This lora is trained on 6-8K images of dirt, rust, scratches, dust, peeling paint etc. It will give objects a worn and aged look. For people or animals it works as a detailer (oftentimes).

Because the training data consists of high frequency details, going down with the Guidance to 1.8-2.2 will certainly help to retain them.

Strength 1.0 can sometimes produce 2d/abstract results with some seeds. Just change the seed or lower the strength to 0.8 or so.
