use <lora: m3tal: > in your prompt
M3tal Lora - is Tuned on images that I did specific post processing work on, in order to tune it for depth and metal detail, something that I haven't been able to find in the quality that i was looking for.
This is v1, I plan to update it and improve it further. I look forward to seeing what you create friends.
It does very well with other textures not just metal
(TIP: A powerful LoRA for Control-Net)
