How are you intending to filter?

Create card, Scanlinerender with your camera. Normal 3D setup. Right after

The deep will be matched to your Maya renders.
Let me know if you have questions.

Use Nuke's Scene node to set the display to 'off' or Atomkraft's
'AtomReadAsset' node that can load in the geo as points or bounding boxes for
viewport display and then render them fully at rendertime. Simply export the
instanced spheres as Alembic format and read them back in.

As the camera is jittering so much you may have to use 2d trackers or manual
tracking and use 'User Tracks' in the Camera Tracker, Tracking tab.
There also may not be enough parallax to do a 3d camera solve

Hey, Ive just rendered out all my layers in maya such as the ligths, diffuse,
specular etc etc, but when I try and bring them into nuke I have to make a read
file for each individual pass because for some reason it wont import a single
EXR sequence with layers.
How do I get around this :S?
Yes - just put the image on a 'card' - paste the text below into the your node
graph to see an example.
set cut_paste_input [stack 0]
version 7.0 v6
CheckerBoard2 {
inputs 0
name CheckerBoard1
selected true
xpos -264
ypos -196
}
Card2 {
control_points {3 3 3 6
1 {-0.5 -0.5 0} 0
It sounds like the passes from Maya we not rendered as a multi-channel EXR and
that the layers themselves have been rendered as separate image sequences

Also, where abouts is the setting in V-ray (maya) to convert the render to a

2. If you turn on 'black outside' on the transform, you won't get the

Your problem is caused by incompatible formats (e.g. HD vs . Cinemascope)
The great thing about Nuke is that it will accept any format at all. The
downside is that this can cause workflow issues.
Crop, Reformat, BlackOutside can all help.

I think he meant :S as in 'confused face'.
When you say rendered in 'layers' do you mean separate exr sequences per
pass? How were you expecting Nuke to bring them in? Each pass in a
separate channel? You either need to render into a single EXR from Maya
or bring in the passes individually
What I gather from your post is that you have rendered to multiple EXR's
instead of one EXR with layers. This is actually my prefered way of doing
it as a multichannel EXR requires you to shuffle out the layers anyway
(unless you want to specify what layers to merge in every merge node eg.)

Thanks for checking in! It occurred to me that if you had a bunch of

I have never had any issues with cloning nodes corrupting scripts, but if

Don’t forget that multi-layer EXRs have higher read overhead than single-layer
files do, since layers are scanline-interleaved within the EXR file itself.
Until everyone starts using EXR 2.0 (including Nuke’s exrReader), separate
sequences is still the more efficient option.
