PSO Caching Update: UE5

Let's begin by saying that I didn't really intend this to be a two – or maybe more – part series on this blog. I'd wanted to create a plugin that took the pain out of PSO collection and precompilation and put it on the Epic Store, but that probably won't happen.

PCG Assembly Script in Unreal 5.2

The Procedural Content Generation (PCG) framework is experimental in Unreal 5.2 and using Packed Level Actors assemblies isn't well-documented.

Current Lumen Mirror Reflections on Pascal

Originally, I was going to explain the effect in the header image. I even had a part about the requirements I had for this small scene, but instead, I'm interested in the Lumen reflections here. These comparisons are from Unreal 5.0.3 running on a pre-raytracing-hardware GPU, so take

AV1 Video Transcoding

AV1 is a relatively recent video codec build by the Alliance for Open Media (AOM) [https://aomedia.org/]. It provides a encoder that beats H264 in file size for a given quality, and is significantly less patent encumbered than H265 – H264's successor. For completeness, AV1 competes quite favourably against H265

Viewpoint – Camera Perspectives

Choosing a perspective is truly an endeavour that must be analysed on a case-by-case basis. There is both an element of lining up the benefits of each techniques and intent of the team.

PSO Caching in Unreal Engine

Pipeline State Object (PSO) caching in Unreal Engine 5 for Windows (DirectX 12 SM5/6) and Linux (Vulkan SM5). PSO caching enables developer control over shader precompilation and reduces stutter linked to just-in-time shader compilation.

CICD in Unreal with Jenkins

Continuous Integration/Continuous Deployment is a cornerstone of modern software engineering methodology. In short, the goal is to always have recent builds of the software available to test against. These builds are automated and the build system runs a series of automated tests run against them after a successful build.

Unreal Engine 5 – Nanite and Water

Nanite in Unreal Engine 5 enables far greater geometry density. When using this awesome technology for floor geometry, some of the older techniques for achieving visual effects no longer work. A prime example of this is the use of water puddle shaders. When using normals to fake geometry, layering puddles

Interactive dialogue is a powerful system with an excellent scope, but from a development perspective, building one is a costly endeavour.

Tips and Tricks – Hashing

Hashing is a common occurrence in digital applications, whether it be for keeping passwords safe or for digital signatures, but what type of algorithm should you use and why?
