Use 2D Background Images in MikuMikuDance

Use 2D Background Images to make pictures and videos in MikuMikuDance!

Hello Everyone!

Today I will show you how to use background images to your advantage!
(Please note: This tutorial will apply mostly to picture making, but some of the methods and techniques that I use here can come in handy in your videos, too.)

First, select one of your own photos or browse DeviantArt or another website with good stock photos and find one you can use. (Remember to credit the person or group who makes the stock photos). Here I’m using a fence scene, taken from Moon_WillowStock on Deviant Art. I’ve edited it a tad bit ahead of time in GIMP, but this method will work well with an unedited photo, as well.

Use 2D Background Images in MikuMikuDance

Try to adjust you screen size as close as you can to the pictures dimensions. By going to View> Screen Size.

Move the coordinate axis down so that it is pretty level with the ground in you picture. Do this by adjusting the camera angle.

Move around with your camera a bit and lower the view angle to about 25, so it matches up with the ground accurately.

Load your model, pose her (or him) up, and move the camera around the 3D space to a position that makes sense. When working with a 2D background the camera will offer more help positioning a model than the model itself. HINT: Getting rid of the axis might help you with this step.

Now, remember to register your camera. Then, add a diffusion effect. If you can’t get Diffusion 7 on your computer because of your graphics card, you can use Diffusion 6 which worked on my old computer just as well as Diffusion 7.

If you want to leave the picture like that, that’s okay. If you don’t, crop it and sharpen it in GIMP or Photoshop.

    Every time i am trying to add a video as background it sais “Cannot open AVI file”

      MMD is very picky about the type of video it accepts. You can use Format Factory free software to recode the video into “AVI type 1”.

    Omgkat: If it is a solid gray surface at the floor level, turn off “display ground shadow (S)”. Read here for more details: https://learnmmd.com/http:/learnmmd.com/adjust-the-shadows-in-mmd/

    Hi. I have used MMD for a couple of days now and whenever I try to load a stage or background there’s always a weird grey platform/floor that won’t go away! I’ve been trying to look on the internet, but it was to no avail. I have the latest version of MMD and have little or no issues on my computer. Thank you!

      I believe that’s an easy one … Under the VIEW menu you want to uncheck Display Coordinate Axis(G).
      All good, yes? Have you seen our “Start Here” page for step-by=step MMD instructions? It might help you enjoy MMD. Please ask questions!
