The Texture Synthesizer is an older Studio Artist operation mode that can be used to generate procedural texture fields and texture based effects. While it is superseded to some extent by MSG these days, there are still lots of interesting visual effects you can generate with it. The Texture Synthesizer is designed so that the local properties of the generated texture field can be modulated by the current canvas or source or other layer images. So by using it multiple times to recursively process it’s previous output you can build additional organic complexity into the resulting generated texture.
Let’s take a look at a very basic texture synthesizer preset. The control panel settings below are based on a slight modification of the Default : General : A Default texture synthesizer preset. I slightly reduced the Directionality parameter in the Spatial control panel to make the generated texture field slightly less directional (to better see the recursive modulation effects we are discussing in this post).
