This is an Illustrious style lora for making muscular robots. The pictures used came from some neat pics I found on Pinterest, along with a few of my own pics made with AI. The colors are versatile and ought to be prompted, lest it default to black like with many style loras I have made. The same goes for head styles, since not prompting for a head type will result in the usual standard generic look.

A weight of 1 to 1.5 works well with this with most models. Sampling Steps of 15 to 35 works well with most models, as does a CFG Scale of 5 to 7.

Prompts for this lora are ( MusRob, muscular, robot, ). Adding ( no humans, angular eyes, robot body, robot head, ambiguous facial features, ) to the positive prompts helps with the robot look since some checkpoints and loras tries to add overly humanoid looks instead of robotic looks. Also, adding prompts to increase the muscular look for a more hyper muscular look tends to add humanoid features as well.

Adding ( nipples, hair, liquid, skull, latex, clothing, folds, creases, crystals, stone, aura, wings, spikes, human, human face, humanoid face, fur, fire, smoke, ) to the negative prompts section can help since some normal prompts and some checkpoints tends to meddle with the image results at times. Using prompts related to muscles tends to try and make regular muscles, which tends to make folds and creases, along with human faces and hair. And some checkpoints tries to add fur, hair, and regular humanoid heads. Since some checkpoints tends to make anime like pictures, it tries to add hair, smoke, fire, spikes, and wings. In some cases spikes, crystals, and stone tends to be added on the character for some unknown reason.
