Thanx
I’d like to render a Half-sized or smaller vers. of my composite to test before my final Big render.
-lowering the quality of the render doesn’t work
-reformating the composite to a smaller size doesn’t seem to work either
any help would be highly appreciated.
P.S. I do understand basic difference between spaces, and why LOG is behaving different in linear Nuke, i am interested in cases when it is better than just lin. 😉
Sorry if this is a stupid question. I’ve done a few things in Nuke’s 3D system out of necessity, but this is the first time I’ve tried testing it thoroughly
Sounds dead simple but can’t manage to make keyframes work on an expression linked knob.
Just made a quick example to shows what i mean.
If i move my "2d position knob", set keys on the expressionned knob "blackpoint" after moving it. It doesn’t works.
Of course i can animate my "2d position knob" but that doesn’t fit my needs.
Is anybody has an hint about this ?

It’s connecting the top of the model in a very strange way? I’ve posted 2 screen shot from Nuke. One with the poly’s showing and the other without to see the anomaly (it’s the white triangular area) more clearly. Can Nuke actually edit the geometry?
Thank you so much for any help.
How can I do for subtract a mask from another inside one node of rotopaint?
( I’m thinking in the some way of mask of aftereffects)
thanks!
The simple question is how do I export this from Nuke while maintaining the alpha channel?
I want to do this directly, in other words I have nothing else plugged into it, just want to render it out with alpha as a test.
It’s to then be opened in FCP, and I’m using Apple ProRes 4444 which is supposed to support alpha channels. I have tried PNG too which is the format the clip is originally in and that hasn’t been a success either. In FCP I make sure to change clip to ‘straight alpha’ in ‘item properties>format’.
^Despite this, I have no alpha channel after the render from Nuke.
I’ve tried many different settings of ‘premultiplied’/’auto alpha’ etc. and I get no joy.
I know/think it’s going to be something simple, but I just can’t see it!
If this test works, then I am hoping to key some footage with Primatte and export the footage with alpha for compositing in FCP, so this was meant to be a ‘simple’ test. Is it possible to do that – remove green screen and export the footage with alpha channel for direct overlaying in FCP?
Thanks for any help.
