How do i do an inverse transform on a tracker node in nuke ?

Hi everybody-
I’ve been going hard at Nuke and Python for the last week- and I’ve had a couple of problems I can’t seem to solve.
I’ve been going hard at Nuke and Python for the last week- and I’ve had a couple of problems I can’t seem to solve.
1. – How would you go about listing all of the nuke.env variables? Simply
"print nuke.env()"
or
"for i in nuke.env() print i"
doesn’t work-
and I can’t seem to figure out how to list the contents of some dictionaries in Nuke.
2. – My second question is: where do you place your "init.py" or "menu.py" files for starters?
On my windows XP machine it is in "Documents and settings\<user>\.nuke\ " which is no problem.
However I’ve looked at multiple other machines that are identical- and their .nuke folder doesn’t exist, (except- perhaps C:\.nuke\ which doesn’t work either)
So do customize multiple Nuke workstations- is it possible to find a path within Nuke to that user’s .nuke folder containing init.py and menu.py?
Thanks for your time!

thats the question, I have many 3d characters moving and doing things so they render with motion blur. so should I render them to work in nuke in stright or premultiplied mode?
thanks

SplineWarp freak out
Posted in: NUKE from The FoundryI’m using the splinewarp to do a morph between an adult and a child and I’m running in to a very strange problem. At seemingly random frames during the morph the source image goes crazy (as is very evident in the attached screenshot). I cannot seem to figure out why this is and any help explaining how to rectify the problem would be wonderful.
The basic setup I have is a source and destination image with corresponding splines. Each set of splines has a beginning and end keyframe to account for minor movement, and the morph itself is done with the distortion and blend sliders. Overall the morph looks fine but on random frames the source distortion freaks. The splines themselves look fine on these frames it’s just the image that changes.
I don’t really have much experience with morphs and have no idea what could be causing this. Any ideas? I can post a video clip of the problem if that’ll help anymore than an image.
Thanks,
Jeff

hey folks,
Trying to wraph my head around Python within Nuke.
I am trying to predefine a Shuffle node so it spits out Red in all the output channels – when doing so manually i get the following output in the ScriptEditor:
Trying to wraph my head around Python within Nuke.
I am trying to predefine a Shuffle node so it spits out Red in all the output channels – when doing so manually i get the following output in the ScriptEditor:
Code:
print nuke.selectedNode()
# Result: in rgba
in2 none
red blue
green blue
blue blue
alpha blue
black red2
white green2
red2 blue2
green2 alpha2
out rgba
out2 none
The output makes sense but I am having a choke trying to formulate it via python – so far i’ve got this written to create the node and connected but not sure what the syntax would be to achieve the desired result.
Code:
def redChan():
redChan = nuke.createNode("Shuffle", inpanel = False)
redChan.setName("Red Chan Shuffle")
redChan.setInput(0, shadowInvert)
redChan()
A push in the right direction would be much appreciated – and let me know if I am not making sense.

I know in Bezier we can choose the autokey to set it .but how about anther ?like color correct and transfrom ?
i know in shake ,i have different ways to set keyframe. i really think it is a bad design. because some keyframe is automatic some is not .and they in different area.
i dont know how about nuke ,maybe is get better?
thanks, can i said keyframe in engilsh:confused:?

this is very interset thing that every nuke user have different "nuke table" idea.
from the idea ,i can know who use shake before ,who use autodesk combustion before .
and some nuke table is very nice for nuke workflow .
but i am not a good nuke user now ,so i want to know more about nuke .
could you like show your nuke table? and tell me your custom？
ok, let me first, i am shake and avid media illusion before .
so ,this is my "table".

by the way ,how can i said the pic ?can i name it is "nuke table"? could you like
tell me what is right one ?
thanks~:cool:

Hello,
If I have a image sequence rendered @ 720×405..
then apply the camera shake node..
will excessive shake cause the 720×405 edges to become visible?
how does this node calculate shake?
Thank you,

Merging after IDistort node
Posted in: NUKE from The FoundryHi.
I want to distort an foreground element and merge it over a background. For the distortion i used the IDistort node following sathees example he posted in this thread: http://www.vfxtalk.com/forum/create-…ke-t16095.html.
The image that controls the distortion is a small .png with horizontal lines. As long as i don’t merge the distorted image over the colorbars it works fine. But when i merge it in "over" mode, the foreground isnt’t opaque anymore. I searched in the documentation and internet but couldn’t find a sollution to this. It would be great if someone could help me out.
I added an image to make it a bit clearer.
Thanks in advance.
