Please is it possible to import an EPS file from illustrator and still have it editable in SA?
Any of the turbulence generators can be spatially modulated. If you look in the Texture Synthesizer, you see a large number of modulator options for the editable parameters. There are also additional parameters for the source of the modulator. So you can modulate the visual properties of the generated turbulence in a spatially localized way. Using the contents of the source image, the existing canvas, etc.
The MSG turbulence generators are similar to the Texture Synthesizer. They are generating procedural texture fields that can be spatially modulated.
Here's a tip that discusses Temporal Generators and how you can use them to modulate parameters in a MSG preset.
Please what are turbulence generators?
The Texture Synthesizer generates a procedural turbulence texture field. The AdvTurb and GenTurb MSG processor options generate turbulent texture fields. The procedural options in the paint synthesizer for background texture and procedural brush type do the same. As does the SimpleTexture ip op effect.
So they are all generating multi-octave fractal noise fields. Most of these effects offer 3D texture field options in addition to 2D. So then you can modulate depth in the z axis to add spatial structure based on a modulation source (like the source image but could be other things).
Have you tried using your image folder as an image folder brush in Studio Artist's paint synthesizer with a tiling paint preset?
