Export Settings — Recommended Options

Format: GLB/glTF

Why GLB/glTF is Preferred:

GLB/glTF is the industry standard for real-time applications. It supports PBR materials, animations, compressed file size, and is fully compatible with WebGL, game engines, and VR/AR platforms.

Export Settings

Include

• Selected Objects: Only export what is selected to avoid unnecessary data in the final file.

Transform

• +Y Up: Ensures correct orientation in engines that use Y as the up axis (Unity, WebGL, etc.).

Geometry

• Apply Modifiers: Applies any non-destructive modeling changes.

• UVs: Optimize and ensure proper unwrapping for texture use.

Animation

• Include Animations: Only export the needed animations.

• Do not export all scene actions: Avoid exporting unrelated animation actions. Use NLA strips or organize Actions carefully.

Animation Guidelines

Armatures & Rigging

• Use clean, minimal bone hierarchies.

• Apply transforms before rigging (Ctrl + A).

• Avoid unnecessary constraints or non-deform bones.

NLA Editor — Multiple Animations

• Organize different animations as NLA Tracks: e.g., "Walk", "Run", "Jump".

• Only one Action per model: Each character/object must have a single active action during export.

• All animations in a single GLB file will play simultaneously unless separated during runtime.

Animation Optimization

• Reduce keyframe density using Simplify modifier.

• Bake only essential movements.

• Remove bones with no influence or animation.

Recommended Plugins & Add-ons

• Node Wrangler (comes with Blender): Speeds up shader editing and material creation.

• GoB: Great for back-and-forth workflow with ZBrush (if you’re familiar with ZBrush).

• glTF-Blender-IO: Official exporter for glTF/GLB. Already included in Blender.

Notes

• Whenever you feel your model is too heavy, we recommend using an online GLB viewer and compressor (such as the one from Babylon.js).

• Draco compression can significantly reduce the file size.
