>>2830380Including the edited motion from my archive? Does the stage itself load just fine and let you tweak its morphs?
Then try loading these in MMD and MikuMikuMoving:
https://files.catbox.moe/s8t0q1.rarAre your graphics drivers up to date? Are you a Windows user? Have you rebooted recently? Do your system settings support Unicode characters? (Once, a desktop shortcut with a Unicode character was needed to load the package immediately after booting, otherwise they wouldn't work during the first run of explorer.exe.)
If not to any of the above, correct that and try again.
Can you name any other motions where the same thing happened? Do they happen to include any by A_minor/Lapislazuli07 (
>>2830051 )? If none of the four I've provided load anywhere and everything is up to date, well, maybe you can try butchering the stage itself, cutting out random large random chunks, saving the result separately, and testing the motions with that instead to see if it fixes your issue. Otherwise you will need to decide between using the stage with this motion and updating your rig, unless the issue solves itself randomly, like in at least one similar case.
