There are 20,000 unique Meebits registered on the Ethereum blockchain. Owners of Cryptopunks and Autoglyphs NFTs were entitled to mint a Meebit per each punk or glyph they owned.
There was also a public sale in which 75M worth of Meebits were minted in a single day, creating a combined total of 4400+ owners of these unique 3D characters.
These thousands of new Meebits owners represent the latest wave in the cultural forces that are accelerating Metaverse interoperability. In this guide we'll show you how to convert your Meebit into the
VRM format, the best open standard for avatars. From there you can bring it into Webaverse and many other platforms. Pre-requisites Convert Vox File Download the 3D Voxel model file (T-pose) from the Meebit page Open vox file in Magicavoxel to convert a. Open the T-pose vox file using the folder icon b. Click export and select obj option to save Rig in Mixamo
Next we need to add the skeleton rig so our model can have bones. The easiest method is through
Mixamo, a free service from Adobe.
Zip the obj, mtl, and png texture files exported from Magicavoxel together then upload the zip to Mixamo.com to rig.
Set the positions like so with 'No Fingers' and hit next. The auto-rigger will take care of the rest.
Upload the zip with obj files to mixamo, add points, set No Fingers on bottom
Now just download the resulting file with the default settings: FBX Binary in T-pose.
After you rigged the model, download it without changing the default settings Convert to VRM Download the latest
UniVRM-0.xx.unitypackage version of UniVRM:
