Converting PMX and PRM files to VRM

[Fatuous Lord]

What the title says, does any of you know how to go about this? Been trying to help my friend for the better part of the day and I haven't been able to figure out a way of doing this. There are videos online but sadly they're incredibly long and confusing. Perhaps a more clear-cut explanation can be offered by you guys here.

Thanks in advance!

Do you mean to FBX format, which Wakaru uses? PMX to VRM isn't really covered here since it's not VRM that you need as your final format.

Here's a backup of the instructions for PMX to FBX or VRM to FBX. Delete the space after "https"

You might need an older version of MMD4Mecanim to use the proccedure there. You can get one from here:

Kukushie also has a video tutorial that works with newer versions, though I'm not sure if physics work with that method..
