Volumetric Skyboxes

Have you ever found regular panoramic Cybergrind skyboxes a bit boring? What if you could have entire scenes unfold in the background? Or maybe you just want a nice rain effect on your Cybergrind arena?

Basic usage

In the blue Cybergrind terminal, open Themes -> Custom -> Skybox. You'll notice two extra buttons at the bottom of the screen.

Volumetric skybox files are located at ULTRAKILL/Cybergrind/VolumetricSkyboxes. This directory will be automatically created containing the default skyboxes the first time you launch the game with the mod installed. All the custom volumetric skyboxes must also be placed inside this directory.

Browser

The first one leads to the volumetric skyboxes browser. To close it and get back to the conventional skyboxes menu, just press it again.

N.B.! You can enable several skyboxes at once. It's a deliberate design choice to allow effect-focused skyboxes to remain enabled while another skybox is active. If multiple skyboxes have a custom fog / lighting scheme / grid textures at the same time the resulting visuals may be unpredictable.

Settings

While not all skyboxes can do this, some can override ambient lighting, grid textures and regular panoramic skyboxes. This panel controls which features skyboxes are allowed to override.

As a bonus, even if you don't have any skybox enabled you can still tweak the lighting on Cybergrind arena.

Installing custom volumetric skyboxes

As mentioned before, volumetric skyboxes are stored at ULTRAKILL/Cybergrind/VolumetricSkyboxes. Place your .cgvsb file there and restart ULTRAKILL for the mod to pick up all the changes.

VERY Important note: Volumetric skyboxes are basically Unity prefabs. They may contain sounds, flashing visuals and, most importantly, can utilize some native ULTRAKILL logic.

Even though custom scripts are not supported due to security concerns and custom skyboxes cannot directly harm you, I advise you to remain careful with the skyboxes you install.

Creating your own volumetric skyboxes

It wouldn't be much fun if a handful of default skyboxes was all you were getting. Install the editor, make your own and share them with others.

The editor itself is something akin to the Rude editor (hell, 50% of its codebase comes from the Rude editor) and can work within a Rude project.
