How to make models in Sketchup, and use them in MMD:
Goedendag lezers van LearnMMD. (Hello LearnMMD readers) In this article I will explain how to make your own models in Sketchup (formally Google Sketchup), and use them in MMD. We have some more articles about this, but those are outdated. The new Sketchup versions handle curtain things differently. Making models can seem to be hard at first, but once you know the basics it’s pretty simple.
You may have seen my masthead art on the site:
I have used my own stage in this image, below you can see more of the set I used:
Let’s get started:
On our downloads page we have a link to the Sketchup website (at the bottom of the page), Download Sketchup Make.
In the dropdown select for personal projects, then enter your E-mail address, select in the profession/interest dropdown whatever you wish. (I used film & stage)
Tick the agree to license box and click download.
Make your model in Sketchup.
Once you have it installed, open up Sketchup. Select the template: “Simple Template – Meters” (or Feet if you use the imperial system). Once Sketchup is loaded you are greeted with this interface:
It may look complicated at first, but trust me. IT ISN`T! I was able to use the basic features within a day, this program is easy to use, and there many tutorials online to help you. We even have a few here on LearnMMD.com like: The MikuBall tutorial and https://learnmmd.com/Sketchup_texture_directx_model/ But these are outdated.
For MMDers the main thing that differs from the old Google Sketchup, (Sketchup isn`t owned by Google anymore.) is that it handles plugins a bit different, mostly it’s the same though.
I made a rough sketch of my own desk with my PC and 3D printer on it:
Ok, how do I make a model then?
First thing I do is get rid of the person standing there, they will get mixed in your model if you don`t. Do this by selecting it and then press Delete.
To create a simple room press the rectangle tool, in the dropdown you can select different shapes if you want to create different shape. You can use the push/pull tool to make it taller, but since this is the floor keep it as thin as possible. To create walls, simply use the pencil tool to draw lines. Use the push/pull tool to make the wall taller.
Just tinker with the program, the basic tools speak for themselves.
You can also go into the 3dwarehouse of Sketchup and find models others have made that you can implement into yours!
Just download a model from there and open the SKP file. Just copy paste it into your model and use the move and rotate tool to position it.
It may be a bit hard at first, but if you do as I described above it should be fine.
Adding textures to the model
You can use the paint bucket tool to add a texture to the model. This can be a solid color, but also a material or photo.
You can use the stock textures provided by Sketchup, like I did for my floor.
Ok, so how do I add my own textures?
On the right of the screen you have a tray called materials, click on the + button.
You will see this screen:
You can give your texture a name, but I just leave the normal name in.
You can give it a solid color or an image, we are going to do this.
- Tick the box that says “Use texture image”
- Open the image file.
- Give it a size, this must be the same size as the surface you want to texture. You can use the measuring tape tool for this. When you enter your measurements click the chain, this will tell the program not to care about aspect ratios.
Now select it in the materials tray and click on the surface you want to texture. You may see that the image repeats on the surface, I had this issue too. I found this extension, the Texture Resizer Extension
This extension will help you to get rid of it. It does require a program to be installed, It is linked in the description of the extension.
To load the extension go to Window, Preferences and then extensions. Click on install extension, open the file you downloaded.
If you have done it correctly it you should have this tab added to the menu bar:
Click on align texture, it should fix the problem. It may still be off like I had with my monitors but it isn’t really visible unless you know it’s there.
Scaling the model so it fits in MMD.
MMD requires that the model is increased in size by 25%.
To scale it you can use the scaling tool.
Select the entire model and drag one of the upper corners, look in the bottom right corner of Sketchup. You will see your scale when you drag the corner, when the number says 1.25 release the corner. Now you should have your model scaled to the right size.
Exporting your model to an MMD friendly format
MikuMikuDance can`t read SKP files. It does read .X files. We can export to this format by using an extension, but this extension is no longer available anywhere.
Reggie was able to upload his copy of the extension to the LearnMMD website!
To install the extension go to the folder Sketchup is installed in. For me this is:
“C:\Program Files\Sketchup\Sketchup 2016”
Go to the tools folder and drop the file you downloaded in there, your folder should look like this:
Now open up Sketchup and you will see this tab being added:
Now click on Export as generic DirecX file (include backfaces), this will export it as an X file. This may take a while, even on my very fast system it does. If it looks like Sketchup doesn’t respond, just wait it out. When it prompts where you want to save the file you can select any folder, it doesn’t matter. There is a bug where it always saves to the documents folder no matter what you have selected. It will save under the correct filename so it is visible. It will also save the textures with it, these will be also be placed in the documents folder. What you need to do is to move the .x file and all your texture files to a folder within the MMD UserFile folder.
Open up your model in MikuMikuDance
Loading your model is the same as loading any other accessory.
Open the .X file through the Accessory Manipulation Panel. (AMP)
Check the model and see if the entire model made it through the exporting part, and if your textures are there. Sometimes the 3DRad extension messes it up, in that case try to export it again. When you have a missing texture check your documents folder if you forgot to copy it over.
For me it should look like this:
Now you may need to do some fine tuning in MMD like changing its position if it is off center.
Just edit the X Y and Z values in the AMP until it is in the right position.
That’s how you make your own model :D
From here it`s just like any other MMD project.
UPDATE 28-12-2015: Trackdancer has made an excellent article on Sketchup as well! Its a great way to take the information described here, and take it a step further!
You can try to add a bone to it by ether using a dummy bone, or edit the model in PMDEdit. I didn’t include that because I don`t have much knowledge of PMDEdit.
If you have any question or comments, please let me know in the comments. I will read them and try to help you as much as I can.
