Maybe you’re asking about how I make LoRA? Here’s my process:

Step 1: I use some random images I find online to create a prototype LoRA on Civitai.

The prototype LoRA usually ends up with very flat colors (especially when made from anime-style images).

Step 2: I mix the prototype LoRA with another LoRA I have that features characters with a strong shading style. Using Stable Diffusion, I generate images with different angles and expressions, both nude versions and clothed versions.

Based on those generated images, I then create the final LoRA.

For example, with Ryza, I mix the prototype LoRA at 0.8 strength with kamisaki hikaru2/medalist（狼嵜 光／メダリスト） - V1 | Illustrious LoRA | Civitai ←this character’s LoRA at 0.5 strength to produce the image dataset for the second-stage LoRA.

Since I’m not very good at English, I apologize if this answer doesn’t exactly match the intent of your question.
