Creating Volume Textures

Before you can use Volume Textures in your Unreal Engine 4 (UE4) project, you will need to enable them. In the following How-To, we will take a look at setting up your UE4 project to use Volume Textures.

Steps

  1. First, make sure that the Editor is closed, and then locate your project's DefaultEngine.ini file and open it.

  2. Locate the Script/Engine.RendererSettings section and add the following variable, then save the file when you have added it:

    r.AllowVolumeTextureAssetCreation=1
  3. Re-launch the Editor, and in the Content Browser, locate a Texture that needs to be made into a Volume Texture.

End Result

With the Volume Texture now created, double-click it to view it in the Texture Editor. To see how the Volume Texture will look in 3D, hold down your left mouse button and move the mouse around in the Texture Editor. This will rotate the Volume Texture so you can see it from different points of view, like in the following video:
