MMD Tutorial PMD to PMX Conversion by Trackdancer MMD Tutorial PMD to PMX Conversion by Trackdancer
A simple introduction on converting PMD models to PMX standard. Also serves as a general overview of some of the materials handling controls available in the PMD Editor when in PMX editing mode.


In some instances the leg IK structures derp after the conversion. This is due to a failure with the PMD Editor failing to read a script that is required to correctly constrain the leg movements. There are two fixes:

1. For advanced users with a good understanding of Windows:

This is actually the simplest solution. To prevent the error from occurring in the first place, simply correct the  title/filename of the script file. It should read: "IK制限角.txt" and the only lines in the file are as follows (verbatim):

左ひざ,-180.0,-0.5,0.0,0.0,0.0,0.0
右ひざ,-180.0,-0.5,0.0,0.0,0.0,0.0

This file is located in the _data folder and usually the filename is garbage which is at the root cause of the problem.

2. The standard fix is here:

No tutorial is going to make this process any easier. It is a very fiddly procedure and frankly the PMD Editor isn't the best tool for this sort of operation and it does need a lot of patience and a good level of skill to get right. Personally, I don't have the patience for doing something like this. But obviously some people do have the patience and skill to do this using this tool and I just their models.

An excellent example of something like this done successfully by someone with the patience/technique/skill to pull off something like this is this model by YamiSweet :

Hard to say with no info to make even an intelligent guess. That said it is rare that this happens and if I were to look for a root cause for the problem I would look firstly at the following:

(1) A corruption of the mesh
(2) A problem with the physics


All of these issues are complex and it's not easy to explain to a beginner. Try re-converting or have someone else do it for you for the same model (not me - I don't have the time). There could also be an issue with how the PMD Editor is running on your system and if it's not properly set up, such as being able to interpret Japanese language characters, this could be an issue too.

Ah i see, i would so love you, if perhaps you could make a tutorial, because you see i'm a beginner on MMD.
I do know a few things about PMD & PMX, though this one for me is kinda new.
I've seen this PMX slider on a TDA model before and i really wanted to do that, because i has a model that has a glitch hand, because there's two hands on the same spot.
''the original hand and a glove (Which is the same hand but textured lol). 
So, i don't wanna resize it neither make a model separately with the glove or vice versa.. 
That's why i wanted to use this slider, it would be like very helpfull..

I hope you can understand me, because my english is very poor and my grammar is terrible lol.
But thanks in advance if you do make a tutorial.. :iconmoesmileplz:

Also, could you do as well an tutorial about how to texture Pmx models?...
Like making they all cute like, uhmm... :iconlunassis:'s Cookie models?.

what version of pmd do you use? and where can i get it?
Reply
:icontrackdancer:
Trackdancer Featured By Owner Nov 10, 2013
I use two versions of the PMD Editor:

PMD (English) version 0.0.6.3 which is really a bit dated and cannot handle large files and PMX format models.

PMD version 0.1.3.9 which is the most current 32-bit application for editing PMD/PMX/x file models. This is the version I use the most, but it only comes in Japanese.

These programs are pretty popular. You should be able to find links to download these applications by using Google search or the DA search box.

I have never heard of something like this happening, but I have a rough idea what might the roots causes might be and it's probably hardware related. This is not something I can help you with as I can't physically access your computer. You will need someone who can to fix the problem.

Trackdancer Featured By Owner Feb 9, 2013
Mostly you cannot do it the other way around because you can't really downgrade a PMX model. You can do it manually if you know what you're doing, but it's a big hassle.

Sounds like you have not installed the software correctly. There are tutorials around on how it should be installed, just search for one of them. You're probably missing one or more of the three other components required to successfully run the application.

If the English translated one works, version 0.1.3.8 should also work as they require the same components. Something, else is going on. Maybe you're just clicking on the wrong controls. Can't tell when I can't see what's going on.

Which is better? PMD or PMX ?
I can't edit PMX and have only heard about trouble with leg bones with the PMX models.
Reply
:icontrackdancer:
Trackdancer Featured By Owner Dec 23, 2012
You can edit PMX models using the PMD editor (I do).

Which is better? I have don't have the exact technical information on hand to answer that question definitively; but I do have, from working with both formats, the impression that the PMX format has an upper hand in some areas. Also, in some ways, PMX models are actually a little easier to work with once you get the models inside MMD.

Certainly, the PMX format allows for more information about the model to be held in the model's data file.

I have been using the PMD Slim

PMD 139 is in Japanese I think this opens PMX. Could holding more information about a model lead to I having more Lag when in use in MMD?

Trackdancer Featured By Owner Dec 24, 2012
Could holding more information about a model lead to I having more Lag when in use in MMD?

Model efficiency is affected by:

1. the number of polygons a model has.
2. the size and number of texture files used.
3. the scope of transparencies used on the model.
4. rather more specific to MMD: the complexities of the physics computations needed by the model.

The size of the model file isn't such a big factor with a decent system. Most of it is just data which is only accessed when needed (but does need to reside in memory).

PMD 0.1.3.8 and up will open/save PMX files.

Noted!
I have 1 model (base)that operates @
26fps when set to 30. She is the workhorse to the timing of motion to sound. Similar (base) models operate
down to 14fps.

Got PMD 139 running now :D

:icontrackdancer:
Trackdancer Featured By Owner Dec 24, 2012
30 fps should be fine for most applications. I do believe that YouTube only supports 30 fps max., though I might be corrected on this point.

Actually, there's a standalone version of PMXEditor. From what I can say, it supports PMX format fully (compatible with PMX format version 2.1), with many external features for specially editing PMX models. It only works on 64bit versions of Windows, unfortunately; the explanation given was only 64bit OSs can ensure the requirement for modifying PMX models. There's also a 32bit version, but the author said it's just a test a might not function properly like the 64bit version.
