Nuke for 64bit mac?

I am looking at getting nuke for mac but the Foundry website says 32 bit only. If my mac pro is 64 bit can I not run Nuke?

Thanks for the help

Randomly change a nodes tile_color and gl_color

Hi, sorry for the n00b question.

Is there a way to make a new Bezier gizmo that randomly assigns a different tile_color and gl_color?

I’ve been using python to make the new node, but can’t seem to hone in on the tile_color and gl_color attributes thru python. Also, don’t know know to make a random hex color in Nuke.

I’m sure there has to be a simple way to do this right?

Thankz

Reformat not Reformatting

Ok, this has always been a pain in my side.

I have a job that was originally comp’d 1k, but now it needs to be 2k. All I should have to do is set my project settings for the new size, and attach a bunch of reformat nodes below all the beziers to get everything working at the new scale. But…the reformats don’t actually reformat my beziers. They just scale up the bounding box and that’s it. What am I doing wrong here? Everything is at the default settings in the reformat. Any help you guys could give would be GREATLY appreciated. Because the thought of having to redo all of that roto on a Monday makes me a tad unhappy.

Thanks guys!

confused with tcl or python

Hey guys which language should i study Tcl or python coz its so confusing. nuke developers used both tcl & python. im facing problems in achieving what i want coz some functions are in python & others are in tcl.

Python, …, again (animationCurve and Lookups)

I’m trying to create a Lookup interface with 3 animation curves in it …
Here is my approach in python … but I don’t get any results …
Does anyone know what I’m doing wrong?

Thanks to all!!

———————————————————————————————————————————–

n = nuke.toNode("Grain3W")

#these are 3 floating point sliders
lowCurve = n[‘lowCurve’]
midCurve = n[‘midCurve’]
highCurve = n[‘highCurve’]

# create an AnimationCurve for the channel 0
lowCurve.setAnimated(0)
highCurve.setAnimated(0)

# access all animation curves for the knob
alowCurve = lowCurve.animations()
ahighCurve = highCurve.animations()

# set the animation keys
alowCurve[0].setKey(0, 1)
alowCurve[0].setKey(0.25, 0)
ahighCurve[0].setKey(0.5, 0)
ahighCurve[0].setKey(1, 1)

#creates the lookup panel
ll = nuke.Node.addKnob(n, nuke.LookupCurves_Knob("defCurve", "ranges"))

#here comes the problem: the result in python feedback is ok but no lines appear in the lookup panel I have created
nuke.LookupCurves_Knob.addCurve (n[‘ranges’], alowCurve[0])
nuke.LookupCurves_Knob.addCurve (n[‘ranges’], ahighCurve[0])

if then else in nodeLabel

i like to achieve something like this:

[if [value bypass] {"YES"} else {"NO"}]

the label of a node should show yes when the bypassKnob is 1 and no when it is else!

how do i have to format my yes and no string?

Breakdown Help In NUKE

Hello,

Within Shake, I usually use the "transition" node to do breakdowns and control frame duration.

NUKE’s switch node is all I could find to use to create some breakdowns, but confused about controling frame duration for a single frame (ex: making static image display for 2 sec @ 24fps)

Is there any other node’s inside NUKE to accomplish this?

Regards,

Changing the value of a specific node in a group through python?

Hi,

I’m having a little difficulty working out how to change the value of a specific node in a group through python.

Say I have Group1 with Blur1, Blur2, Blur3 in it. I only want to change the ‘size’ value of Blur2.

I’ve had a fiddle around but seem to have confused myself a bit (python newb). I haven’t come across any mention of this in the User Guide.

Any ideas?

Thank you

Can nuke warp footage with a displacement map(similar to AE effect)?

In AE I can use the displacement map effect under the distort menu and use my own B&W displacement map to create a cool effect. I can just use this effect in AE for this shot, but I would rather learn how to do it in Nuke and just tweak it in there because my comp is built there. It isn’t that much of a hassle to just do the effect in AE, on the tracked plates that I get out of Nuke. But, I just want to learn! What I am achieving in AE is the effect of warping from a plastic screen being in the foreground of a shot with a nodal pan. I am pretty new to Nuke by the way, so any help would be greatly appreciated. Thanks!

Tracking just Y axis movement

Is this possible? I am tracking a vertical nodal pan and there is no movement in the x axis, but because of warping on the entire plate from plastic screens in the foreground, I am getting choppy translations in the x axis. I am applying a clean plate to this shot and don’t have to worry too much about the y movement because i will be adding a displacement map to the tracked clean plate using AE. So, I just need some Y axis tracking with the x axis tracking being 0. Actually now that I think about it, I can probably just hand track the Y movement, but for my own general knowledge I would like to know if I can just obtain Y axis data from the tracker. Thanks ahead of time!
