How do I mint a 3D artwork on Foundation?

 Connect your wallet to access the site, and click on the "Create" button in the top right hand corner.

 

  • Submit your work in GLTF or GLB format. We accept files smaller than 50MB. This artwork file will be tokenized and represented on the blockchain.
  • Separately, this file will be lightly compressed when it’s displayed on Foundation so that it loads quickly across the homepage and elsewhere.
  • Preview your NFT before minting it and make sure that it looks all set.

  • Add a title and description to your artwork. Confirm that these details are completely correct before you mint an NFT.
  • Upload artwork on Foundation via IPFS (InterPlanetary File System), a peer-to-peer protocol for sharing data in a distributed file system.
  • Once you’ve uploaded your artwork, click “Upload” to send your artwork to IPFS where it will be stored.

What are the different 3D file types I can upload on Foundation?

Foundation currently supports two different file types for 3D artworks: GLTF and GLB. The max upload limit for files is currently 50mb.

 

How do I preview my 3D file?

After you upload your file you should check the final version using the preview feature on Foundation, you can also preview it on Model Viewer

For Desktop Previews:

For Mobile Previews:

  • Before you mint, we recommend copying and pasting the preview link from Foundation and testing it out on your mobile device. This preview will show you exactly how your file is going to behave on your mobile device once it is minted.

Why is my file taking forever to load?

  • The load time and performance of the 3D model depends on a lot of factors like the number of polygons in the mesh and the size of textures.

Do I need to upload an AR file?

Foundation automatically generates the USDZ / REALITY files for the Mobile AR Viewer when you upload a GLB file.

Before you mint, we highly recommend copying and pasting the preview link from Foundation and testing it out on your mobile device. This preview will show you exactly how your file is going to behave on your mobile device once it is minted.

What could cause AR not to work on mobile?

  • Unsupported shaders and complex animations inside the glb/gltf can cause problems for the AR feature when converting to USDZ
  • AR does not work on Chrome for iOS mobile

Guide to exporting 3D files in Blender

Blender

  • Blender is free and open source, and a community favorite in the 3D world.
  • Go ahead and download any version of Blender 2.80 or newer, it will have automatic GLTF/GLB import and export support.
  • Feel free to create your piece in the 3D program you feel most comfortable with, and then exporting the final as an FBX or OBJ into Blender
  • Once you have your file in Blender you can do your last pass of optimizations for export.
  • We recommend using our preview feature to test your files before tokenizing the piece. It will probably take a few passes on export and testing to get it right.
