Hi Andrew,

Thanks for reply, may I ask what nodes shall I use for indexing pixel? I
know the fit range can normalize however I'm quite new to index pixel
concept.

Cheers
herman

You need to index your pixel values on something that it resolution
independent. Using a normalized 0-1 "uv" index is a standard way. If the
patterns you want are created by 640*640 - then index on uv*640.

Hope that helps.
