Beta 4.
I have a Pflow Position Object emitter and it’s giving me inconsitant results between scanline renderer/viewport and Krakatoa.
It’s offset the particles. Really odd.
I used a different shape, and I can see that it’s not just translated, but rotated as well.

Interesting.
I'll try to reproduce that from scratch, but it would be great if you could zip up that simple max file and send it to us.
I’m having a hard time reproducing it, but I have seen this once before. I’ll send you a file if I can.

My suspicion is that there is something funky with the transformation matrix
on the emitter or position object. The scanline renderer correctly accounts
for it, but we are missing it. It’s just a hunch, and I won’t be able to
figure it out until we can play with a reproducible example.
We’ll keep looking for it here, and I’ll log a basic bug report for it just
in case someone else runs into it.
Aha! Got one!
Excellent. Thank you for your persistence! I’ll grab this and take a look.
Got it.
Somehow, all your PFlow system elements (the Particle View, Particle Events etc.) got a flipped TM (just like when moving data to Maya ;o)
for o in (refs.dependents $‘PF Source 01’) do try(format “%.transform = %\n” o.name o.transform)catch()
returns
Particle View 01.transform = (matrix3 [1,0,0] [0,0,1] [0,-1,0] [0,0,0])
PF Engine01.transform = (matrix3 [1,0,0] [0,0,1] [0,-1,0] [0,0,0])
PF Source 01->Event 01.transform = (matrix3 [1,0,0] [0,0,1] [0,-1,0] [0,0,0])
OK
Krakatoa should not have looked into these matrices (Scanline doesn’t), but it did and flipped the particles.
For now, the line
$‘PF Source 01->Event 01’.transform = matrix3 1
should fix the scene.
We will look into the code when we come back to the office on January 2nd! It is definitely a Krakatoa bug, thanks for catching it!

Thanks, this was fixed this morning for the upcoming 0.9.5 build.
