I see two issues actually. Is the first axe actually showing up like that? Because it means the UV has not been saved properly. As for the bottom weapon, it will show up gray because the texture path is only reading from the root texture folder. This is normal and the right way to do it. If you use the full path, like you have with the top weapon, it will show up properly in game(if memory serves me) but will not for others due to have different drive names, or paths, etc. Ops, see I did not explain good enough, my bad One the picture of the axe I added my own texture, that is why it's all messed up. Then I switched out the axe with my own model and added the texture, but then it only stays gray :/ So since the textures worked on the axe, but not the hammer I think it have to be some settings I have got wrong on the hammer, but I have no idea of what :/
