DGriffin91 / main.rs
Last active July 15, 2023 20:27 — forked from IceSentry/main.rs
Bevy post processing with prepass 0.10
// License: Apache-2.0 / MIT
// Adapted from https://gist.github.com/IceSentry/3949ee344857c2745dc961a64e6fc28f
//! This example shows how to create a custom render pass that runs after the main pass
//! and reads the color texture generated by the main pass, and also the prepass textures.
//!
//! This is a fairly low level example and assumes some familiarity with rendering concepts and wgpu.
