Selecting Upstream conflicting with Node pop-up menu

Sorry for the noobish question. I have learnt that to select upstream, you would CTRL + COMMAND and click – except that this seems to also bring up the nodes pop-up menu hence deselecting the nodes again. Any solutions to this? Cheers. Running NukeX 6.0 on Snow Leopard OSX.

PointCloudGenerator Export Question

Hello gents hope you all are having asplendid day. Ha… yessum. Well I am in a sort of perdicament here.

I have got a dense point cloud from the point cloud generator and need to export not only the point cloud, but i need all the points to be exported as spheres and have the same RGB information that is stored in the point cloud generator node. Either python or a gizmo would work as long as I am able to render out an .fbx with all these points with the correct RGB information.

Any information would be greatly appreciated.:D:D

Constant crashing at a certain point in your script

Hi all,
I’ve encountered this problem a couple of times where when playing back (or even jumping to) a certain place the timeline Nuke will crash. It seems as if it’s a problem with caching the material, it will cache once fine then when it plays off the cache as soon as it gets back to the frame I started the cache from it’ll crash. All the Terminal says is segmentation fault. It’s a more common behaviour (I haven’t tested thoroughly) when viewing the comp as opposed to just the source.
ANy one encountered this/might have a solution?
Thanks
Andrew

getting the current node inside group nuke python

Hi all

I am facing the problem with getting selected node inside the group. If the selected node is main view i used nuke.selectedNode() but command is not working when the selected node inside the group. Ex: My selection node is "Write1" ie inside the "Group1->Group2" Then I want output as Group1.Group2.Write1.
In the render i use /usr/local/Nuke6.2v1/Nuke6.2 -X Group1.Group2.Write1 <scene name>.

thanks inadvance.

Selecting or returning the node name

Hi,

Is there any specific way to return a node selected inside a group?

I’m able to select a node inside a group since I know the name of the group in which the node is.

But how do i do the reverse, like if i select a node inside a group – i want to find out which group it belongs to.

Thanks in advance.

Increasing Performance in Nuke 6.2v1

I’m having a problem with Nuke 6.2v1 where it is freezing up my Windows machine for a few minutes, and wanted to know if there is anything that can solve this

I have a Dell Precision T5500 workstation with 12-core Xeon processor and 24 GB RAM running Windows XP x64 SP2. I set the total paging file size to 24GB

The problem happens when Nuke is doing an operation and taking 23 MB of memory according to Windows Task Mgr, but I see the Virtual Memory size of the NUke 6.2 process to be 8 GB

Thanks

Version
Nuke 6.2v3

This is a maintenance release of Nuke with feature enhancements and bug fixes.

Release Date
22 March 2011

Supported Operating Systems
• Mac OS X 10.5 “Leopard” and 10.6 “Snow Leopard” (32- and 64-bit)
• Windows XP SP2, XP64, Windows 7 64-bit
• Linux RHEL 5.4 64-bit

New Features
There are no new features in this release.

Feature Enhancements
• Several improvements have been made to the file browser. • BUG ID 12177 – CornerPin: Added an invert button for swapping the
from values to to values and vice versa.
• BUG ID 14032 – R3D reader: The gamma curve control’s default value
was fixed to ensure compatibility between Nuke versions.
• BUG ID 14782 – Python: It’s now possible to add a channel using Python.
For example:
nuke.Layer(‘myLayer’, [‘red’, ‘green’, ‘blue’, ‘alpha’])
• BUG ID 15018 – Python: Added three callbacks nuke.addAutoSaveFilter(), nuke.addAutoSaveRestoreFilter(), and nuke.addAutoSaveDeleteFilter().
• BUG ID 15779 – Python: Cascading menus were added for enumeration knobs. For example:
knob = nuke.CascadingEnumeration_Knob( "Knob" , "testknob", ["test", "menu/menu a/one", "menu/menu a/two"] )
• BUG ID 16106 – Python: Added a filenameValidate callback for validating file names in Write nodes.
• BUG ID 16165 – Python: Added a Python Flipbook example on using RV flipbooking tool. For more information, see p. 573 of the Nuke User Guide.
• BUG ID 16293 – File browser: The Next button now has a tooltip.

import nukescripts
nukescripts.setFlipbookDefaultOption(‘intermediate Format’, ‘cin’)

Applying Grain with a Grain Plate

So I dislike using the ReGrain node because I can’t control the amount of grain in the highlights and dark areas of the plate. The high and low gain controls don’t work that well cuz you can’t tell them what is high and what is low.

So I made a grain plate using the DeNoise on one of the plates I’m working on. My problem is I’m unsure of how to apply the grain to the plate. I’ve taken a Luma key and applied the grain in the areas I want but I’ve tried pretty much all of the different operations in the the merge nodes and nothing works. The best was just using an "over" node and turning down the mix but then it still effects the blacks in the plate.

Anyone know how to apply grain from a grain plate onto another plate? (and no not sampling the grain plate with a ReGrain node :P)

Bending with Arri Alexa

Hi everybody !

We’re on a prod who use the camera Alexa and we have some bending problems when we re-created gradients. Does anybody meet this problem before ? What could be the solution ? We have tried to render gradients in tiff – 16 bits but it doesn’t fix the problem. The bending only appears with the rendering.

Thanks a lot ! 🙂
