Well i was more thinking of the x position in the expression node. I wanted to turn some geometry into image data using the expression node ( like the ParticleToImage node), and though that I could iterate using the x and y offset.
But after a bit of searching I found someone who explained that it was not possible. However I did find another way to do it that doesn't involve tcl. So consider it solved :) Den mandag den 4. april 2016 skrev Gabor L.
