Re: [Nuke-users] Removing light flicker
You can also try the curvetools IntensityData to compensate flicker when you use it in combination with a grade node. After tracking a flickering area with the curveTool, use the following expression in the grades whitepoint for every single color channel: CurveTool1.intensitydata and in the grades gain: CurveTool1.intensitydata(100) while 100 is the frame you want to stabilize to best, Falko Zitat von Gary Jaeger g...@corestudio.com: Magno- have you tried Re:Vision De:Flicker? http://www.revisionfx.com/products/deflicker/ On Apr 26, 2014, at 1:42 PM, Magno Borgo li...@borgo.tv wrote: Hi!

Re: [Nuke-users] layered projection on merged geo
Have you tried to increase the samples in the ScanlineRender node to
get rid of the artifacts?
Zitat von Michael Garrett michaeld...@gmail.com:
Actually, I'm still getting some minor artefacts using this method,
for whatever reason, with this particular geometryas opposed to
projecting across the merged geo. But once you add motion blur, it's
fine so I'll deal with it.

Thanks for the responses...Falko, your example seems to work, great! I
think it's counter intuitive to need to apply the MergeMat to each
separate piece of geo upstream of the MergeGeo or Scene node and I was
concerned there may be some artifacts doing it that way...but it works
which is what counts.

What about using an add channel node after your project3D shader,
shuffle into this newly added channel, then place an apply

but seems feasible)

I find this scenario extremely useful for adding touch-up projections

because the texture looks nasty at the overlapping area.
I'm not sure if I'm having a brain fog today or if this is something
that really hasn't come up for me before in Nuke, but the only way I
can see to do this right now is to have two ScanlineRender outputs. I
need something like a MergeMat but it's the MergeGeo (or Scene node)
upstream of it that kills the ability to use it. I figured this would
possibly be a good application of BlendMat but I can't get that
working except with the underlying vertex colour. Thanks for any

Use the first number(1) to select one of the three bracket pairs.
The second number(0) just deletes the last braket so no need to
change that. And the last one (2) selects the single values inside
each braket pairs.

Zitat von Nat Jencks natjencks.li...@gmail.com:
Hi, sorry for the relatively simple question, but I'm relatively
inexperienced with TCL and Python in nuke and this seems like it
should be very easy.
I have a text string defined as a userknob which I have called
CDL_TextValues. This contains a user enterable string which will
be in teh format of (1.1223 1.1881 1.2673)(0.1574 0.1245
0.0909)(2.0576 2.0576 2.0576) I just need to take these
individual numeric values and enter them into specific variables
which can be defintes as an expression, in my case, the
OCIOCDLTransform node.
I'd liek to use a range funciton to simply take the 2nd through
7th character and use that number.
So I'd like to set the expression for my value to be range
(CDL_TextValues 2 7). But I can't get it to work... seems liek the
native TCL commands dont support the range function, and I'm not
sure how to do this.
Thanks for any help!
best-

I have a photo of a leaf on a white bg. I'm trying to create an
alpha for just leaf. I have a feeling it's a real simple thing but I
can't figure it out.
I've tried the keyed node but I get nothing.
I want use the leaf on a card in 3d.
Thanks
