>>28006331) Software other than MMD and MMM, which is capable of accurately processing softbody physics. (Establishing bridges between MMD and other software to process physics while rendering within MMD also counts as this.)
2) Very complex weighing with a fine mesh of deformation bones. (Looking at the source video, it doesn't seem likely unless the motion is manually keyed rather than relying on physics.)
3) Vertex morphs that fake real-time interaction.
4) BeammanP's PuniEngine, but only if it has considerably evolved since version 0.1.2.
The look suggests it's (1).
>>2800629>>2800640IDK how you arrive at these conclusions when the author just wants to ensure that the end user will understand and hopefully comply with their rules.
>>2800645As you appear to have the original link, have you tried yandex and web archive?
