Note most checkpoint's have training of Lacey Chabert, but the training appear to have blended multiple years and possibly other celebrity face data.
To use the lora generate at 512x512 or 768x768 (Wide or Portrait can also be used)
DO NOT use the name "Lacey Chabert" during generation this will cause the lora to fight the existing images.
During generation a Lora value of .75-1.0 is recommended
When up scaling a lora value of 0.25-0.5 is recommended
While up scaling using the trained checkpoint data of "Lacey Chabert" can be done however it is recommended to use a low value such as (Lacey Chabert:0.25)
Note for Auto1111 users this is not a lora prompt it is telling the checkpoint to mix in %25 percent of the name"Lacey Chabert" training into the mix.
Since the lora doesn't have the name "Lacey Chabert" it is mixing in checkpoint training with the Lora U-Net
