This update brings new fur/hair-controls which can be combined with any material. But, please note, that computing fur is a real heavy operation. Even compiling the shaders can take up to minutes! If you encounter GPU-timeouts during rendering, decrease tile-size and/or quality budget. But, it can give really nice results! Also, there are a lot of new procedural textures. To improve the handling in the user-interface, there is now a generic item-picker for textures, fractal formulas, primitives and deforming variations, which is sorted by categroy and also shows (for many of them) a preview-image. Some preview images are not good yet, or even missing, this will improve from release to release. And, again, the pre/post-transforms at formula-level where generalized again/more and there also more transforms available, like a variation-deform or spherical inversion. These work with any fract...
