Here's an easter egg in the new Lego Batman that I think all of you will REALLY appreciate. It's so good, I had to make a video.

My favourite thing I heard of like this is a debugging feature in Alien Isolation where instead of hissing the Alien states aloud what it's thinking about. "I heard you. I am hunting you. I am hunting you. I am hunting you. I have found you."

The morphs in Keeper use distance fields as an (implicit) surface representation, which makes it possible to control the distance at which the surface should lie. In other words, it’s easy to deflate or inflate objects, and meshes become easily ‘moldable’.

Made it to Ultimate Vault Hunter level 5 in #Borderlands4, the first time I've ever reached max endgame in a Borderlands title. Maybe now I'll get back to the other games on my backlog.

Fun with spooky lighting for #screenshotsaturday. Fun fact: I made a component that causes any actor -- like this lighting rig -- to follow the viewport camera. No need to fiddle with un/possessing or piloting an actor. :) #unrealengine #procgen #usability #dungeoncrawler

This is a pretty big hobby milestone for me-- a real corridor & chamber solution that works with PCG partitions. Now I can experiment with more interesting generators for the corridors and chambers themselves, and interior/exterior features. #PCGEx #procgen #UnrealEngine #dungeoncrawler

Rolled credits on #Borderlands4 last night. Gearbox built a super impressive, layered open world and filled it with lots of fun things to see and do. It’s a rock solid platform on which they can build DLC and maybe even new features.

💡 Today's insight: "timberpunk." I don't know why this didn't occur to me earlier but it captures in one word much of the #Thief adjacent aesthetic I've had in my head for my dungeon crawling game. And it gets #ChatGPT closer to my target than anything else I've tried.
