As the title says, after using the Ctrl+J shortcut to merge several objects into one, and exporting to OBJ and then opening in Pepakura Designer, it acts as if I never connected them at all.
It's a helmet, and more specifically, the unfold in pepakura unfolds all of the separate objects and, if i managed to assemble all of the parts, I'd finish with 6 unconnected parts instead of a full connected helmet.
So, can anyone help me? I'm extremely new to Blender and have no idea what to do. I've been looking for a few days now.
Thank you all.
