Bug related to keylight node is not fix.

Now it is probably safer to use the Keylight GPU (if we can call it that) the Chromakeyer node. Doing so should not lead to the errors that usually come randomly from the Keylight. I hope it helps.

HI there When you are using keylight you're pulling a ok key but you need a garbage mask to preserve the plants.

There is a bug in Keylight which causes Nuke to crash when scrubbing the timeline. (fast scrubbing) It only happens when a rotoshape, or another keylight, is plugged into the In/OutM. Heads up if you're using Nuke10.x.x

They just released 12.2v3, which should fix the keylight error

*edit: links to the bug tracker https://support.foundry.com/hc/en-us/articles/4404797861266-ID-450001-Unsupported-Matte-tidy-mode-mode-appear-in-Terminal-using-Keylight https://support.foundry.com/hc/en-us/articles/360019443179-ID-449538-An-error-is-output-to-the-console-when-adjusting-Screen-Matte-settings-of-the-Keylight-node

Use a incident gradient affecting a driver or as a layer mask, and subtract or had that value on a rig in reference to that keylight to reveal/hide the scratches. You just need the angle from the keylight to the camera... That should do the job.

heres my reply in a reddit thread If anyones from the future, you set the roto to an OutsideMask component in a keylight (the OutM arrow coming off it), and set the 'OutM Component' in the keylight to Alpha, the it will cut out whatever you bezier in

Anyone seeing this on nuke 7.0v6 when launching keylight? Constructor for OFXuk.co.thefoundry.keylight.keylight_v201 failed Cheers Howard

While working today a Keylight node in my worklflow suddenly corrupted? I was not editing the Keylight node, but working on a Kronos node upstream from that node. error is: Keylight: 'OFXuk.co.thefoundry.keylight.keylight_v201': unknown command.

But I still can't load the Keylight node... I'm using Nuke12.0v2 on mac os Catalina.

keylight node in previous projects.

Send a screen shot of Keylight with the watermark and also, go to Help, About Nuke and send a screenshot of the splash screen. Thanks Lenny

Edit: Upgrading to 12.2v2 fixed the issue but now keylight is throwing a license error, nice :( Hi guys, For some reason in Nuke 12.2v1 dragging any keylight slider makes nuke freeze and crash on my computer.

Se this thread, problem is related to despot and erode knobs in Keylight: https://community.foundry.com/discuss/topic/155592/unsupported-matte-tidy-mode

Starting from empty script and calling keylight node will bring that same error and when I want to close Nuke, it will crash. I have also Nuke 10 beta installed and on that version Keylight loads OK. Nuke 9.0v8 is not working.

Hi Tim You can find the example on the following page, it's called Tutorial asset 3 - MerlinBlue : http://www.thefoundry.co.uk/support/user-guides/#keylight Direct link to image download : http://thefoundry.s3.amazonaws.com/products/keylight/assets/MerlinBlue.tgz

If keylight does what I need then I'll be happy. :D

Then, create a basic keylight without any adjustments, connect its source into the second footage and the outm on the new keylight to the new rotoscope. Create a merge, set the A pipe to the new keylight, and the B pipe to the old keylight.

"chromakeyer" is basically a GPU keylight if I'm not mistaken. As a workaround for now, if that works for you as a temporary solution.

First noticed it in 12.2v2 and was excited when the 12.2v3 release mentioned a fix for this exact Keylight bug, and yet...

I have never seen this but I hardly ever use Keylight these days. Have you tried clearing your ofx cache? I.e. the 'ofxplugincache' file/folder in yout temp directory

I installed the Beta Versions before, and when I "upgraded" to the non-beta, the watermarks on Keylight are still there.
