Good news - No more scene duplicates on appending (Patreon)

Just wanna share that I've finally figured out why appending my models caused duplicated scenes : it was because of the driver I put to disable ambient occlusion for cycles.

I'll get rid of it and will be using a script instead that will do the same plus some other stuff.

This will only affect future models but if you want to avoid those unwanted scenes with older models you just need to delete the driver that is in the shader group. If cycles is your main render you'll also have to change the factor value to zero where the driver was.
