Hello.
That second model had a shifted cent.
I gave an example where I changed the cent and baked the texture and worked on the model a little.
In general, if you make games with 3D capabilities, you need to master at least a few editors at a basic level. For baking and adjusting models.
If you want the game to have good performance in browsers and on smartphones, it is better to bake the texture and remove unnecessary vertices so as not to put a lot of calculations on the video chip.
After reviewing the models, it becomes clear why modern games consume more and more resources.
