00. Learning Roadmap

A guide that guides you through the entire book in study order and suggests goal levels/checkpoints/practical problem solving routes

This document guides you through studying this book in what order and with what objectives. It was divided into cases where the focus was “reading the whole thing” and cases where the focus was “solving practical problems.”

To follow along with fast hand movements: 00. 빠른 시작(Quick Start)

Define target level

  • L1 (User): URP settings/materials/default shader modification, use postprocessing

B. Practical Problem Solving Course (“You Need to Implement It Now”)

  • Custom full screen effect (Outline/Edge): 10 → 06
  • Camera color/depth texture required: 05 → 04
  • Not sure where to insert Render Feature/Pass: 03
  • Custom lighting/shadow: 07 → 08
  • Construction of China’s latest subculture style shader pipeline (including deepening): 23 → 28 → 30 → 3134 → 3546 → 47 → 48 → 20 → 24
  • Zhihu/CSDN/Baidu investigation source verification: 27
  • SRP Batcher broken/variable placement problem: 09

Checkpoint (self-check)- Can you explain “when** my pass runs and what textures it reads/writes”?

  • Do you understand “why the additional light loop behaves differently in Forward+”?
  • Have you mapped “which includes provide which global variables/functions in HLSL”?
  • Avoid “code patterns that break SRP Batcher compatibility”?
