Python: singleLineInput that depends on a CheckBoxBoolean … how do you do?

Posted in: NUKE from The Foundry
Hi Folks,

I have a singleLineInput that I would like to activate or deactivate depending if a CheckBoxBoolean is set within the same panel.
I imagine the deactivation to be something like the typical grayed out field.

Is there a simple way of doing this?

Thanks in advance.

Vector Displace on just pixels?

Posted in: NUKE from The Foundry
Hi all,

I’m working on a shot that could be solved with a tool similar to what I’ll describe:

Using vector analysis of one clip of images (a sequence of a guy moving a little bit in-frame), I want to displace the pixels of another clip (or just a single frame) so that it looks like it is glued to the motion of the pixels that were vector analyzed.

Basically, I thought I could use the new Vector Generate node to then pipe that data to move the pixels, but haven’t yet found a way to a make that work.

The end result is that I am trying to correct some makeup errors on a bald cap by painting a clean version and letting the motion of the pixels of the clip distort it along with the original so that it covers it up as he moves. It’s kind of like a CG tattoo, but it’s only for about a hundred frames or so, and he doesn’t rotate.

Does anyone know if I am on the right path, and if so, what next steps might be? I analyzed the source clip, painted the makeup error out, and am stuck at that point.

Thanks for any help you can provide!

[Nuke6] Import chan from script

Posted in: NUKE from The Foundry
Hello folks,
I’m working on a python script that imports cameras from a stereo maya scene.
It worked all well since I was using Nuke5, but now that I’ve upgraded to Nuke6 I have the following problem:

These lines used to work:

Code:

camera_lx.knob("import_chan").setValue("import_chan_file " + chan_path)
camera_lx.knob("import_chan").execute()
camera_lx.knob("import_chan").setValue("import_chan")

But… the "import_chan" knob on the Camera node is not working anymore!
Now it’s an "Obsolete_knob" and I can’t execute it.

To import a chan manually, I have to click on "file_menu" icon and then "import chan file".. But I don’t have any idea of how this can be done by script!

Can you guys help me?

Thanks in advance,

Dora

Nuke on HPxw9400 workstation

Posted in: NUKE from The Foundry
Hello there,

we want to set up a nukestation on mentioned hp workstation.
Since I dont like windows too much I personnaly would prefere Linux centos (since foundry recommand it…)
My question is, if anyone has experience setting up such a nukestation and if all needed drivers and such are available for this os…
Can anybody give some opinions about the performance on linux compared to the other os since I heard nuke runs fastest on linux.
I would also need to install ps on this system but it only runs on whine? Is this a big deal or does it run stable and is usable?

Any pointers are appreciated…

Problem with changing default values from dropdown menus in 6.2v1

Posted in: NUKE from The Foundry
hey guys,

i have set some user values in my menu.py for ‘filetype’, ‘datatype’, ‘compression’ in the write node and ‘cliptype’ and ‘feathertype’ for the roto node.
since 6.2v1 it appears that values which are choosen from a dropdown menu, can’t be changed since ‘compression’ and ‘feathertype’ remain the default ones. can anybody confirm this behaviour?

Lin 2 log

Posted in: NUKE from The Foundry
I have been asked to convert my comp from linear to log dpx files. Can I just put a lin2log node at the end of the pipe? Does this node even exist? If so what do I set the colorspace to in the write node?

Thanks!
