After many obstacles, I was on the verge of giving up and regaining confidence: over and over again, because I often didn't know how to import the model into mpn correctly, and I often had problems when making the 3D model of the body (I learned it later), but then I wanted to modify the bullet model for the grenade and I didn't know how to use it
I have no idea how to turn the image I made from my fla file into a 3d model made with blender and put it into mpn
