Hasta La Motion!

Nuke doesn’t seem to animate changing colours on the colour wheel, is there any other work around how to get it to change colour without having to do the whole grade again with a mix node..???!!!

Ok well I been having this problem in nuke, I have a green screen composite:

A over B

no worries.

but when I pop a transform in the A before I merge it over the B I get a black line wherever I move the transform to be. What can I do to fix this?

-I’ve set it to take metadata from B
-I’ve unclicked the ‘black outside’ in the transform box option

none of these seem to work… help!:confused::confused::eek::confused:

I hope someone has some answers now.

I’ve created a couple Gizmos in the past while that have had transforms nodes in them. I’ve given the user some control over certain things inside those transforms such as scale and rotation, but not translation. However when you export the Gizmo and even beforehand all the transform handles are visible on the viewer which I don’t want since I am using only one transform handle and don’t want to have the confusion of which one to use.

Does anyone know if this is a bug or what?!

I’ve gone through the manage knobs menu and made sure the only "transform matrix" (transform handle) available to the user is the one I want but I still get all the others. I’ve had this same problem with radials, crops, etc. but haven’t been concerned too much since the user wasn’t using any transform handle.

i have an conversion nk-script which writes scanline exrs in 16bit half.

the write-node is named "Write"

We also sometimes have channels like world position or depth.Z which we like to keep 32bit, so i introduced another writenode called "Write32"

I only want to execute this Write32 if channels e.g named "depth.Z" are present. I have no problem finding out if these channels are there, but my problem is to execute the additional node.

Nuke won’t let me execute another node via:
nuke.execute(‘Write32’,nuke.frame(),nuke.frame(),1 )
when its in batch mode…i get the message:
"I’m already executing something else"

Does anyone have a workaround for this?

I’m just finding my way around python scripting and cant get this simple problem solved. any help would be great.

I have made a group, and I am adding some custom control knobs and buttons to later create a distributed gizmo – pretty simple stuff.

I have made a user python script button (on the group) to create a couple of nodes (write nodes).

eg.
proxywriter = nuke.createNode("Write") proxywriter.knob("name").setValue("ProxyWriter")
etc. etc. etc

when i run the script from the script editor it works fine, but when i run it from a custom python button, it creates the node within the group – NOT in the main node graph.

how do i specify that the nodes are made in the main node graph, not the group the buttons are attached to?

Thanks in advance
