I was searching through the forums trying to find out how to make vehicles and open .mesh files. I downloaded blender because I heard that it is the best application for 3d modeling. But I was wondering if .mesh files can be converted to a .blender file?

They can be if you import the .mesh file and then save it as a .blender file. You just need the importing/exporting tools and you're good to go.

Hmm, alright. Making stuff in Blender is a pain in my opinion, that could be because I'm completely new to it.

Do you by chance have a link for the importer i need to convert .mesh files. I can not seem to find a live one

a *.mesh file can't be edited, it's a binary file.

I use this exporter for Blender:
