How to combine multiple meshes to a single mesh object?

Sorry, I’m a newbie and I’m also not good at English either.

How to combine multiple meshes to a single mesh object? for example for some reason, I need all of the custom prefabs in a character like a helmet type, face, weapons, etc after I select these things, I need it to be a single mesh object, for example, I need all of the object in the picture turn to be one object.

Please help, this is very important for me.

Why do you need them to be a single mesh object? That’s a very odd and unusual thing to need.

More likely you just need them to act like one object, which you can do by simply creating an empty GameObject, and dragging all the different parts into that.

I highly recommend using a different host for your images. They’re not showing up (nor can I reach the website by clicking the link) on my end and that’s highly unusual for my connection so they’re likely not showing up for a lot of people.

My problem finally solved, at last, Thank you very much.

glad to hear that. but how? and why you need it? just wanna hear it sorry to revive an old threads
