I can’t create this project it says not compatible with unreal engine 5.6

I also tried to convert an existing City Sample 5.54 project to 5.6 and it failed.
They did use City Sample to showcase their “Fast Geometry Streaming Plugin” (1), so let’s hope they will update the City Sample project (along the separate “city sample crowds” + “city sample vehicles”) soon to allow us to get it working on 5.6.

likely will need to wait a bit for them to update it to 5.6
It took a while for them to update 5.5

Or if you are impatient you can try manually compiling the plugins that it uses, but some are pretty dense with C++ templates and ECS logic so might be worth just waiting if you have a lot of compile errors

Indeed, IIRC they only updated it to 5.5 a few months ago (let’s hope this will be quicker this time around).

I’m bumping this up. I’m also waiting for the CS to be available for 5.6. as I’m using a lot of it’s systems in my project and don’t want to mess with the plugins myself.

It’s not the real CitySample but just a modified Traffic plugin, if you are only interested in the code changes in MassTraffic.

Hello. The date is 8th Oct, 2025.

I upgraded my PC, so now it’s:

AMD Ryzen 7600 3.6GHz 6 Cores

32GB RAM running at 4200MITs

MSI RX 6600

512GB SSD

Once opened I found I had to disable Ray Traced Refractions. Turning this off increases the FPS by 10. I’m seeing about 70FPS and as the shaders load as I move the character around drops to 30FPS, but once that’s out the way it returns to 70FPS. I think 60FPS is a good target. I don’t see mirror reflections in the car windows no matter what settings I use, but my GPU is a lower end card. With the default settings (minus refractions), I like the look of it and can walk around and enjoy the mighty demo in action. I see the benches might have been set up to allow the character to sit on them, but this isn’t possible. The metal benches do look brand new and could have looked aged. The signs are also a bit blurry. Buildings could look better and the MetaHumans could look better. I think this is my GPU and RAM that lets it down. The floors do seem photorealistic. I couldn’t get the night mode to work properly, so maybe I need to turn on the material settings which can be found in the docs? Lumen works great with GI and Reflections. I would have liked the Photo Mode to save an image to my SSD. The project doesn’t take long to initialise, but the demo needs time to load and compile shaders (maybe 20-30 min) when I hit play. Once that is over and part of the city World Partition is loaded, I can jump in the game within 10 seconds.

My PC cost me around £600-700 and I built it up over a few months.
