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

This tech demo 100% did, that was not a lie. But its important to remember this was a tech demo, not the full game which is still being worked on. We are just as excited as everyone else to dig into the full game once it launches!

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 :)

Hey, We have so many bugs fixed in 5.6, so probably the best thing you can do is test your issues there (by compiling source from Github) and report to us if still broken. You can also engage with the community on the #ai channel on the Unreal Source Discord. I try to frequent discussions there.

I just started playing Assassins Creed: Shadows, and really enjoying it! Weird how that "internet rage" often feels disconnected from reality.

Ah yeah forgot about that :) I remember now filing two separate tax returns the short time I lived in the US.

Fellow migraine sufferer here, I hope you feel better soon! Have you been to a specialist and gotten medicine? Getting a prescription for sumatriptan changed my life. Now I have an injection pen and usually migraine is gone in 10-15 minutes.

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 :/

Sometimes I feel like my views are radical... Its simple, be kind and treat everyone equally. But I must admit my tolerance for hate is low.

ugh, I know your pain. For a while I had to self-inject for B12, and I so did not like that. I dont mind others injecting me, but injecting myself or others is .. not pleasant.

Iirc they are mentioned in Mikko’s talk from Unreal Fest. Dont think its in the docs yet beyond a quick description in 5.5 release notes.

Improved debugger also coming in 5.6, you can preview the work in progress on github if you want.

5.5 added property binding functions, and with that you can get the actor from the context and fetch anything you want.

Stay tuned, LOTS of improvements coming on tick optimizations in 5.6!

Sigurdur Gunnarsson @siggigg.bsky.social · 14/01/2025
There is no way to automatically convert them no :) State Tree requires a bit more structured thinking, which I know in some cases can be friction for some teams. If you ever revisit State Tree, I'd love to hear your thoughts. We have some more documentation and guides on it now as well.

Sigurdur Gunnarsson @siggigg.bsky.social · 14/01/2025
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.
