How to Export 3D Models from Blender for VRChat: Your Fast-Track Guide to 3D Model Export

Exporting 3D models from Blender for VRChat is a process that requires attention to both technical specifications and creative details. First, ensure your model’s scale and orientation are correct for VRChat’s guidelines: the avatar should stand upright and face forward in Blender’s perspective. Apply all transformations (location, rotation, scale) by selecting your model and pressing Ctrl+A. Check polygon count and material usage; VRChat recommends keeping avatars under 70,000 polygons and limiting materials for optimized performance.

For export, select your model and go to File > Export > FBX (.fbx). In the export dialogue, make sure to check Selected Objects and choose Apply Transform. Set the forward axis as -Z Forward and the up axis as Y Up to match the Unity coordinate system. If your avatar uses an armature (for animation), select “Armature” in the export settings and enable “Add Leaf Bones” if required by your rig. This FBX file can then be imported into Unity using the VRChat SDK for further customization and uploading to VRChat.

From a designer’s perspective, I always emphasize efficiency in workflow. One pro tip for fellow creators: if you want to pre-visualize your model in a realistic environment before porting to VRChat, use a 3D render home tool to check lighting, textures, and spatial interaction. This extra step ensures your VRChat avatar or prop not only meets technical requirements but also looks great in virtual spaces.

Tips 1:

Always name your mesh and armature objects clearly before export—this minimizes confusion in Unity and assists with debugging issues later on. Consistent naming also streamlines collaboration if you’re working in a team.

FAQ

Q: What file format does VRChat accept from Blender?

A: VRChat requires .fbx files, exported from Blender with appropriate scale and orientation settings.

Q: How should I set axes during export for VRChat models?

A: Use -Z Forward and Y Up in the FBX export settings to match Unity and VRChat requirements.

Q: Are there polygon limits for VRChat avatars or props?

A: For optimal performance, VRChat recommends keeping avatars under 70,000 polygons.

Q: Do I need to apply transforms before exporting?

A: Yes, always apply location, rotation, and scale in Blender before exporting to ensure correct positioning in VRChat.

Q: Can I use multiple materials on my model?

A: You can, but it’s best to limit the number of materials for performance reasons when importing to VRChat.
