With this update come really many new things:
- introducing wall-objects: helping to combine classical architectural elements with fractals
- a collection of new sky objects
- a collection of new ground objects
- a large collection of new procedural textures
- the ability to use flame fractals as HDRI sky for interesting lighting effects
- the ability to use flame fractals as procedural texture for even more texturing options
- fractal formula transforms have been unified: they work now the same in single fractals as well as inside hybrids, and you edit them at the same place
- some new (optional) generic fractal transforms, which work for any formula (watch out for the "Fractal Transform"-tab)
- variation-deforming transforms can now be defined for any formula as well, either as pre- or as post-transform
- the preview-renderer was re-written to handle "heavy" scenes much better
- procedural textures may be applied to fractals as well
- some bug fixes and lot of other smaller things
Happy rendering!
