Just started experimenting with Touch and still learning a lot! Trying to make a “breathing” or gently pulsating sphere and would appreciate some help.
I’d like the Uniform Scale to fluctuate slowly between a small range and was wondering if there was a Python expression, which I thought it might be
op('moviein1').par.cue.pulse()
(but maybe ‘sphere1’ rather than ‘movie1’?) or a pulse node that reads to it? If so, would appreciate some pointers on how to do it. If I’m completely off base, let me know too!
a trigger chop would give you an attack-decay-sustain-release type of value when pulsed. An lfo CHOP can give you sine waves, or ramp… a noise CHOP can give you a random value, the animationCOMP can give you any animation curve you would like…etc.
Any of these value can be referenced (python) or exported (green link) to the scale of a transformSOP or a geoCOMP
you could also animate the amplitude of a noiseSOP wired after a sphereSOP (and plug an attribute create sop for normals recalculations)
Learn how to reference values, check out all the snippets, and look for tutorials
