You're right, I realized after I wrote that there was no blinking motion and deleted my post.
Thanks for the improvement.
I'm really glad I got your lecture. I appreciate it.

@eiron Thank you so much for taking the time to give me a lecture.
I've never done anything as complicated as adjusting the bones of a model, though I can manage to shape mmd by pouring it in, but I've never done anything as complicated as that.
I've never done any bone adjustments on a model yet, and I particularly liked Zy0n7's Rebecca.
So I started to convert the model, but there are still a lot of things I don't understand, so I'll learn more!

I checked the mechanical arm file right away and it looks great. It's just as I wanted it to be!
The site I looked at said to make it additive and set the opacity to -1, which I did, but it left shadows, so I was wondering why.

Is the method for converting to dynamic bones using PB2DB the same as the thread you posted to me before?
If not, I'd appreciate it if you could post the address again sometime.

And to the others who are watching this thread.
Sorry for posting my personal story over and over again.
But I'm grateful to have found this thread.

The file is up to pmx conversion and texture assignment.

What you can do yourself
Morph assignment
Morph accessories to make them transparent

What you can't do
Morphing out the shadows of accessories in MMD, but leaving the shadows on the accessories
How to shake the solid hair
The most difficult part is that the model's feet don't touch the ground when wearing the bunny suit, but when wearing the shoes style, they don't touch the ground, so I want to make them touch the ground with morphs, but I'm having a hard time because of my lack of knowledge.

Question
Is there any problem with the center bone being in the same position as all the parents?

I would be very grateful if you could tell me how to solve this problem.

@eiron
I was browsing the forum after I wrote it and found your vrc conversion article and managed to get it into shape.
Thank you very much for your help.

Now I'm trying to move the hair that's still stuck.
I'll study the model eiron made and compare it with the one I made myself.

Thank you so much eiron!

I'm using a translation engine, so I'm sorry if my writing is a bit weird.

I got Rebecca from TOP and tried to convert it to PMX but as a newbie, it doesn't work!
If anyone was able to convert it, would you please share it with me?
