Sounds like the OFX version uses normalized pixel position instead of
absolute ones.
You would need to to divide your image resolution by the tracked position
to get the normalized coordinates

Re: [Nuke-users] 2d tracks or x y data in nuke used with Particular

2016-09-21 Thread adam jones 

Hey hey

What I am getting at is that say I have track a point from x 100 to x 600 and y 
35 to y 450 in nuke

then I take this data to AE and plug it in to particulars emtier x and y all 
tracks fine

but should I take the same data and plug it in the OFX particular x and y 
emiter the emitter is way way way way out of frame

to keep it in frame you need to use values like 0 to maybe .2 before it out of 
frame.

now I am not using a camera I only wish to use 2D point to drive the particles 
as you can very simply in AE.

Hey guys

I am wanting to use the particular node (not the 3D particular gizmo) and 
attache 2D track data to the emitter.

Problem I am having is that the numbers / data dont seem to dont seem to match 
at all (nuke x y to particular x y)

It works all fine in the AE version tracked x y data from nuke to particular.

Is there an expression that converts this data over.
