src/Saba/Model/MMD/MMDCamera.cpp

        rot = glm::rotate(rot, cam.m_rotate.y, glm::vec3(0, 1, 0));
        rot = glm::rotate(rot, cam.m_rotate.z, glm::vec3(0, 0, -1));
        rot = glm::rotate(rot, cam.m_rotate.x, glm::vec3(1, 0, 0));

Question of rotation order?

It is VMD specification. https://blog.goo.ne.jp/torisu_tetosuki/e/bc9f1c4d597341b394bd02b64597499d

I also confirmed that it works the same as MMM.
