DarkTree 2.5 is an advanced
procedural shader authoring tool. By
combining any of 100+ procedural
components into a texture tree, you
can interactively create
photo-realistic textures, surface
shaders, and animated effects
The textures generated by DarkTrees
are calculated in 3D space instead of
being derived from bitmaps. Because
of this, DarkTree materials can be
rendered with full detail at any size,
map seamlessly onto any shape, and
can be easily changed during the
creative process (or over time for
special effects).
