# Creating custom lights/sirens

## Warning:

If you have never made any props, don't know how to stream custom props, or how to use Blender. 

Please learn that first if you want to create a custom light/siren. We will not be able to assist you with basic Blender/Sollumz questions. This guide covers everything necessary to create a custom light for our script. It will not teach you how to use Blender or Sollumz

### What's needed?

To create a new animated light prop for our kq\_emergency resource. You will need [Blender ](https://www.blender.org/)with the [Sollumz ](https://github.com/Sollumz/Sollumz)plugin. If you have not used Blender, or Sollumz before, I highly encourage you to try learning those individually first, as this is not a simple process if you don't know those environments.

### How do the props work?

The sirens/lights are simple props, with emissive materials and (in some cases) lights. The props default state is a disabled state, so no visible emissive materials. 

The prop will have one animation, which will be its "ON" state. 

### We highly recommend starting using our example project

Download the example project and open it using Blender. Make sure to have the newest version of Sollumz installed

### Editing the model

Modify the model of the prop. That's the `kq_police_led_model` mesh element. To modify the emissive elements you'll need to modify the `kq_police_led_emiss_blue` or `kq_police_led_emiss_red` mesh elements.&#x20;

Check the rest position of the bones. In Object mode select the object, and in the pose tab press on the "Rest Position"

To check the animation select the "Pose Position" within the same tab

Open the timeline and drag between 0-30 frames and 30-60 frames to see the animation change. Obviously you can fully edit the animation. If you don't know how Blender/Sollumz animations work, I highly recommend checking out this tutorial by ook\_3d (<https://www.youtube.com/watch?v=dfO1eQf8WE0>)

### Saving the model

Make sure to rename the animation and the prop and create its archetype definition.&#x20;

Export the prop and the animation, and stream both as usual
