Enemy System Progress + Player/Camera Integration
Solo Game Dev Vlog In this vlog I walk through the progress I’ve made on the modular Enemy System (attack and spawn) and the first phase of Player & Camera Integration . The enemy system now has a solid foundation: data stored in ScriptableObjects, health and attack modules, movement patterns like chasers and ranged units, and loot drops tied directly into death events. I also built a spawning system that uses NavMesh sampling to keep things flexible and reliable. On the pla

Comprehensive Cheatsheet on Unity 2024/2025. CG Shader Operations & ShaderLab
by Pavel Zosim · v1.3 1. Introduction This post outlines core principles and practical tips for writing CG shaders in Unity. Whether you’re transitioning from ShaderGraph or diving into hand-written shaders, this guide provides you with an in-depth look at shader code structure , property declaration, and how the GPU processes shader code. We’ll also explore special ShaderLab features such as drawer attributes, tags, and SubShaders, and discuss how these concepts vary across

Shader Fundamentals in Unity/Unreal
edit v.0.6 Shader Fundamentals and Rendering Pipeline Shaders are small programs (with a “.shader” extension in Unity, and .usf/.ush in Unreal) that determine how surfaces interact with light . They perform mathematical calculations and execute a set of instructions (commands) to compute the color of every pixel covering an object . In essence, a shader tells the GPU—whose thousands of small, efficient cores are optimized for parallel processing—how to render objects based

Compute Shaders in Unity.
Compute Shaders are specialized tools that enable massively parallel computations on the GPU, bypassing the traditional rendering pipeline. They’re ideal for tasks like real-time texture generation, physics simulations, and complex data processing.

FX Breakdown: Flame Simulation - Vertex Animation (Houdini / Unreal / Unity)
In this short video, I present a quick overview of the "Camp Fire" FX creation process using Vertex Animation techniques. I used Houdini 20.5 with Sparse Fire Simulation and upres techniques for Unreal Engine 5.4 with Lumen and Unity URP/HDRP 2022.3.4. Watch as I showcase key steps, including geometry preparation, loop animation, shader creation, and particle system building for sparks, hot air convection, and burnout sticks.
