Playing with MME – Using the Basic Effects for MMD

Hello fellow MMDers!! (^^)

You might be extremely fascinated with the various effects that are used in MMD videos that you see on YouTube. Here I am going to show you how to use the basic effects in MME; before we get into the more sophisticated ones. =)

First we will start with the popular “Diffusion” effect! This effect is very gentle and is known to make the models look softer, giving the screen a bit of a soft blur.

In this picture I have tried to show you the “Diffusion 7” effect. I used the version 7 as it gives a clearer view than the previous versions!

Diffusion 7 gently blurs the hard lines and softens the shadow edges.
Download the effect here. Just click on the name of the file and it will automatically start downloading!
Select Diffusion 7: [It is just below Diffusion 6]

Now to use this effect:

1. Open up MMD and load a model. [REMEMBER] MME effects will only work for the users who have installed MME into their computer and have interlinked it with MMD. DOWNLOAD MME Effects (MMEffects) from LearnMMD’s Downloads page!
2. Under “Accessory Manipulation” click on load; and then go over to the file in which you have saved your diffusion effect file.
3. Once you have found the file, open the file and click on the “Diffusion.x” file and the effect will be loaded!

And now you will have your model looking softer at the edges with a gently blurred look! (^^) … You can turn the effect off and on using the Display check-box. Be sure to Register when you click/unclick the Display box.

These steps can be applied to the Snow effect and the Blizzard effect.
Refer to the pictures to see how the effects look!

The blizzard effect is easy and dramatic!

The Snow Effect ... just looks cold, doesn't it?

Also, below, is a lovely effect known as “Falling Hearts” where hearts replace the snow!!
This effect was made by an MMDer named RinnyKagamine!

The Falling Heart Effect is just a wonderful effect ... gorgeous!

Download link for the “Falling Hearts” effect:

Refer to her site for other effects too!

I will explain about other effects that are to be applied to the model manually in the next article of the “Playing with MME” series!

If you have any trouble with these MMD Effects, email your questions to LearnMMD@aol.com and I will help you with any of the effects. I’ll try to sort out any problem that you may face.

Also … don’t be afraid to experiment with new effects. That is the motto of an MMDer!! *laughs*
You will learn more about MME faster that way!

    When I load up diffusion, the plain white background turns black. How do I keep the white background with diffusion?

    Is there a way to bring the falling effect in front of the model instead of only in the background behind model/stage?

    • May 26, 2018    

      Select “background->accessories edit” and experiment with accessories’ drawing order and the “over Nth accessory described after models” setting in particular.

    I have a question. For having the falling effects, is there anyway to make it continuous? I have this sakura petal falling effect and it only lasts for a little while. Trying to make it start again makes it look very awkward. Anyway to fix this or make it a less awkward transition?

      The effect is indeed awkward… in fact it’s not even an effect but a model with a preset motion file. Enhancing it for a longer period of time is… not quite impossible but involves a lot of menial work. How about simply using a different effect for sakura petals? Beamman has a nice one, for example.

    Hi, I am quite new to using MME… Is the OneDrive down or something? I cannot see the files there

    I’m asking about the snow effect. I saw this video where falling snow was falling at a slower pace than usual, the same with the falling glass effect in the video. How did they do that?

      Open Falling hearts.fx file in a text editor and find a following fragment:

      float Speed
      = 10;

      Replace “10” with another value more suitable to you and save the file.

      And if you feel adventurous, read the following article to learn how to make an universal customizable effect once and for all:

        Sorry, the engine mangled the code fragment I tried to post above. Trying again:

        float Speed
        = 10;

          Damn. Once more:

          float Speed
          \ = 10;

          • KillerBeer KillerBeer
            June 6, 2015    

            float Speed
            string UIName = “Speed”;
            string UIWidget = “Slider”;
            float UIMin = 0.0;
            float UIMax = 40.0;
            > = 10;

    Actually, the Accessory Edit screen should already say “0”. Just hit “OK”. If it doesn’t say zero, do what Reggie recommended.

    I have passed you question to our authors … stand by for emails! What effect has the problem for you?

    • Reggie_Dentmore Reggie_Dentmore

      Use the Accessory Edit screen in the Backgrounds tab … select your effect, there, and set that little “1” near the bottom of that panel to “0” zero … that should do it. … Yes?

    Page really helped!! Just wanted to ask why do the effects go THROUGH the model…? I mean, I’ll set it in front of the model and it’ll just not show up and it looks like it’s behind the model ;-; I need help *rolls on floor*

    I wasn’t able to use “Diffusion 7” because the site was down. But I did learn how to use MME on other effects. Again, thank you for making it simple to comprehend.

      Thank you, Scott … Thank you for checking into it and trying out the effects. I visited all of the sites and determined that they were working before we posted the article … so go ahead and try ’em again, they should be OK. I am looking forward to posting YOUR article one of these days “:o).
