creating a mesh in unity

hi i was just wandering if someone could clear up something about created meshes in unity, say i take a imported fence and modify it in unity using something like gamedraw, what does this add to my game, does it increase the file size as its a new mesh

In the case of GameDraw, No you don’t get any extra size as long as whenever you modify something you save it and when you want to reuse it you reuse the saved copy without editing it as each edited mesh is basically a new mesh, btw did you got the chance to try the latest updates of GameDraw, we’ve done a ton of improvements and even we have a lite weight mesh format that you can use for streaming your assets which is less than 1/10 in size compared to .obj but of-course you will need to use the API associated with it to do the streaming.
