# How Marso Studio Works

{% hint style="info" %}
This is the very first release of Marso Studio, expect bugs and errors - you are in the first 500 users. Your feedback in greatly appreciated
{% endhint %}

### How Marso Studio Works

Marso Studio takes a 3D asset (as a.glbfile) containing a mesh and its base colour texture, runs it through our I2M model, and outputs a PBR texture pack:

* Albedo — refined base colour
* Roughness — surface micro-detail
* IOR (Index of Refraction) — dielectric reflectivity
* Metallic — conductor vs. insulator classification

The model predicts these maps from the base texture and applies them back onto the mesh. You're adding PBR to an existing asset — not fixing the asset itself.

#### Normal Maps

You can toggle on Show Normal Map in the 3D viewer within Marso Studio.\
Please note: this does not affect the generated PBR output, only the render within the viewer.

{% hint style="success" %}
Our I2M model can also produce specular and diffuse maps. Web viewers are unable to support this, so they will only be available via the I2M API.
