Our games industry is people. Our studios are people. Our teams people, our games by people for people. Our games are made by people, in groups of people, in teams of people, making people things for people. The magic is people, and the people deserve so much better than all this. I am so sorry.

Well, today’s the big day! Moving to Stockholm, Sweden :) Living in 5 different countries is my limit, so hopefully this is the last one.

Almost 10 years ago I made a little example on Github to learn mesh generation in Unreal and play with procedural and fractal algorithms. I just upgraded the project to Unreal 5, fixed a bunch of issues, and added a new mesh type that looks more like a proper tree :) github.com/SiggiG/Proce...

Even though its not a genre I usually enjoy, I decided to give Clair Obscur: Expedition 33 a go, and I'm glad I did! One of the most unique games I've played, probably one of my top 10 favorites. This is going to win all the awards this year :) #GOTY

Its been a while since a game 100% hooked me from the start, but Kingdom Come Deliverance 2 has definitely done so! World building, story, characters and systems are all amazing here and I look forward to really dive in for the next 100? hours or so :)

Its been a difficult game to get into, but I'm really enjoying Warframe these days! Good alternative to Destiny 2, which sadly is a shadow of what that game used to be :/

Those of you still using Behavior Trees in Unreal, are there reasons why you havent switched over to using State Tree? Im genuinely interested to hear, and what we can do to improve the tool.

My reaction when a new NVidia GPU is announced: "Wow those are some huge gains!" My reaction when a new CPU is announced: "Meh" Why is the CPU industry not on the same incremental growth curve? Is it a lack of a driver/need?

What do you all consider the ideal approach to author AI behaviors? Freeform graphs spaghetti? A more structured hierarchical fsm? Utility scoring? Something else? Consider ease of authoring, flexibility and ease of maintaining (thats where normal behavior trees fail IMO).

5.5 added the console variable “tick.AllowBatchedTicks” which will automatically group together simple tick functions. It gives a bit of a boost to tick heavy projects but I'm keen to hear results from anyone that's enabled it and seen what happens! Anyone tinkered with 5.5 yet with info? #UETips

One of the breakthrough hits for me this year is a German game called Enshrouded, and they just realeased a massive new update. They have their own custom engine and voxel world, and its mighty impressive! Probably the best visualization of voxels I've seen, being able to add detail dynamically. 🧵
