link transforms with gridwarp cvs

Posted in: NUKE from The Foundry
hi i am working on a shot in which i need to attach transforms to gridwarp cvs. it all works well, the problem is that nuke seems to ignore the interpolation method of the keyframes in the transform nodes. it basically only interpolates linearly but that is very bad because i need the interpolation to be exactly like in the transform node. is there a workaround or is this a bug already filed?

i’m working on a beta (5.1v3b2) and cant change the version at the moment…

greets and thanks in advance!

fbx help

Posted in: NUKE from The Foundry
I’m trying to import some fbx data into nuke.
When the 3D guys open the fbx in maya, everything lines up (cameras and objects), but when i load in the fbx into the camera and readgeo node in Nuke, the camera is too far back.
Needless to say i’m pretty new at this, but can someone walk me through the steps?
I’ve tried the things in the manual, but that leads to the camera not being in the right position.

Also, does nuke measure hapature and vapature differently to maya? (mm vs. inches?)
Thanks so much for the help.

Stabilizing issues…

Posted in: NUKE from The Foundry
Hello VFXtalk Community,

I’m having a bit of trouble properly stabilizing a steadycam shot:

The shot contains a closed bathroom door filmed from the outside, with only the door itself in the picture as well as a huge lamp next to the door.

Now, I had to speed up the middle part of this sequence to shorten it a bit (I needed to
"take out" 592 frames without anyone noticing; if there’s a better solution to this – I’ve
tried some, but they didn’t really work out well – please let me know 🙂

What I intend to do now is to absolutely stabilize this shot, then filtering the tracking
data in the curve editor to simply give back some subtle shakiness.

I’m a novice to Nuke (but love it already 😉 so please excuse if my following problem is
too trivial..

Well, I got three points within the image which are suited for tracking; the doorknob on
the left, and two lamp features on the right. When I track all these and hit "stabilize",
the image tends to "morph" in order to stay in one fixed place. I guess that’s because of
the subtle perspective change due to the original shake, so it makes sense. But this knowledge doesn’t help me at all 😮
Using just one tracking point doesn’t help either due to the source’s rotation.

Could someone please give me a hint where my thinking lacks? Any help would be appreciated 🙂

Thanks a bunch in advance!

gamma exr

Posted in: NUKE from The Foundry
Hi everybody! I’m new in VFXtalk and new in comping too.

I was reading many of the post talking about gamma and exr files, and I got a doubt:

Somebody says that rendering in 2.2 gamma in exr files is bad bad bad. Some replies later, somebody else says that, If you don’t get the desired result you can put a grade and that’s all. (that was I was doing, till now)

Is it incorrect? Is it affecting the final result?

I didn’t try it yet, but I think I would reach the same result (moreless) without rendering in gamma and play with the shadows and occlusion pass… …
Would it be better?

Thank to all help.
