Not matching GCR for backtracking and average GCR

[ali]

Hi,

Why do I receive a warning like this? 

I imported a layout with GCR of .477 based on the row distance and panel size. 

Thanks

By default, the backtracking algorithm will find the lowest pitch in your scene (hence the highest GCR) as reference for the backtracking motion. This is what is indicated in this message, and it means that some trackers in your scene are slightly closer to each other than the others. This may be due to how the row distance was calculated in your initial layout.

In any case, this is not really a problem, but more of an information. You can, if you want, adjust the backtracking settings in 3D scene > Tools > Backtracking management.
