Training on "black sclera". I have been working to integrate various unique features into LoRa's (and now LoCon). I have found making individual trainings on each feature, then merging the ones needed together gets remarkable results. Eyes are hard to get right, this helps but isn't a perfect solution yet though. This has been trained on about 80 AI generated images from various models (picked out from hundreds), after using a couple not so great lora's I had experimented with before. This can be used stand-alone to add black sclera with much higher efficiency, or mixed with other LoRA / LoCon to mix the feature in. I recommend to avoid using this with multiple other LoRA / LoCon without mixing first, it is more prone to cause issues. https://civitai.com/models/19320?modelVersionId=23770
