  • The Size Interpolation parameter determines how the main Brush Source is resized as it gets smaller.

     

    Min means that a nonlinear Minimum Rank FIlter is used.

     

    Generate at Size means that if it's a computational brush, the actual brush generation code is run at the smaller brush sizes.

     

    What this is all in reference to is that for Brush Source types like the computational one, a cache of different sized brush images is generated in memory. The drawing then takes place by using one of the cache images, as opposed to recomputing the brush image on the fly as drawing takes place.

     

    Generative and MSG Live Brush Source aren't pre-cached, they draw live.
