On my second day of learning MMD I took Unryuu's model and attached Yuuka's head to it. In the MMM, I promptly noticed that her arms get fucked up if you bend them. After an hour or more of attempts to fix it by moving bones and resizing body parts, I was able to deduce that it is due to my moving the body upwards in the editor. (The feet of the original model, clad in fancy shoes, go below the ground level.) Returning her to the original position indeed fixed them, but what the fuck, seriously? Why do they get fucked up if you properly put all her components on the floor level in the editor? Is there something I'm missing? It would be kind of annoying to constantly have to adjust her position manually if I were to use it often.
