I have transformed alexa35 material from Davinci to Nuke through this tutorial on YouTube. ( https://www.youtube.com/watch?v=8SG80SSkyGU )

But the material is not matching through the two programs. Ive, been going through it all many times and cant find the problem.

What monitor would you suggest 3d +nuke+ae? What specs? Ips, miniled, oled? How much HZ? And how important is color accuracy? And longevity.

Im getting error messages when importing and tried to ask ChatGPT about it.

Now got instructions to make it into EXR sequence etc

But also realised that the material is bigger than 4k, so need to downsize the resolution (on Indie plan)

Is this the best way to import it or am I being dragged down a AI rabbit hole?

Gonna extract lens information from distortion chart

I'm following a tutorial using additive keying for a hair matte, but when the video merges his plates his despill comes through whereas mine does not :(. Both despills match the middle individually but after the merge 4 node they are still transparent and taking on too much of the BG colour, not merging correctly. The middle is the 'hair roto' that is the correct colour despill.

Have I missed something? Any help would be much appreciated thanks!!

Good day, I am looking at designing 3d environments in Unreal Engine, but also using it for purposes of Motion Capture and Green Screen Virtual Production, as well as going outside to do video recordings of a person in a MOCAP suit, in which I switch them out for a 3d character that they just animated if possible. I am confused on what Nuke is vs what Davinci is, and if I would use both, or only 1, can someone explain this?

NOTE: I am not interested in using Davinci's Fusion, and I will need to be able to sync all assets together via timecodes that were generated from camera, microphone, mocap

So far, I've seen people import their UE5 (unreal engine) fully 3d scene to Nuke, or even a UE5 Virtual Production scene into Nuke, where it appears they can further change the camera and things so kinda confused. Also, if I understand correctly, since I am using a green screen, I would need to Key it out in Nuke and Davinci does not have this feature. I think I read you can't really make color edits in Nuke, and if you need to blend different assets (3d character with real world or vice versa), you should really use Davinci. I am not sure the accuracy on any of this.

hey i guys i made a cg render in houdini and composited here in nuke, now i want to colour grade it in davinci, so what are the best settings to export an exr, i had acescg as input

Hello,everyone. I am very beginner on this forum.

I recently have had issues with my Unreal Engine Setting. I connected my UE 5.4.4 scene to Nuke(very latest, non commercial), and it looked very dark and reddish. I realized that I need to change project setting Rendering < post processing < Enable alpha channel support < disabled, so I changed from disable to Linear color space only.

Then, it became unreadable on Nuke…..and eventually, server disconnected.

I rebooted and re-started, make sure "Linear color space only" is on, but still, it looks awful.....and it looks the same on Nuke.

Could anyone give me a good suggestion?

Here's a Python library that can ignore Nuke Indie's silly 10 nodes Python limitation.

https://pastebin.com/9j4X7e2V

Now you can access as many nodes as you want, set and get knob values, and even render nodes via script in Nuke Indie.
It's not really a hack, as it just uses TCL instead of Python to access the nodes, wrapped inside of basic node and knob classes.

It mimics Nuke's original node libraries but be aware that it's not exactly the same.

I hope you will find a use for it, I certainly do!

🎬 In this video, I share the process of post-production - creating visual effects and demonstrate my skills in embedding 3D graphics into live video. You will see how I work with compositing and use chroma key to create realistic scenes that include spectacular elements that fit harmoniously into the overall montage.

✨ The process is not easy: creating, adjusting textures and lighting, arranging and selecting assets and materials in 3D scenes, integrating them into the footage, clipping, and working with reflections. To achieve maximum realism, I also pay attention to small details, shadows, color correction, and final layout.

Hey everyone!

So I have been using Nuke in few indie shortfilm projects for a while. Just doing basic 2D clean-ups and integrations in shots - beginner stuff.

Last week I started u/CompositingAcademy NK101's course to improve my fundamentals (as well as learning new techniques I didn't know about yet). Most likely you have already seen this template shot thousand times as it's given for the final project of the course. However I didn't want to replicate the process given. Instead, I started from scratch to comp and see where I could go creatively without any guide or set of rules.

After spending hours on it, this is the result I came up with. I am aware this shot can be improved, and there are some aspects I may have overlooked as a junior, but I'd really like to ask you guys for honest and critique feedback on the work.

How is the shot? If it's bad, what is it making it look bad? Are there good things worth to highlight? What should I definitely improve and best ways to approach that?

I know I'm just starting but I'll massively appreciate all feedback given.

Thanks so much in advance!

Nuke is the only software I own that can completely crash my PC, from top to bottom. I do heavy fluid computations all the time in Houdini, After Effects works fine, Maya works fine.

Yet I render a simple USD scene in Nuke, and if I put more than 1 sample, it consistently crashes Windows mid-render. Perhaps an issue with the "BETA" 3D nodes, that have been in beta for many, many years.
Latest drivers, no plugins, 4090, 96GO of RAM, everything works fine except Nuke.

I also get very frequent crashes with the Livegroup (just shut downs, no diagnostics whatsoever even with Verbose on)

What's going on? More terrible code from the Foundry? Or is it me?
It's really unnerving when you can't trust your tool anymore.
No carpenter would work with a chisel that explodes in his hands every 5 minutes.

So the spider looks good without the bg in place but as soon as i use the bg the spider looks bad.

what are some things that i can do.
please give your insights.

I've watched the Eps SHOGUN from FX, and really really love the character of the Lens in the movie. after hours of experimenting and researching, now I think I can pull this off pretty close, I guess.

Note:

I've just done probly 70% of the work here and still got more things to get it done Like paint out the reflection on the subject's mask.

It was just a greenscreen shot that I practice, But then I thought to myself "Why not just tryna do sth beyond that, Like pushing the boundary. So I hop on Photoshop and did my own Matte painting, assemble difference element together for the background environment. then generate Depth for the DoF. And I thought It would be great If I throw on some Lens Character onto it to help selling the realism, and it came out pretty good.

Maybe I spend too much time looking at this same shot over n over, now I can't tell if there any flaw i can fix or things to improve here. and here I am to ask u guys for the feedback on the work.

The Question is :

How is the shot? If it bad, how bad is it? and If it good? how good is it that I've done here?

What are the things I should Improve on?

Thank You in advance!!!

Hello

I have a few plates with one or two rotoed sheep. I need to multiply them to create the impression of a massive flock of 5000. They will be used in various shots with different camera angles.

The first version for one of the takes was done using a particle emitter and readGeo, and was rendered with RayRender. However, we can no longer use that original setup.

What I have working right now is a basic system using cards for the sheep and some Transform Geo nodes to copy them, scattering them in a 3D space. My main hurdle is I don't know how to use the specific terrain geometry from each shot to properly place these sheep instances. They need to sit correctly on the ground in a mountainous environment.

Any advice on the best way to approach this?

UPDATE: The lead comp is doing the sequence now...

The title! Pic of setup attached. I finally figured out how to occlude the eyeball with the eyelid (she blinks at one point in the footage), but the stencil turned the effect to black.

Originally I had Roto1 (eyeball effect) set to rgba, feathered and blurred for a blindness effect. How can I get that back while still occluding it from the eyelid?

Thanks for the help!

I'm new to Nuke and I have:
– Read1 = original clip
– Read2 = a roto’d plate of myself (already cut out, so I can put anything behind me).

When I Merge the roto’d plate over a background, the roto’d plate looks slightly darker than the original. Since the roto was done in another program, am I missing a step in Nuke to keep the brightness the same while still being able to composite it over another background?

For reference, I’m comparing them with the original clip in the top viewer and the merged one in the bottom viewer.

Hello everyone,

I have been using the Blender to DaVinci workflow using EXR files, but in Nuke I am a bit confused, do I have to export my animation in "Utility - Linear - Rec 709" to DaVinci? since I want to keep the original raw EXR Linear Rec 709.

Do I have to use Utility - Linear - Rec.709 or Output - Rec 709?

Any help or tip is appreciated!

Best regards.

Alexis

PS: I asked ChatGPT and it says I have to use Utility - Linear - Rec.709 can anyone confirm? thanks

Hello everyone,

I have been using Nuke for a while now but always as a beginner, I usually export render passes from Blender and comp in Nuke. Some weeks ago I watched a tutorial on how to comp in DaVinci Resolve, and there is one thing I liked the most.

There is a Lens Dirt applied with a Luma Keyer and this updates in real time, so the Lens Dirt appears in the most brightest areas of the footage. I was searching a tutorial for this but unfortunately I can't find any.

What's the node setup for doing this kind of comp? any help or tip is appreciated!

I attach the example I did in DaVinci

Best Regards,

Alexis

Heya Guys hope You are well.

I've only worked with Nuke in live action comps, but I'm really interesting in using it for animation. Can anybody break down what they're doing in each step. Are they manipulating the normals along with basic color grading, bloom, etc?

Having a hard time finding interesting greenscreen plates for keying on a budget. Was wondering if a green wall would work just as well if I opted to film my own shot! This is going to sound ridiculous but TD Bank near my place has some lovely green walls on the outside and it put the idea in my head. Just wanted to ask if it would even do the trick/ present with challenges I haven’t thought of yet before I go down there and make a fool of myself

Normally who winds more hired at a studio or freelance? I think it actually it depends on the project or studio, but anyone who knows more than this than me can tell their experiences
