@B_Layer The last release should fix this at least the “bundled” version: https://github.com/eliemichel/LilySurfaceScrapper/releases/tag/v1.3.4_rc2
@rashomon Missing buttons suggest that there is an error, go and look at the system console (and copy paste it here so that I can tell more)
@atekdigitalYou must link the UV to the “Vector” input of the mapping node, not to the “Scale”
@AlexeyAdamitsky @Tosky I did not really grasp what you meant about a custom folder. For quick tests without having to save the file, I recommend setting up a common folder in the add-on preferences so that all your scenes share the same texture bank. This way if you use the same texture in several scenes, it is not downloaded again.
