PixelGraph 

PixelGraph is an application for publishing Minecraft resource packs, specially tooled for PBR materials. It allows you to work in a "raw" texture space and automates publishing to one or more encodings, rather than trying to directly encode your textures as design-time. Yaml configuration files can also be used to apply final adjustments to your compiled textures. A cross-platform command-line version is also available, allowing you to completely automating your publishing process from your remote content repository.

• Simplify your workflow by adjusting text instead of pixels. Getting image-based material values just right can be tedious, time consuming, and destructive.

• Preserve Quality by adjusting material values through text rather than altering the original image data. Repeatedly scaling the integer-based channels of your image slowly destroys quality. Save the gradients!

• Support more users by publishing multiple packs with varying quality. The resolution and included textures can be altered using either the command-line or Publishing Profiles to create multiple distributions.

• Automate Normal & AO generation, resizing, and channel-swapping so that you can spend more time designing and less time repeating yourself.

Normal-Map Generation

Allows normal-map textures to be created from height-maps as needed during publishing, or by prerendering them beforehand. Strength, blur, and wrapping can be managed using the textures matching pbr-properties file.

Occlusion-Map Generation

Allows ambient-occlusion textures to be created from height-maps as needed during publishing, or by prerendering them beforehand. Quality, Z-scale, step-count, and wrapping can be managed using the materials properties.

Installation

For manual installation, download the latest standalone executable from the Releases page. For automated usage see Docker Usage. Visit the wiki for more information.

Manual Usage

A single Pack-Input file lives in the root of the workspace (~/input.yml) which specifies the default formatting of all content. The example below uses a 'raw' encoding which manages each channel in a different texture; The 'height' channel has been set to inverted.

# ~/input.yml
format: raw
height:
  invert: true

One or more Pack-Profiles are used to describe a publishing routine; they also live in the project root and should match the naming convention ~/<name>.pack.yml. Each profile can specify pack details, encoding, format, resizing, etc; this allows a single set of content to be published for multiple resolutions and encodings, ie pbr-lab1.3-64x or default-128x

# ~/pbr-lab13-x64.yml
output:
  format: default
texture-scale: 0.5

Material files are used to desribe a collection of textures that compose a single game "item". For more details, see the Wiki.

# ~/assets/minecraft/textures/block/lantern.pbr.yml
smooth:
  scale: 1.2
metal:
  scale: 0.8
emissive:
  scale: 0.2

Sample Repository

Oversized - A high-resolution texture pack made primarily using stock textures and CTM.

Textureless - A low-resolution pack using solid colors, material values, and alpha-masking to provide a smooth visual base for shader testing. Also good for toon/outline style.
