Hi all,
My work mainly involved with compositing and need to generate high
resolution images from cop. I set to maximum resolution at
preferences>compositing>cooking, say at 20000x20000, however, the image at
composite view can only display up to around 16000 pixel. Is it because of
my display card capacity? Mine is NVIDIA Quadro K2000, should I get a higher
performance display card? Any recommendation? I'm using Houdini 14, window
8.
Thanks!
Kind regards
Herman

1:41 p.m.
i think its the resolution limit
by default its 10k
go to preferences>compositing> cooking

Thanks Zoran, I already did set the preferences. Would like to know if I
need to upgrade my display card. I'm using nvidia quadro k2000.

Hey Herman,
I am not 100% sure if your images are not displaying due to the graphics
card or not, but I deal with high resolution stuff all the time and will
say the k2000 is a pretty crappy card in many respects. You would be better
off with a geforce 970, but if you are consistently working with images
of that scale, I would want at least a Titan or a newer k series. I have
both. K5200 and. K4000 but I need the K's really only for certain things,
otherwise Titan for sure.

Thanks Jordan, will go search for titan or quadro k 5200. Since I'm using
the cop to generate very large images for wall size poster.

Are you able to cook and write out those files using a Composite ROP at
that resolution? That would rule out whether it's display limitation or
not.

Thanks Edward, I did manage to save the image by using right clicking at the
node, for some reason when I use the rop output, the image generated has a
white wash on top.
If I set the resolution to 25000x25000, somehow I manage to save the image,
but photoshop not able to open it, most likely its too big of a file.
Cheers

The other thing that you might want to watch for are maximum
resolution/size limits on the underlying image format that you're saving
to. I think Photoshop should be able to handle file sizes that big.

I think the best way to test is to create and export your image from
Photoshop and make sure that it can be reloaded properly back into
Photoshop.

Targa stores the image resolution in a 16 bit integer, so the maximum
resolution is 16384 by 16384.
TIFF stores its resolution in a 32 bit integer, so the max resolution
for TIFF is 4294967296 by 4294967296 (same as JPEG).
PNG and OpenEXR are 2147483647 by 2147483647.
If you save the image from a ROP and open it with mplay, does it
display properly? Does it display properly if you load at 50%
resolution (i.e. mplay scales the image as it loads, before it
displays it).
The white-wash might be an artifact of the image display, rather than
an artifact in the image itself.

Dear Mark,
The Mplay play properly on tiff image without the white wash. Now I use the
rop to render the image in jpeg format, since only the jpeg do not appear to
have white wash when I open it with photoshop. Then in photoshop I save the
image in tiff format for future printing.
I assume using the rop to render in jpeg then use photoshop to save in tiff
will not lose the quality right?
Many thanks!
Cheers
herman

Targa stores the image resolution in a 16 bit integer, so the maximum
resolution is 16384 by 16384.
TIFF stores its resolution in a 32 bit integer, so the max resolution for
TIFF is 4294967296 by 4294967296 (same as JPEG).
PNG and OpenEXR are 2147483647 by 2147483647.
If you save the image from a ROP and open it with mplay, does it display
properly? Does it display properly if you load at 50% resolution (i.e.
mplay scales the image as it loads, before it displays it).
The white-wash might be an artifact of the image display, rather than an
artifact in the image itself.

The other thing that you might want to watch for are maximum
resolution/size limits on the underlying image format that you're
saving to. I think Photoshop should be able to handle file sizes that big.

I don't know if jpeg is a good idea since it's a lossy image format.
However, I guess a JPEG Quality of 100 isn't too bad.

Dear mark and Edward,
The image I need is for large poster printing, so I need very high
resolution and do not need alpha at this time. If I do, I would do as you
suggest rendering an alpha plane separately.
Thanks.

Hey Herman,
Not exactly an answer to your question re gfx card, but one that might help you get things
done with your current setup.
Couldnt you render out tiles and stitch them back together in Photoshop?
I.e. Instead of rendering the complete 20000x20000 image in one go, split it up in lets
say 4 10000x10000 (upper right, upper left, lower right & lower left) images.
Not the most elegant way, but it should get things done :)
Good luck
Ron

Hi ron,
I did manage to render the whole image in tiff, by not pressing on display
so as not to take up virtual memory, then drop a rop output and render the
node by setting it very high resolution with lowering the raster depth to
say 8bit, since I do not need alpha channel.
Your method also works too by cropping it.
Thanks.
Cheers
herman

Hey Herman,
Not exactly an answer to your question re gfx card, but one that might help
you get things done with your current setup.
Couldnt you render out tiles and stitch them back together in Photoshop?
I.e. Instead of rendering the complete 20000x20000 image in one go, split it
up in lets say 4 10000x10000 (upper right, upper left, lower right & lower
left) images.
Not the most elegant way, but it should get things done :)
Good luck
Ron

New subject: uv transformation - motion blur
Hello all,
I wonder if I'm overlooking a straight forward way to render a sliding texture with
motion blur?
I'm working on a shot for a spot where the paper/tape of an adding machine needs to
flow out quickly ?. but in stops and starts.
I could use a creeping surface so I can compute velocity?.
But sliding the UVs feels a lot lighter and quicker to work with.
Just not exactly sure how to convert that motion into some velocity value that mantra will
recognize.
I've addressed this issue in the past ( in a crunch ) just by blurring the texture
horizontally.
But the required stops and start in the paper flow here make that a bit more cumbersome to
deal with.
Anyway ?? thanks as always for any thoughts.
Larry

Hi,
Wouldn't selecting "Deformation Motion Blur" on the geometry take into
account the movement of the texture? Not sure, but worth a try.
Thanks,

I'd move the paper into texture space using point sop or vex, then place
a piece of geo above it referenced to whatever it is that you are using
to move the texture, calculate v, then attribute transfer it back to
your paper, then move this back into world position again.

Assuming a multi-segment deformation blur doesn?t work (using the multiple segments not
for positional changes but for shader changes, which /might/ work in pbr), you could
create two or three sets of frame sequences, each with different amounts of horizontal
blur, and just map the speed of the paper tape to the sequence with a vaguely appropriate
amount of horizontal blur.

Couldn't you also just try and use the offset speed to compute v? I'd imagine the
sliding has animation right? So it can start and stop. Well, you can compute the
difference in offset between 2 frames, normalize and multiply arbitrarily for the amount
of moblur desired? Of course using "v" means you have to te the geometry to use
geometry velocity for motion blur

Thanks for the quick feedback everyone.
This certainly gives me some options to work with.
Right off the more direct simply options ( checking "geo velocity blur" on )
and the like didn't seem to work.
With ray trace rendering anyway.
I am getting some form of motion blur playing around with more involved methods, But
it's not quite right yet.
I thought I had it at one point ?. but then I realize I was still getting blur even when
the animated texture was at a hold point.
Got to give it a bit more time but I think the idea Emanuele seems to be pointing to below
is on the right track for my needs.
If I can get this method working correctly I think it will give me the procedural
flexibility I'm looking for ?. especially as
I continue to revise and tweak the speed of the motion moving forward.
Thanks again for all the input everyone.
Very much appreciated.

Thanks again everyone for the helpful input to point me in the right direction.
I was able to circle back today and get this working in a fairly automated way ?. which I
was hoping for.
Base on Emanuele's process outlined below I was able to fetch the animated
"offset" channel from the uv texture SOP into CHOPs.
?. and then drop on a slope chop to calculate acceleration/speed.
I then followed that up with math and limit chops to clamp/normalize the value to an
appropriate level for velocity.
Export that back to a point SOP to add velocity( in the proper direction) and I can now
render with motion blur based on the motion of the sliding ( stopping/starting) UVs.
Thanks again. I'll need to store this away for future use.

I am thinking the white wash could be a gamma thing. Some of those formats are linear,
and not 2.2 gamma, so depending on what he did and how it was viewed it could come out
looking washed out.

Targa stores the image resolution in a 16 bit integer, so the maximum
resolution is 16384 by 16384.
TIFF stores its resolution in a 32 bit integer, so the max resolution for
TIFF is 4294967296 by 4294967296 (same as JPEG).
PNG and OpenEXR are 2147483647 by 2147483647.
If you save the image from a ROP and open it with mplay, does it display
properly? Does it display properly if you load at 50% resolution (i.e.
mplay scales the image as it loads, before it displays it).
The white-wash might be an artifact of the image display, rather than an
artifact in the image itself.

Your card is likely limited to a 16K 2D texture axis size (16384x16384).
To support higher resolutions, we'll need to display these images via
tiling (multiple textures per image). You can reduce the cook display
size to 50% in the Composite View to avoid this limitation (menu in the
Composite View top toolbar; will currently say "Full").
Cheers,
M.

Hi all,
My work mainly involved with compositing and need to generate high
resolution images from cop. I set to maximum resolution at
preferences>compositing>cooking, say at 20000x20000, however, the image at
composite view can only display up to around 16000 pixel. Is it because of
my display card capacity? Mine is NVIDIA Quadro K2000, should I get a higher
performance display card? Any recommendation? I'm using Houdini 14, window
8.
Thanks!
Kind regards
