Animate Projection Geometrie

hi i need help with something.
i projected a plane(aircraft) on a card and deformed it.
now i want that the plane is moving on my groundplane….etc.
how can i animate the card or move it.because if i move it,
the card is moving but not my projection.I could do it in 2d before but is there a way to move it as 3d layer in my setup ? and how ? :confused:

thank you.

Roto help for a shot!

Hi All, http://youtu.be/7-yIskP6vE4
I am replacing the arched building to the left of this shot (Looking straight onto it at the end) and so far have tracked, modeled, textured ect ect, and I always thought ah once I get into Nuke I will just roto those bits out….then I took it into new and started to do a few little bits of roto, and releaised its probably not going to look great, especially the bars down at the front! Although Im thinking that if I moddelled them in 3D, I could then pull an alpha from that, for the gaps ect.(although any other sugestions gladly welcomed!)
But my big issue is the tree, how would you all go about that?

Thanks In Advance,

Keeping Read nodes from updating

I got a script with a bunch of read nodes, but am only using one read node in my script at a time, the rest are just standing by for when I need them. When I jump around on the timeline, they all light up yellow and load the current frame, even though there is no viewer connected to them.

Any way to keep them from doing that?

right view problem

I recently took a shot in simple stereo conversion
and i noticed that when i turn a keyer or merge
or anything with alpha into a 3d card my right
view is plain black though the left works fine.
Is that normal and if so how should i go
about to roto my shape in 3d?
( I try to have my character on a 3d card and
a cleanplate on another card).
Any advice will be appreciated.

Read colorspace affects depth channel?

Hi everyone.

Anyone knows if colorspace setting inside Read node affects depth channel values?

Thanks!

Particular bounce plane problem

Hi, I’m trying to setup particular particles to bounce off a plane but I can’t get them to bounce off it. I have set it up as close as I can to Steve Wright’s tutorial but it doesn’t seem to work. I also can’t find his files anywhere to use as reference so I can see where I’m going wrong..

I have an emitter with an axis node, a card as a floor (the floor transform fields under the ‘physics’ tab was greyed out weirdly enough until I switched random things on and off randomly btw), it’s really all very basic but doesn’t want to work.

Would be great if somone could help me out please.

Thanks!

P.S I just reloaded my setup and now the expression I managed to write into the ‘floor transform’ is gone and all the expressions are gone. The green link arrow were still there so I deleted the floor card and now I’m stuck not being able to write that in again. Is this a bug or error in user?

Photofilter in Nuke

Is there an easy way to do a photofilter like in After Effects/Photoshop in Nuke?

I haven’t been able to find a simple solution with decent results for this.

Roto/Rotopaint hotkeys

Hi,

I looked for it and could not find it here on the forum, but it is possible I am blind.
Is it possible to assign my own hotkeys to tools in Roto/Rotopaint nodes?
For example in Roto node Q is select tools, V is bezier drawing. I would like to add sth for "point operation" tools 😀

Cheers
