Now that I am more or less caught up on motions, I’ll be back tracking to any motions I missed previously. Either because their distribution location was unorthodox or because I didn’t get the password on my first run.
The queue right now is set to post three times a day, but any new motions (as in motions posted from today onward) will take priority in the queue above anything else.
I’ve also decided i’ll post motions with the “Use only on Nico Douga, Twitter, and Youtube” rule as text posts, and a note about said rule. This won’t be as exciting as the other posts, but I think it’s the best I can really do.
Also this is a reminder that vmd files frequently have rules, so please PLEASE read the readmes before using them.
MMD Tutorial - Turning Physics On and Off mid-video
[In the above video, Miku's physics are on until she begins posing. During the poses, the physics are turned off to avoid aggressive movements. Physics are turned back on once she returns to normal Choreography. Teto's physics are unaffected.]
This will be a not-so in-depth explanation of the On / Off physics mode of mmd. On this blog, I frequently use this feature to avoid skirt clipping when a model is sitting down or aggressive clipping if a model is temporarily below the floor.
Above is the different physics options for MMD.
On / Off Mode (allows for physics to be individually turned on or off via key frames.)
Anytime (Physics are active at any time during playback or otherwise. Ignores keyframes.)
Trace Mode (Bones with Physics are loosely calculated as you move forward on MMD's timeline. Going back or skipping to a random spot on the timeline resets their position.)
No Calculation (Physics are OFF at all times)
The example I'll be using is kmk's Tell Your World motion with YYB's NT miku, which begins with the model crouched on the floor. The goal is to adjust the skirt so it's not clipping through her legs and remains still until she goes to stand.
With the Physics mode set to No Calculation, locate the row of bones on the view display for the skirt. For this miku, that will be row Null_372 (bc this miku's view display isn't translated)
Then (again, with it set to No Calculations) you'll adjust the skirt so it's laying over her legs more naturally. Then, register all the skirt bones at keyframe. (You can do this quickly by clicking on the entire row and hitting enter.)
Keyframes with an X on the timeline mean that is a bone with physics that's been registered there. A ◆ is a bone either with no physics or physics turned off. As you can see above, the skirt is currently showing as an X on the timeline. (the highlighted redline)
With all the skirt frames selected, you'll go back to the physical operation dropdown menu and select "Change Physics ON/OFF frame."
In the box that pops up, You'll change the option to "OFF" rather than the defaulted "ON (X mark)."
This should change the skirt registered frames from X to ◆. This means physics for these bones have been turned off and will remain off until registered again.
Note: Occasionally after you first do this and turn physics calculations back to "On / Off," the physics will still remain on. Playing the video or moving on the timeline should fix this so they're off.
Turning Physics Back On
This is more simple. Usually, I'll copy the keyframes for all the physics bones that are turned off first. I'll then find the frame in which I'd want them to be turned back on. I'll past the ◆ turned off keyframes there. The next frame I'll register all the physics bones again with the enter key. The resulting keyframes should be X, showing they're turned back on. From this frame onward, physics will move as normal.
Please see the above video to see me quickly going through the process for this tutorial!
This can be used for a lot of things but it's particularly useful for skirts or for motions that teleport models. For teleporting I'll register all the physics bones (ON) two frames before the movement. The frame right before the movement I'll register them all (OFF). Register them (OFF) again right after the movement, and then back on right after. It'd look something like this.
But ofc you should play around with these things and use them as needed.
I've decided to occasionally post motion-related tutorials on this blog. It's going to mostly be small tips focused on things like making mmd motions easier to use, explaining useful plugins / programs, or mmd features that might not be so commonly known.
It's going to be a sort of "when I have time / When I think of them" type deal, and will be posted on the weekends in place of a motion post.
If anyone has anything specific they're curious about, lemme know!

Note: This motion requires placement adjustments of the センター, グルーブ, 腰, and 上半身 bones, and the addition of the 上半身1 and 全ての親2 bones. Please make these adjustments for best results. The included readme goes into more detail.

Password Hint Translation: I unfortunately am struggling with this password hint translation. From what I can tell, the middle part is most likely a phrase from their online terms and the last part is asking for the number that's in the message you get when you like the video. If anyone can get a proper translation so I can update the post, I'd appreciate it!
Note: Videos using this motion may only be posted on youtube if you first post the video on Nico Douga and register it in the content tree. Posting on Bluesky and Twitter is ok as long as you include text credits. You may not use this motion in videos on accounts where you're active as a vtuber or in conjuntion with game rip data.

Note: The Readme and Distribution Video Credits give credit to 田中佳奈子 (Kanako Tanaka) for the choreography. The choreographer's name should be 田中彼方 (Kanata Tanaka) or はまっち (her nico douga username). Please be sure to credit her correctly when using this motion.

Second Note: This motion includes a microphone and guitar ripped from project diva. The microphone is not adjustable, and the mic itself does not move with the mic stand. I placed them slightly off to the side because they're too tall for the models i used. The guitar contains a VMD, but it does not contain placement information. I OP'd it's center bone to Len's upper body bone and rotated it to fit. It's size is also not adjustable, so it may be too big for some models as well.

Second Note: You MUST turn off the Toe IKs for this motion to work properly. This information is not included in the readme with the motion, but the feet will not look right otherwise.
