# 3D models

LightAct supports **.fbx** and **.obj** 3D formats and to an extent .dae.

{% hint style="info" %}
**Good to know:** FBX is the preferred format and the one that has the best support.
{% endhint %}

If you want to apply content on a 3D model, you need to properly UV map it and make sure that the normals are facing the correct way.

## Render mode

By default LightAct uses **Shaded Render mode**, as it is the most appropriate for general visualisation in the Viewport.

{% hint style="warning" %}
If the 3D model is a Source for a projector, always use **Unshaded** render mode. Otherwise the content won't look as intended.
