Help! Camera projection is not working right, actually Im not working right.

Posted in: NUKE from The Foundry
Camera 1 is the boujou camera imported.

Camera 3 is the girl’s camera for her 3D projection.

All layers in the scene project fine, such as for the fence and floor cards, and follow the camera as it should.

However the girls layer (card), is being projected by camera 1 and is distorting the angle as the camera tilts up at the end of the shot.

View the attached for details, how can I line it up so the girls layer follows the boujou camera, I dont really understand whats going on here.

In After Effects, I would auto orient the girls layer towards the camera, what do I do here?

Thanks.

Node not updated on first frame

Posted in: NUKE from The Foundry
Hey Guys,

Is there a way to force a node to be (re)evaluated? I’m having some trouble getting the first frame of a batch to render correctly, yet each subsequent frame works fine.

We have a custom node on which setting one value changes another. After wrapping it in a gizmo and exposing both values it all seems fine until it goes to render and the result isn’t coming back until the frame changes. (Or at least that’s as far as I can figure out). Just wondered if anyone here had seen anything similar.

Cheers
Ian

Take a snapshot with nuke? anyone?

Posted in: NUKE from The Foundry
Hi All,
There was a 3rd party script that goes into After effects, and it allowed you to simply grab a single frame onto your clipboard. From there you could paste it into photoshop, etc..

Does anyone know if there is a gizmo, plugin, etc, that can do the same in Nuke?

So many times I need a single frame from a sequence, and have to "render" it out.
I was hoping for a 1 click wonder.:D
Thanks,
Lou

nuke python weird

Posted in: NUKE from The Foundry
python syntax in nuke.. I don’t get it at all.

I’m just trying to deactivate postage stamps fo certain selected nodes.
but I have no clue how it works and sadly python is completely different from maya.
I can’t even get one command to work :veryfunny

Code:

import nuke  sel = nuke.selectSimilar(nuke.MATCH_CLASS)
  for i in sel:
    nuke.setValue('postageStamp', '0')

thanks for input

Alpha Blend

Posted in: NUKE from The Foundry
Hey, I’m working on a shot where I need to do a roto on some trees. I managed to pull a decent key on the tree, but the edging wasn’t what I wanted to I had to go in and hand roto it. The problem I have is that I’m getting a hard edge when I’m blending the two. How can I get the edge of the roto to soften, but only where it is overlaying the other alpha?
