MX Simulator

Hey fellers im new to skinning and whatnot. Have created a few jank bike skins and gear skins to get more used to importing them/testing the waters. downloaded a husky and instead of the jm's i have a singular blend file. Would I have to name that a certain way or convert it to a jm file? Much appreciation.

You’ll need to export the 4 JM’s yourself from the blendfile.
Frame, swingarm, fork upper and fork lower

10 4 buddy. thanks. had some issues but got the jm extension from jlv and figured er out. much appreciation.
