Hi there,
I'm kinda stuck with a script, and though I think its probably an easy fix, I
haven't found the solution yet.
A very simplified version of what I want:
- grab the 3d position of a selected vertex,
- print this value
- move to the next frame and repeat.
The script I came up with :
import nukescripts.snap3d
for i in range (0,100):
nuke.frame(i)
vertex = nukescripts.snap3d.getSelection()
for v in vertex:
vertexXpos = v.position[0]
print vertexXpos
The problem is that, when executed in a loop, the vertexposition is identical
for every frame (it always uses the values of the first frame). If I remove the
forloop and just execute the script manually on every frame it works as it
should.
My guess would be that I have to force the 3dviewer to refresh on every frame
so it updates the vertexpostion. Am I right, and if yes how can I achieve this.
Thanks!
