I just popped through the code and made it skip that functionality altogether when using Cycles. So, no “Copy to SSS” checkbox, it’ll just print the value to the “IOR” field.
I’m glad everything else is good with it. If you do come across anything, be sure to let me know and I’ll check it out.
the latter is how trunk scripts do, but just something cosmetically
a suggestion:
your addon has no category, as there’s no Material cat in stock Blender. But: you can simply set your addon to be category “Material” and there will be a new cat shown in User prefs! I think Material would be the right category and it makes sense to create this new one, there will potentially be new addons for material related stuff and they would go into this cat too.
I’m working on another addon which has more complex layouts than I’m used to, so I’ve gotten into the habbit of naming rows and such like that so I know exactly where everything is being placed.
I had no idea you could name new categories like that! I thought you had to conform to what Blender already has listed. I’ve made the change and updated the Tracker.
