Editing MMD Model Eye Textures enhances Ray-MMD Effect

Hello guys, today’s a great day for me. It’s my first article here, so enjoy!

I have heard a lot of MMDers saying :

“Why does my model have dark eyes when I use Raycast?” And, “My model doesn’t look right with RayCast! Raaaah!”

A sample of what it looks like when a model’s eyes are dark when using Raycast…

Then, I found the answer to theses problems.

Btw, before I start, I want to credit Reona because their tutorial helped me a lot.

Editing MMD Model Eye Textures…

1) Open PMX Editor

Drag and drop your model in the editor.

You can disable the bone view at the left bottom of the view tab.

2) Faceforward plugin

You’ll need the Faceforward plugin to make this work.
(… Just a note: if you English-translate that Bowlroll page, you will see that the effect is called “Orient the Normals”… but when you open that plugin in PMXE, you will see it as Faceforward…)

Just put it in the Plugin folder.

Back in PMXE, click M in the view window and deselect everything (R). Select only the face.

Use your mouse to select the face again in the view window.

Now, activate your plugin Faceforward 64 (for 64bits computers/PMXE, 32 for 32bits computers/PMXE). A small window in Japanese will open itself.

The first rectangle is the one we need to modify. Choose a value between 45% and 65% (it’s my personal recommendation, but only your choice matters)

Don’t touch the other values

Then click OK (the clickable button of the window)

Your model face looks more flat now, that’s exactly what we want.

3) Separate the eyeballs from the pupil

For this one, you need another plugin : Doru formula UV editor

Open the brand new plugin (UV Editor) in PMXE. It will take time to load, that’s normal. Up to 6 seconds if everything is okay.

You’ll see a window open itself with the textures of your model.

In the top right of UV Editor, select 目 (it’s the eye). The texture of Miku’s eye should appear. With your mouse, select the small white circle (the meshes should now be red) and click the second big button. Now, Miku’s eyes have some orange dots.

It should look like this :


We’re almost there!

Now, close UV Editor (no need to keep it open) and do Ctrl+F (to show faces).


Miku’s eyes are now red.


Let’s add the eyeball as a new material.

Click Edit, then Face, then Truncate.

We’re almost done!

4) Give a name to your material!

In the small window with a lot of information on it, click the Material tab.

The last Material is named New Material1.

How awful! Let’s change the name!

I named it 白目 meaning White Eye (Eyeball) in the Japanese tab, and Eyeball in the EN tab.

Japanese models aren’t always translated into English, so if you name your material in that English tab, you’ll immediately see it.

Now, you’re done!
Your model is now looking good in RayCast!

I highly recommend you to put a Color Change material to make the eyeballs pure white.

You can find the first version of the material here : Color Change Material 1.0

And the 3.0 version of the material here : Color Change Material 3.0

My recommended values :

R = 200

G = 200

B = 200

If those values are too high, it will seem too bright.

This has been Reika, aka Eien Kiseki-P. … Thank you for reading!

See you next time! (≧▽≦)
