Dpx RGB + A Render

Posted in: NUKE from The Foundry
Hey everyone,

I tried to render a dpx sequence including a alpha channel. After i did it, I load this sequence into nuke and everything looks great.
But when we load it into After Effects or Flame it appears total wrong (see the screenshot)

When i turn off the Alpha in Nuke’s write node everything works great, in Afx as well as in Flame.
Does someone know why this happens or is there something wrong with my write node???

Thanks in advance!

EXR renders from Maya 2009 error on and off in Nuke

Posted in: NUKE from The Foundry
For some reason some of my exrs out of a batch will error "unexpected tile x coordinate" this is sporadic through one particular render. The file size is exactly like the others is there a way to fix the error?

when I view them they have no visual content… no alpha nothing but haven a file size around 8mb. tried opening with other software have same issue. It has been happening to allot of my renders recently…any ideas?
Thanks !

nuke python + get node in focus (runIn)

Posted in: NUKE from The Foundry
hey ppl.

I’m having a hard time identifying a node within the current focus.

this is quiet a good solution for getting the nodes.. what annoys me is the result.

Code:

for group in nuke.selectedNodes():    currSel = nuke.runIn( group.name(), 'nuke.selectedNodes()')
    print currSel

which returns

Quote:

# Result: [<RotoPaint5 at 0x0000000004E96EB0>, <RotoPaint3 at 0x0000000004E8C130>, <RotoPaint4 at 0x0000000004E96E90>]

is there any way to filter this results to get a clean name array like:

Quote:

# Result: [<RotoPaint5>, <RotoPaint3>, <RotoPaint4>]

thanks for help!

Missing “N” Channel from geometry?

Posted in: NUKE from The Foundry
Hi all,

I recently upgraded to Nuke 6.1, but now a script created with Nuke 6, I gives me an error for the UVProject node: "UVProject: Missing ‘N’ Channel from geometry". Does anybody know how to resolve this? Does it have something to do with the obj. files I use to project on?

Thanks in advance!

Displaying ObjectIDs

Posted in: NUKE from The Foundry
I have a channel with ID’s in it (integers, 0-255)
I would like to display that on screen with different colors assigned per ID.
(i.e. not just a scaling or simple ramp)

Simple 8-bit style LUT?
Is there a simple 8-bit LUT type mode where I can pass this 255 value into and receive RGB values out, like a palette system from years ago.
Are there built in hue expressions so I could calculate RGB from HSV from an expression? (or is that only available in Python?)

Thanks.

Breaking Roto’s

Posted in: NUKE from The Foundry
I have a nuke issue that I’m hoping others will have some suggestions or experience with. I have done a large amount of roto on a shot and left it for a while. I needed to do a last change but found upon loading it up that nearly all of my roto shapes have had all of their base positions shifted. My shapes still animate as before but where once I was rotoing a head it might now be shifted to the thigh. This is the case for nearly every roto shape. (For Flame guys) Picture someone doing an axis with a single point repo or a translate keys.
I have had this happen right after I started a roto shape in the past but never after full completion. In those cases I just manually corrected the position on the few key frames I had. It seems to be off in all versions of my saves. I’m working on a new computer with a new version of nuke so that complicates things though it shouldn’t make a difference since I have had the "lite" version of this glitch before.

Has anyone else experienced this?

Thanks for the help!
