What's a fashion design contest?
VRoid Hub presents the 3D Model Posting Project Costume Challenge.
Summer is all about swimsuits, yukatas, summer delicacies, and sometimes bugs too! What does summer mean to you? Create an original 3D character, design and equip items, or dress up your avatar in your favorite outfit based on your idea of summer!
You can use any type of modeling software, paint software, or clothing design tools you like to create your 3D model. So long as your model is VRM format and can be uploaded to VRoid Hub, it's fine if you didn't design your model using VRoid Studio. You can also enter 3D models that you built from scratch.
For this contest, you can of course use original 3D models and fashion items, as well as items you commissioned or purchased, or you can use your favorite avatar you already use as a model.
We're waiting to see your totally unique Summer fashion sense!
Link BOOTH items to keep a record of your virtual Summer costume!
When you post your 3D model on VRoid Hub, you can link BOOTH items (items available on the BOOTH Global Marketplace) to introduce the models and items you've created and made available on BOOTH, or your favorite items that you found on BOOTH!
How to link BOOTH items from your 3D model
From the model information editing page, go to "BOOTH items" at the bottom left of the page, and click the + button to open the BOOTH item registration page. Enter the URLs for the BOOTH items you would like to display, and set an item category for each item.
You can register up to 10 items.

If you register BOOTH items for a model, the BOOTH items will be displayed with thumbnail images on the model's character model details page.

Please feel free to share your favorite items for dressing up your 3D character!
