Sorry, I couldn't answer you there, I'll use it here, regarding your question about how to modify the breasts of my character "Goblin Girl big tits", Yes, I use Blender 4.0. You import your model, look on the right side for "Armature," then the "Body" option. The Body option will select the body to modify. On the left side, go to the "Object Mode" tab and choose the "Sculpt Mode" option. After that, look for the "Elastic Deform" tool; it's an easy tool to stretch the breasts. Then, use the "Draw" tool to round the breasts and shape them as you wish.
