Slightly OT but somewhat related (especially to Ryan's post):
This is why a DeepUVMap node would be great. With that you can render
deep ST maps from whatever software and have high quality STMap workflow
in Nuke without any aliasing in areas where geo overlaps itself.

Maybe there's anti-aliasing on the edges? If we use UV maps, we make
sure there is no filter when rendered, or you will get junk on the edges.

What image format are you using? Mocha Pro will output 32-bit
float distortion maps as long as you write to a format that
supports it. I know Mocha supports tif/dpx for sure which would
both work, I'd choose exr if it was available but haven't used
Mocha in quite a while.
The loss of precision at 16-bit may not seem like a big deal but
it nearly always causes artifacts.
Ripped straight from Imagineer systems documentation:
Distortion maps must be 32 bit floats, so TIF or DPX will be
the best options

I've tried centering inside of mocha using it's 'calibrate
center' method, but it didn't seem to affect the image.
Offsetting in nuke does make it a tiny bit smoother, but I
think that's because the image is being filtered by the
transform. Hmm.

16-bit does have a few bits less of precision (pun

haven't used mocha extensively, so I can only guess. It's
not one of those cases where you have offset X and Y by
0.5 pixels or something?

Mocha seems to kick out 16bit distortion maps and I
don't see any options to up that 32bit. When I'm using
the maps in nuke I get really hard aliased edges.
Blurring the map 3 pixels seems to help a little.
Anyone have luck with smooth transitions from mocha
distortion maps?
