Oddly, exporting to chaotica from Apo7x works, but not trying to manually import a saved flame file. Still, it's up and running, and seems to be working well so far 
Gonna be leaving a simplish render up through the night, see how it comes out (2 linear triangles, a 3rd triangle with 1 linear3d and 0.125 spiral, a blur variation somewhere in there and a slightly increased filter radius, shouldn't be anything in there to break Chaotica)
Also, Apo seems convinced I'm using a version prior to 0.3 - guess that's an issue with it rather than chaotica, and doesn't seem to have had an effect on the render.
