Super useful. Thank you very much. Would be nice if that could work with both Map File or Streamed Map File. At the moment I have the feeling that it works only with Map File.
My script has the advantage of using only 3 nodes so it is a bit simpler to implement and easier to control. This is only for the "tiling" aspect. I hope you find it useful!
I've updated the script with a more user friendly set up and added some additional control - you can turn the tiling on and off to see the result by switching the OSL output.
I have updated the script to hopefully make it a bit faster - I have simplified the noise calculation slightly.
If you need to duplicate a script, there seems to be an issue in Clarisse with copy and pasting or duplicating an OSL script. Unfortunately this is an issue with Clarisse. In order to solve this you will need to open the OSL script itself and add a blank line at the bottom and then press "ok" to recompile it.
