Hey list,

I want my particle-system to change from channel a to b in frame 50. Therefore 
I take a particleExpression Node and write frame==50 down in the "chans"-field 
and "set to" to b.
The Particles change to channel b now, BUT not all of them in frame 50. It 
seems that "frame" is somehow relative to the frame where the particle was 
emitted.
Is that expected behaviour? 
In the end I want to freeze my simulation at a certain frame, is this the right 
approach to do that, or is there another way?
And as it is my first day playing with Nuke-particles, is there a way to debug 
stuff (e.g. to see which value is passed to the particles from that 
"chans"-field)?

Thanks,
Thomas

P.S.: there is a simple sample scene attached
