Background
The background feature allows you to set a background image or color for the performance.
Default
The default background is a dark checkerboard pattern, which provides a neutral backdrop for the performance. It has no configuration options.
Background image
Desktop only
Image backgrounds use cubemaps. A cubemap is a set of six images that map to each face of a cube. The app displays the images on the inside of the cube, creating a 3D environment around the performance.
You can use any image as a cubemap, but it works best with images that are designed for this purpose, such as panoramic images or skyboxes.
You can find free cubemaps online, or create your own using a 3D modeling software.
To set up a cubemap, select Cube map as the background type. A card showing the six sides of the cube appears: north, east, south, west, up, and down.
- Drop an image onto a side, or click a side to choose an image for it.
- To use the same image on every side, click Use one image for all sides.
- To clear a side, click the button on it.
Images you choose are copied to the ~/.midis2jam2/backgrounds directory.
When you choose an image for a side, you can pick from the images you've already imported.
Click Open textures folder to open this directory.
Important
Images for use in a cubemap must be square, all have the same resolution and format, and all must either be RGB or RGBA.
Images can be in JPEG, PNG, BMP, or GIF format.
If any side has no image, or an image can no longer be found, the app warns you before the performance starts. Click Open background settings to fix it, or Play with default background to continue with the default background.
Background color
You can set a solid color as the background for the performance. You can choose any color using the color picker.
