Not sure if this is a bug or if I’m mis-using something, but when I try to use the position feedback parameter on a Flex emitter the particles freak out.
The data inside the TOP seems fine, and it works ok with velocity feedback.
I would definitely appreciate any fixes or work-arounds.
Thanks!

UPDATE: Not a complete fix, but setting smoothing on the NVidia Flex Solver to zero keeps the particles from flying off.
UPDATE2: I’m guessing that the Laplacian smoothing is happening inside the feedback loop, when it should be further down the pipeline–just before rendering? Very small non-zero smoothing values don’t cause the particles to explode either.
