High heels, cute face, all the boys, they want a taste~

Backlace 🎀 is a versatile anime (also called "toon", "cel shaded", or "npr") shader for Unity and VRChat. Backlace is packed with a wide range of features- from anime character shading, to screen-space rim lighting, to procedural glitter. Get started with a single click for a typical fully-lit anime character or dive deep into the advanced settings like Pathing and Refraction! (─‿‿─)♡

This section will be updated when I make things with it! If you make something with Backlace ~ whether a game or shader ~ please let me know so I can add it here! ♡＾▽＾♡

• The official distribution of Backlace itself! You can find it on Gumroad, Jinxxy, Booth.pm, and Payhip (and on this repo).

If you wish to make your own shader with Backlace, please see Contributing to Backlace for more information! This is unnecessary if you just want to use Backlace as-is in your projects (ex. game developers, avatar creators, or world builders). ( *︾▽︾)

Backlace is licensed under the Backlace License (Version 1.5). Please see the LICENSE.md file for the full terms.

For Game Developers, VRChat Creators, and General Users —

• You’re free to use Backlace in any project (personal or commercial) at no cost.
• Please give credit to “Backlace Anime Shader” somewhere in your project, whether that be in your README, credits, or simply in your code. You don't need to be super formal about it or fly a banner, I just enjoy seeing my what my work is used in! (◕‿◕)♡

For Developers Building Off of Backlace —

• You’re free to use Backlace in any project (personal or commercial) at no cost.
• Anything you sell with Backlace must be transformative (adding significant new features or creativity). You can’t just rebrand or resell Backlace as-is.
• You must credit “Backlace” somewhere visible in your shader's user interface (like a credits section or footer) with a link to the official GitHub page.
• Please avoid modifying/redistributing files in the Editor and Processor folders in your project as those are not intended to be built off of. This doesn't apply to anybody using Backlace as-is in their projects.

If you’re unsure whether your use fits the license or just want to talk about it, feel free to reach out! 💗

• This shader was originally a fork of the Toony Standard Rebuild shader by VRLabs, which is under the MIT license. However, essentially all of that code has been replaced, removed, or rewritten. No bugs for Backlace should be reported to them.
• Various lighting modes are derived from other projects, specifically Poiyomi Toon, lilToon/OpenLit, and Mochies Unity Shaders. Thesse are all under the MIT license and code references are limited to lighting modes with those names (ex. "Poi Custom", "OpenLit", "Mochies").
• The "Flatten Model" effect is inspired directly by Lyuma's Waifu2D Shader, which is under the MIT license. Please note Backlace's implementation is simplified and their code is better if a flat model is purely the goal of your project!
• Original inspiration for the Raymarched SSR feature came from orel1's SSR module, which is an implementation of Mochie's fork of ERROR.mdl's SSR. Both are under MIT licenses. While Backlace's idea stemmed from there, the implementation here is much simpler and modified.
• AudioLink features, and a lot of the boilerplate code in Backlace_AudioLink.cginc, are from AudioLink, which is under a modified MIT license.
• Third-party features such as LTCGI and Super Plug Shader are unassociated projects, under their own licenses, and require separate installation.
• Default textures (ex. ramps and noises) are from a variety of sources online, notably Perlin Noise Maker, OpenGameArt, and Booth Matcap Pack 2.
• The name is inspired by a certain vulgar and promiscious angel. (｡♥‿♥｡)
