Hasta La Motion!

Just throwin’ this question out there. Its not too important, more of a convenience than anything else…

I’m just curious if Nuke has an option to color a mask or matte with a specific color, so you can tell different mattes apart when you turn off your overlays.

Or should I just stop being lazy and just combine a constant color into a matte?

Oh, and I just thought of this while typing…

If I want to recreate a breakdown from a shot, and I wanted to do a quick pass to show the alpha channel of a greenscreen comp, how can I get a shot of just the black and white matte? I’ve tried selecting alpha, and rendering out in alpha, but instead i’ll get a red coloring, or other weird colors. How do you guys usually do breakdowns like this using nuke?

Hmmm this has been boggling me all day…
I’ve got a pan and tile setup (see link)

One of the artists here wants to do some Photoshop work on it but there are like 20 images which is a pain for them to edit invividually… so is there a way to "Unfold" the pan and tile setup and save it as one image, that I will then be able to map onto something else later?

Thanks 🙂

Hi all,

I’m currently working on a gizmo that includes a GodRays node. What i want to do is have it so that the "center" parameter in my GodRays node is always in the middle of whatever footage you have piped into it.

So i was hoping there is some form of expression that can find the vertical and horizontal size of the source and then divide them by 2 to find the center automatically.

thanks in advance

I have successfully installed dcraw via terminal in OS X http://dcraw.darwinports.com/
Now after attempting to place in a read node, Nuke is telling to me to make sure that my dcraw install is "In my Path"

1. What does that mean?
2. How do I do that?
3. Once this is solved are there any tips on how to implement dcraw to it full functionality via nuke or is that automatically taken care of by Nuke.

I have run a "man" command in terminal and it came up, but I wasn’t able to glean the info I needed to solve this

Hello everyone. I am doing comps where there is media as DPX_NAME.10029.dpx through DPX_NAME.14029.dpx and stuff that is DPX_NAME.TIMECODE.DPX.

Nuke wants to only put those clips on the timeline at the DPX sequences timecode? How can I push these clips so even though their fame number or timecode is a certain sequence say 15000-150100. They are at my timelines frame 1-100?? If I change the "frame range" on the read node, to say 1 – 100 it says the frames aren’t there, because it thinks the clip wants to start on frame 15000.

How do I do this?? In SHAKE we had an in and out range, even if the frame number or timecode didn’t correlate to that..

Thanks.
