sorry I'm pretty new at this but I was following some tutorials to vertex hack, and when I preview the model file in brawl box to see what vertex group I need to export to change, the preview is empty.
any suggestions on what's going wrong?
You might have to zoom out (with the mouse roller). Then hold ctrl and use right click to rotate, right click on its own to slide.
That worked, thanks for the help I've been trying to fix that all day :)
... though now I feel kinda stupid, lol
