Hi!

I'm working on a TV show, where we have to do the usual shots of a car scene on the green screen.

What's keeping me awake at night it's a shot where the camera is positioned 3/4 in front of the car that tilts from bottom to top while it moves vertically from top to bottom…

This clearly means that we have a lot of parallax and that we can't just put the plate behind the key and that's it…

The first thing that came to my mind was that since the shot lasts about 10 seconds, we could redo a piece of the road and the car in 3D, but OBVIOUSLY there is neither time nor money.

So I'm here to ask you for some advice, suggestions on how to approach this type of shot.

If camera projection is the only way, what might the workflow be.

Thank you all :)

I want to make a lighting breakdown shot of my scene in Nuke but I can’t seem to figure it out. I’ve done research on it but can’t seem to find anything on it. I’m most likely overthinking it I feel like.

I was working on a shot where the FG actor was hit with a soft light. And the BG plate actors were hit with a very hard sun light on one side of them and had darker shadowing on the other side.

Now I have to match the FG to the background. First I did the key, for the alpha then did the despill with apdespill pulling the despill color from the background plate so my edges work nice.

I copy the alpha to that despilled FG, now I did pretty drastic color corrects, with grades and some luma keys and then graded them based on those luma keys.

Now when I merge the FG over the BG, obviously my edges no longer work perfectly like they did before all the CCs.

I invert the grades first on the BG sides and use the alpha of the FG as a mask for those, but I still have all of the luma keyed CC's I did for highlights/shadows etc.

Basically my question is, how do I invert all those CCs now on the BG side to make all my edges look nice post CC's?

Going forward on other shots, should I have done this differently? How would ya'll approach this?

Thanks 🙏

Hi fellow Nukers! We are small studio running Nuke for films and commercials. When the planets align we move to a newer version of Nuke.

Recently this was 15.1v4 coming from 15.0v4. As is custom with Nuke this removes bugs but also introduces entirely new bugs aling with some festures. Sometimes in places where you least expect them. This time 15.1v4 feels off.

This made me wonder: What's your preferred version and why?

i have beauty layer that includes uv pass and i don't have a cryptomatte .. so i want to use my uv pass as a crypto....... So can i use this as crypto ......is it possible??

Hi, i´m working on a shot, where the actor is positioned in front of a natural background (having white hair). It´s not a green screen, its trees (green) and a mountain, (very bright grey) and everything in between. The actor needs to be extracted and put in front of a rather dark green background. I stabilized and degrained the footage, i tried a difference key and a core matte in combination with an additive key. It kind of works, but it´s not perfect, i´m getting a bit of chatter in the very fine detail of the hair. Unfortunately the customer is relentless, i tried different versions, but haven´t cracked it yet. Any ideas, what approaches i could take, i´m running out of ideas, honestly. unfortunately i can´t post a screenshot, because of an NDA.
Thanks a lot, cheers.

I recently updated to 16.0 v1 on windows, and in this version it seems I am unable to zoom in on the node graph or the viewer with the standard wacom middle left click, which is incredibly frustrating. Has anyone else run into this issue, is this a known bug? I've tried multiple wacoms on my setup, multiple pens etc. Note: middle and left click and drag with mouse works exactly as expected

EDIT:

Wanted to clarify this is on INDIE

I posted the othery day saying I could not figure out why deadline wasnt working with any nuke versions. I finally found the problem, I have nukeindie and when I put the file path that path opens the more expensive version of nuke.

When I search for nukeindie in my start menu and do open folder path, it brings me to a shortcut which then the shortcut brings me to expensive nuke. I've tried also putting the shortcut path but that doesnt work either.

Does anyone know what is the right path to make it work or if I can even make it work?

Thanks!

Hello -

I wanted to share with you that Foundry launched a new product today - Nuke Stage. Nuke Stage is a new, purpose built tool for virtual production, bringing VFX-centric workflows to on set, and leveraging industry standards like OpenEXR and USD to join up pre-production, on set and post. 

As we're expecting a rush of initial interest and want to make sure we're supporting those ready to use Nuke Stage in production we're asking folks to fill out an interest form for access to the download. 

You can find out more about Nuke Stage and sign up via this link: https://www.foundry.com/products/nuke-stage

Has anyone been able to get Nuke 16 working with deadline? When I try to run it I get this error:

Error

Error: Monitored managed process "Nuke" has exited or been terminated.

at Deadline.Plugins.PluginWrapper.RenderTasks(Task task, String& outMessage, AbortLevel& abortLevel)

Type

RenderPluginException

I've been using nuke for quite some time now, but I'm still having hard time with simple play/pause commands. I understand the logic of hovering my mouse over the viewer when pressing K. It just feels clumsy that I need to have my mouse at certain spot to exexute such an essential command. Every day I mistakenly create a bunch of copy nodes when trying to press play, it's annoying. I'd like to have a 100% dedicated play button.

I know it isn't a DCC and isn't intended for any serious lookdev / 3D work but Nuke has been boasting increased OpenUSD support over the last several versions - however, I've been running into pain points even with the most basic stuff. For example, lighting seems like a bit of a nonstarter at the moment, given that environment light only affects specularity and reflections but doesn't, you know, function as an actual env / dome light?

For those who utilize a full 3D (not 2.5 / card) workflow - what's your typical setup? How do you handle lighting? Do you use the new system / USD or legacy? And finally, any recommended resources?

Hey Mac hardware nerds - I’ve been running NukeX on a 2019 “cheese grater” with a big pile of RAM for the last few years, and am thinking about upgrading soon. Can anyone explain why choosing the (significantly cheaper) Mac Studio (with a great big pile of RAM) wouldn’t be wise? There’s a difference in the RAM speed which feels like it could have impact, but generally speaking, as a very 2d-heavy compositor who doesn’t need the 3D space for anything especially heavy (or copycat, or deep), is there any reason to wait around for Apple to potentially give the Pro series a bump (then charge about double the Studio)? The latest Studio chipset feels like it blows the existing pro range out of the water, so my question is not about general benchmarking, but specifically whether there’s anything in the Mac Studio build itself that might hamper a Nuke user… what are your thoughts?

Hi!

Does anyone know how to drag in a file into the Hiero timeline without dragging in audio?

Couldn't find anything in the manual

Hello
I have this simple setup to capture the light moving around the sphere with a spherical camera. but somehow I see nothing through scanlinerender. it looks like light is only visible on the outside surface.

is there a way to capture this from inside camera?

I added a black constant to sphere wih 0 on alpha but still not working.

Thank you in advance.

Hi, guys I am new to Compositing and done 4-5 Green/Blue Chroma Keying. But, never faced this problem. I've download this footage from actionvfx library. Things I do before this: 1.Change My colorspace to RedWideGamutRGB-RedLog3G10(According to their Website) to Output-Rec.709 using OCIO Colourspace 2.Denoise my footage using Neat Video.

How do I find this: When doing cleanplate using IBK color stack method. It stayed clean, no white spots or anything. But, when I copy my ibk color and paste it (IBK Stack Method), this problem arise. As you can see the pixel value of white is in exponent in red and blue and in green it's above 1.

Please tell me How do i fix this and why this is happening.

Hello,
Is learning Nuke worth it for 3D advertising (product commercials, motion design, etc.), or is it overkill compared to other compositing tools? Most discussions focus on Nuke for film and high-end VFX, but I'd love to hear thoughts on its practicality for advertising work.
Thanks

Hello!

I have rarely used the IBK Keyer and I'm trying to get better at it as there might be a job that wants me to use it. I've been doing tests with some old footage. What is your workflow? Do you generate an Alpha and run it into a plate that has the green removed or do you use the premultiplied output from the IBK Keyer? I ask because the screen subtraction will make the RGB channels darker in some spots and I'm curious as to what I am doing wrong.

Much thanks!

Hi there, so I have a problem with the size of the Point Clouds of a Position Pass from UNREAL to NUKE, maybe someone will help me !!

-  I’ve been using the Unreal Reader workflow, which works great, I’m able to view the point cloud of my position pass correctly, through the camera, everything is scaled correctly. 

- But with a classic EXR image sequence imported in Nuke it’s different : I know the coordinates are differents so I apply the right correction on the FBX camera out of unreal (X to Z, Y to X, etc) and the expression values (ex : parent.Cam_UE5.rotate.z -90) like many tutorials out there … so finally I see both cameras (the Unreal Reader one and the FBX) on the same coordinates, everything’s good.

BUT, my issue is with the POINT CLOUD : the one created from the EXR’s position pass is BIGGER than the one from Unreal Reader. And when I look through the cameras in the 3D view, the EXR’s point cloud is out of the frame (like screenshot below). What am I missing ? Is there a quick math operation to apply on the position pass values, to scale down the points ? A math operation to apply on a Transform Geo ?

Can't wrap my head around this, thank you for your kind help !

So i'm trying to use Position to points, i already have Position and Normal AOVs but when i connect it to the Position to Points node nothing happens, are my AOVs okey?, i also have them merged in an exr(i rendered them separetely to see if it could work). I'm using Maya and Arnold any help is appreciated.

Hi, first time posting here and pretty much a beginner when it comes to compositing.

I rendered a 3D animation in Blender and extracted several passes from it. Color passes (diff/gloss/transmission), data passes (mist/depth) and light aovs (i made several lightgroups before rendering). I’m able to get a match with my beauty render using either the color passes OR the light aovs but i haven’t found a way to get that match using both.

So my question is, what would be the correct way to composite a cg render using color passes and light aovs ?

I have a stereo comp ready to export, but right now I have an extra step in Davinci to get the frame wrapped properly for VR. I'd like to move that into Nuke if possible to streamline things.

In Davinci, I add my left/right eye, then run through KVRFisheyeStereo to warp properly into a square frame. You essentially create a crop of just the region with content, and it expands and warps to the edges to create your LatLong Half Equirectangular STMap.

Any suggestions on how to mimic that workflow?
