It turns anything you want into a blackberry/made out of blackberry/with a blackberry surface.
trigger: blackberryworld
Put the trigger word before the desired noun as an adjective and after that all the additional details.
For example: blackberryworld dress on a middle-age natural blonde woman
It's my first published LoRA and cuz I trained it on images with a plain blurred background, it tends to create pictures with monochromatic or gradient background, if you don't further specify this. So add more details in prompt and it'll work.
