# Custom Asset Preparation

Simulon supports .glb, .usdz and native .blend assets. In most cases, you will get the most control and expected upload results when using Blender to prepare your assets. As such, we recommend using Blender where possible to prep your assets. The Simulon Asset Preparation plugin simplifies certain processes when working with Blender to avoid common mistakes when creating assets for Simulon through Blender.

**Note**

The only limit for what you can put into a .blend file is the poly count which is currently fixed to 2 million triangles.
