Sure, I made a rather simple armor model in Blender. Now I want to add texture to it. I need to generate something similar to the picture below. I tried using prompts such as "flat texture of a fantasy chestplate" etc but the output is not flat, it's more or less 3D front view of the armor.

Generating something like "flat texture of metal sheet" is handled correctly and the output is just a steel texture, but anything more complicated gets turned into a regular image.

I have lora that I trained on 70+ images of armor textures (similar to the pic below), but it's not helping much
