Accessing onOne Software via File > Plug-in Extras > Perfect Photo Suite, a duplicate of the original file is automatically created and sent to the Perfect Photo Suite, in a nondestructive workflow. At the end of your editing session save and close the image from the Perfect Layers module.
The image will automatically return to Lightroom stacked next to the original file. Make sure you are in the All Photographs catalog or the original folder where the image resides and not in Previous Import or a Smart Collection.
The native file format for Perfect Photo Suite is .psd, however this can be adjusted to either .jpeg or .tiff file formats through the Perfect Photo Suite preferences. For information, please click here.
