Wow, that's a lot of sudden technical autism.
>>2884403You need to elaborate on what you want. Anyway, I don't think you can do anything on the controller's side in regard to what involves InverseDir, and I doubt there'd be a noticeable drop in performance from simply inverting three floats compared to using an extra matrix just to get its rotation, but +カメラ doesn't seem to have any real purpose if you change the controller to PMX, so, assuming you can change the default matrix orientation using bone/offset links (possibly using the local axis feature), you only need to reparent it to 注視点 and append カメラ's rotation. I suspect the default orientation cannot be affected by bone links, however. If so, a bone morph rotating +カメラ by 180 on Y is your best bet, without reparenting and rotation appending.
>>2884458Which can be fixed by averaging normals based on distance, PMXView > Edit > N > V.
>>2884470Impressive but excessive for common MMD purposes. I think rig matching/retargeting will be a pain, and the best features shown in the video are unlikely to be transferable to a normal MMD rig or even the VMD format, which defeats the purpose. Might just use MMM or Blender to animate if convenience is your sole concern.
>>2884507What _did_ Vortex00 make? It seems he mostly just repurposed other people's works, so he has no dedicated folder on my machine. You will find a couple if you search archived.moe.
