Themes

Everyone loves different dice colors and styles. Also, sometimes it's important to have different colored dice at the virtual table in order to distinguish who's making rolls. With that in mind I've tried to keep the theme layer flexible and easy to customize.

How themes work

Themes should be located in the /public/assets/dice-box/themes folder. Dice-Box only comes with the default theme. Additional themes can be downloaded or installed from @3d-dice/dice-themes. Themes have been designed to be easy drop-in addons. Inside a theme folder is a package.json file used by npm, a theme.config.json file, a couple of texture files, and possibly a json file for the 3D models used by this theme.

The folder name for a theme must match the systemName parameter in the theme.config.json file.

Using NPM

If you use npm to install a theme, then you must manually copy the theme to your static assets folder.

It's important to know that Dice-Box currently only loads the StandardMaterial and CustomMaterial libraries from BabylonJS. PBRPhysics-Based Rendering - is a virtual material pipeline that can simulate any kind of physical material. materials are not currently supported due to the high overhead it has. It's also important to know that BabylonJS expects normal maps to be DirectX formatted. If you have OpenGL normal maps then you'll want to invert the red and green color channels of the file (using image editing software like Affinity Photo) to convert it to DirectX.

For distribution reasons, themes from @3d-dice/dice-themes include their required 3D models, but if you're using multiple themes that load the same model file, then you can put that shared file in the /public/assets/dice-box/models folder. After that, update the meshFile path in the theme.config.json files as necessary. For example

  meshName: "gemstone",
  meshFile: "../../models/gemstone.json",

How to make a custom theme

If you want to make your own textures today then there are two approaches possible.

1. The first approach is to duplicate any standard material theme folder and use image editing software like Affinity Photo to skew the colors or make changes as best you can. Also available are the .png files in the default theme if you need to reapply the dice numbers over top of any color changes you make. Once done, update the theme.config.json file as necessary. You could even point the bumpTexture and meshFile paths back to the original theme if you don't want to duplicate them.

2. The second approach is to bake your own textures using the original 3D models. This is the only way to create new seamless textures. Start by downloading the 3D dice I've used for this application available here. Once you have the .blend files, you can open them in Blender to bake your own procedural textures. There are a couple of youtube videos available that demonstrate how this can be done.
