Start by opening Sketchup and "Get Models".

Use the Scale tool to reduce the size of the ball ... make it pretty small, as shown:

Now you will want to move the ball until it is centered on the red/blue/green axis point. HINT: Move your view way up close to the ball so it is large on your screen to make it easier to make fine moves as you center the ball on the grid lines.

Now use the 3D-RAD Plugin in SketchUp to transform the SketchUp model into a DirectX model for use in MikuMikuDance 7.39 (You can get info and Downlaod that Plugin from the LearnMMD.com pages: HERE ... also see the CONTENTS on the LearnMMD.com's home page for still more info. There's a lot to learn ... Let's Learn How to Do Everything!)

Save the new ball.x file inside the Accessory file in the Users File in your MMD folder.

Open MMD and LOAD the new ball accessory.
You should see this:

Create a direct-x accessory model in SketchUp for use in MikuMikuDance 7.39

How do I make an accessory for MikuMikuDance 7.39? How can I use SketchUp to make Accessories in Miku Miku Dance 7.39? How do I use Google Sketchup to make a DirectX model? How do I get a ball for MikuMikuDance 7.39?

Using Google SketchUp to make Accessories for MikuMikuDance is a powerful tool that you will want to learn. To do so, you will need to add the 3-D RAD plugin to your SketchUp program so that you can save models as DirectX files ... with the .x extension that MMD 7.39 will recognize.


If you haven't already got that plugin, go to my DOWNLOADS page and find the link to get your 3D-RAD plugin. Follow that link to get info and instructions for using the plugin. The pages of LearnMMD.com have several articles covering the use of the 3D-RAD plugin.

To start this excercise, Open SketchUp and click the Get Models tab at the top right of the screen.

Choose any model you wish ... I chose a Pokeball because I want to create an animation with Miku Hatsune tossing around a Poke-Ball.

Use SketchUp's SCALE tool to resize the ball to suit your needs.

Now move the ball to center it on the center of the 3-axis grid. You want the axis lines to pass through the center of the ball so that your finished model will rotate smoothly as you use it in MMD 7.39. The relationship of the axis grid to the model, here, transfers along with the model as you transform it into a DirectX object and then open it in MMD.

Select and Delete the Woman figure ... or it will become part of your model.

All set to convert? Go to the PLUGINS tab, select the 3D-RAD plugin, and choose: Export as Generic DirectX (include backfaces), name your file, and choose to save it into the Accessory file inside your Users folder inside your MMD folder.

Now ... open MMD and LOAD the new accessory. See that it arrives attached to the Ground. You will want to LOAD the Dummy Bones ... and then come back to the Accessory mode and attach the accessory to a dummy bone. 

See the enclosed illustrations ... read more about Dummy Bones ... and away you go!

For my character's pose, I took the shortcut of using a saved hand pose: Right-Hand-Relaxed-OpenRD to give that nice shape to the hand. You can DOWNLOAD all of my Hand Poses and save inside your Users Pose Folder for your future use.

Have fun ... keep practising ...
Keep 'em dancing!
















































Move on to the next step in "tossing the ball" by creating the ball's motion:

Start tossing the ball by setting uo the ball's motion in MMD 7.39
