Hi I edited this bug report because it's apparently due to bad module(s) in the user/library/applicationsupport/vuo/modules folder. I removed that folder and it opens ok. So... I guess the thing would be to modify the next version of Vuo so that it doesn't crash but instead blocks the bad nodes and gives a useful error message.
This is a composition created for use in Resolume (etc) as an FFGL plug. It's designed to be used on a channel with a moving image and a lot of clear space (ie zero opacity). The feedback fills up in the clear space and then is automatically masked so that it has a "decay" and you can still see any background layers beneath.
I'd love some feedback (ha). I suspect this qualifies as a thoroughly noob composition. I'm sure there must be simpler ways of doing this.
