For my holiday break project I’ve been sketching out an idea to help soften the on-ramp for beginners learning D3D12: a header file that (very lightly) wraps the D3D12 API and only exposes the latest/most-useful bits through straightforward function definitions with ImGui-style inline documentation.

The post on using spatial hashing with raytraced ambient occlusion attracted quite a bit of interest so I expanded it into a blog post to discuss how it works behind the scenes to both reduce the noise and its cost. interplayoflight.wordpress.com/2025/11/23/s...

I finally found the time and energy to make a new blog and write a couple of posts. This time I wrote about PBR content and game development principles. Both posts are quite different so hopefully people find something interesting on either one of them.

And with that last thread ended, I'm so excited to share that tomorrow is my first day at Digital Extremes!
After the project cancellation I finally had the chance to pop open Soulframe after getting access a long time ago, and I got hooked so quickly that I jumped at their job page.

Sharing some details about my job hunt in case it's helpful to someone!
After our project got canned I applied to 12 jobs as a first, and mercifully last, batch.
6 were Unreal-based, 6 were custom tech
