Thanks for the answer

*Hi all,*
Just to follow up. I spoke with the folks at Imagineer and they said
the issues with distortion maps were fixed in v4, but it's possible
that exr's are still affected. Tiff's are being rendered correctly
from Mocha Pro v4 at 32-bit and the aliasing problem has disappeared.
Cheers.

I agree, it /should/ be 32-bit, but I don't see that option inside
of Mocha and nuke is giving me 16-bit half-float metadata on those
files. Time to contact imagineer!

You should use 32bit exr, that should solve your problem, I
used to get that a lot when working with STMAPS, but once I
started using exr at 32bit, life became much much better

I forgot to add that in this scenario I would do a deep
recolour with the UV remapped image onto the deep opacity
it was extracted from, and then I get the transparency/AA
back.

Thanks for bringing up deep UV maps again Frank. I am
so looking forward to being able to do true deep
camera projection with just a deep opacity image and
Nuke camera as the input!
I know some places have the tools, but as a workaround
with some of the benefits, I've deep unpremulted the
opacity out, flattened it then used a regular STMap
node. This saves the need for an unfiltered data pass.
Then I added the motion blur back in with VectorBlur,
using the flattened deep opacity as my Zdepth source.

With the "flat" STMap you get nasty edges in those
areas whereas a DeepSTMap could solve that (with
the right image data coming in).

Wow, that would be a great solution. I suppose
the alternative is to do each object UV
separately and then comp them after the STmap.

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

I wouldn't think it would cause
aliasing. I 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?
