shake notes

a collection of notes-to-self

motion blur:

shake’s motion blur by default blurs from the current frame’s position to the next frame, rather than current frame to both previous frame and next frame, ie, backwards and forwards. to get it to mblur both fore and back, you need to adjust the shutterOffset, or add this to shutterOffset:

shutterTiming * -0.25

now adjusting shutterTiming biases the offset to keep the blur centered around the current frame.

command line render vs. gui render:

to switch behavior between cli renders and working in the gui, use sys.runLevel. ie. to switch motionBlur quality to 1 for cli/farm renders:

1-sys.runLevel
or
sys.runLevel==1?0.2:1.0
