra-realistic papers”: you can use not only textured paper backgrounds, but also an imitation of real watercolor papers, some of them with deckled — rough and irregular edges, including: hot press, cold press, rough, Japanese, canvases and others.
  • Watercolor simulation code re-design: To adapt to the new papers, a watercolor simulation code has been rewritten to be even more realistic than ever before.
  • A new DropEngine: aAn implemented engine enables more realistic paint drying and dripping. You can blow drops and create watercolor dripping effects.
  • A Masking Fluid layer. The masking fluid allows you to paint freely over the masked area.
