<html><body><div style="color:#000; background-color:#fff; font-family:arial, helvetica, sans-serif;font-size:12pt">I am the developer of Gyes ( random material and texture generator). The reason why Gyes <br>use bpy.context.scene is to store a property that store presets of randomised materials / textures. <br>I wanted the data to be stored/saved with the blend file and be associated with the scene curently loaded <br>as global scene presets and not specific presets to objects or any other 3d asset. <br><br>I am not sure if removing bpy.context.scene is a good idea in the first place, unless there is another way to save <br>, store scene presets together with the blend file. If so , then gladly I will update my addon. But if not , it basically <br>cripples / makes useless my history tool -> <a
