Shared Cubemaps

Cubemaps are shared files used for environment rendering in Foxel. They can be used for Image-Based Lighting, reflections, and background environments.

Accessing Shared Cubemaps

Shared Cubemaps can be accessed through File > Shared Files > Cubemaps.

File Location

Shared Cubemaps are stored in:

Documents\Foxel\Shared\Cubemaps

File Format

Foxel stores Cubemaps in its proprietary .fxlcm format.

This format contains both the environment data and the derived convolution data needed for fast loading and efficient rendering.

Importing Cubemaps

You can import Cubemaps through File > Shared Files > Cubemaps.

Foxel supports several import methods.

Importing Common Cubemap Layouts

Foxel can import many common cubemap image layouts automatically.

🔺 Figure 1: Supported cubemap layouts.

Importing Six Separate Images

You can also import a Cubemap from six individual images.

The filenames must include these suffixes:

• _right
• _left
• _top
• _bottom
• _front
• _back

Example:

• cubemap_right.png
• cubemap_left.png
• cubemap_top.png
• cubemap_bottom.png
• cubemap_front.png
• cubemap_back.png

Note

When importing a Cubemap from six separate images, select only one of the six files. Foxel loads the remaining faces automatically.

Importing 360° Panoramas

Foxel can also generate Cubemaps from 360° panorama images that use equirectangular projection.

Supported Import Formats

File Format	File Extension

Exporting Cubemaps

Shared Cubemaps can be exported through File > Shared Files > Cubemaps.

If one Cubemap is exported, Foxel asks for a filename. If multiple Cubemaps are exported, Foxel asks for a destination folder.

Exported Cubemaps use the horizontal cross layout.
