I just installed Linux on my PC yesterday and tried to make Nuke worked on Linux…
I’m so confused about what they said on the Nuke user menu. I am wondering if someone could clearly show me step by step about Nuke installation on Ubuntu 10.04.
My question is:
If Nuke on Linux must be installed under the "root" directory, not the "user" (for example, I give it a name: zhimama) ? I tried to install Nuke under "zhiamam" directory, after finishing the installation I couldn’t install license. The user guide says that Nuke will be installed under the /usr/local/ directory. I guess it means Nuke should be installed under "root" diractory not "zhimama" directory.
Please correct if my understanding is correct. If it is, could you tell me how to access to "root" directory step by step and install Nuke ? I am really new to Linux OS…
Basically, My mehtod was that I downloaded and uncompressed Nuke files and put it on the desktop my of computer.
The name of that extracted file folder is called: Nuke6.1v1-linux-x86-release-64
I followed Nuke user guide to type commands in terminal but it showed me error…
I guess if I install Nuke successfully, it would be installed under the "root" directory. However, I used a simply way which was just double click the installation icon and installed it but it showed me my Nuke would be installed under "zhimama" directory, not the "root".
I am wondering if someone can show me how to do it in a proper way so Nuke can be installed at:
mkdir /usr/local/Nuke6.1v1
Thanks,
From the info I’ve gathered so far, doing environment reflection in Nuke is limited to throwing env. reflection onto all objects/whole image based on a universal BRDF (Phong or Blinn) regardless the scene objects own BRDF (ex. car’s paint, rubber tire, and chrome with varied glossy reflection).
I am wondering if it is possible to do accurate environment reflection based on materials BRDF in Nuke (as interactive as possible). For example, if its is possible to bake (or render a pass) environment reflection look-up of various materials in a scene into textures/point-cloud/Ptex or any form of data structure, then one can use it as a lookup to the environment map to get "per-material" environment reflection in Nuke? Kind of like a reflection vector pass but with the glossiness information of various materials contained for env. reflection look-up.
Hope my question makes sense and correct me if any info I mentioned is incorrect.
cheers,
Jason
Just my thought.

Now if i go inside the Nuke, in script editor , if i want to change the format i have to type : nuke.toNode(‘root’)[‘format’].setValue(‘HD’). As i know the Node name should be ‘Root’ not ‘root’ but this time, ‘root’ is the one which is working , and ‘Root’ is not acceptable.
2. Also how can i get the global format setting by using python. I try these syntax with no luck :
nuke.Root()[‘format’].value()
nuke.toNode(‘root’)[‘format’].value()
the only way i ussually use is using nuke.tcl(‘value root.format.width’). But i’m just curious why that scripts is not working? in fact i can get value from other node using that syntax, for example : nuke.toNode(‘Text1’)[‘opacity’].value(.5) …..Can anyone help me?
3. How to lock the knob/parameter by using python script?
4. I found the nuke-python documentation is not friendly enough 🙁
thanx
