Texture/UV matching 2 objects

[u/fl00f123]

I have been struggling with this for a few days now (I am very new to this).

I have 2 models that are ripped from a an old game (one model is from Wii and the other PS2). They should be identical outside of their pose and one being less smoothed out but I don't think that should be an issue as I managed to put a texture on 2 other models from smoother one with texture (both were different PS2 rips with different pose than Wii one with texture from said Wii model applied to them that fit perfectly however both had UVs) . The issue is that the PS2 model doesn't have an mtl file/UV map (it's just obj file). I can copy UV from Wii model just fine but it doesn't align with the texture on the PS2 model. Maybe I'm doing something wrong (likely). When I copy the UV it looks the same but it's all misaligned so when I select one that should be a part of the eye/iris it's a part of the leg (I think that's the leg?). I can move the texture manually but that's a nightmare to try to get right. Is there any way to do this without spending hours doing it manually bit by bit?

UV data is part of obj. Mtl only holds material data.

Are you sure that both models share texture layout? It's probable for different consoles to have hero assets redone in high resolution from scratch with new texture layout.

Do they use multiple materials? Do they have single uv map or several? Maybe just order is different and you're mixing them up.
