# HDRI Skies
If you want to use a sky in your scene, you can do so by using a HDRI sky texture. PFM already ships with a few different HDRI skies, but you can also find plenty for free online, such as on [https://hdri-skies.com/](https://hdri-skies.com/) or [https://hdrihaven.com](https://hdrihaven.com). Custom HDRIs should be extracted to `Pragma/addons/filmmaker/materials/skies/`.
To use a HDRI sky, all you have to do is add a sky actor to your scene. Click the [](https://wiki.pragma-engine.com/uploads/images/gallery/2022-07/pragma-2022-07-17-12-59-15.png)-button in the actor editor and select `New sky`. If the option is not available, you probably already have a sky actor in your scene (only one is allowed).
You can change the sky texture by clicking the `pfm_sky` component of the sky actor and changing the `skyTexture` property. The choice of HDRI texture can have a significant effect on the lighting conditions in your scene when rendering with one of the raytracing renderers. The lighting influence intensity of the sky is controlled through the `strength` property.
HDRI skies *can* be used with the Pragma renderer as well, but in this case they currently only work if the map has a skybox.
##### Sky Orientation
The position of the sky does not matter, but you can change the rotation of the sky with the [](https://wiki.pragma-engine.com/uploads/images/gallery/2022-07/pragma-2022-07-17-13-10-14.png)-tool. This property can also be animated, which you can use to give the impression of moving clouds.
