Cesium for UE 5.5 release date

[Rickideee]

Hello,
Just wondering if there is a scheduled Cesium update for UE5.5 which was officially released today?
Thank you.

Hi @Rickideee, welcome to the community!
We released a preview build for UE 5.5 today. See here:

Preview release available for Unreal Engine 5.5

Hi everyone! With Unreal Engine 5.5 just released, we’ve moved quickly to make a build of Cesium for Unreal available for it. You can find the build here: We consider this a preview release, because it’s not as well tested as our usual releases. Let us know if you try it out and run into any problems! Note that you must use the final build of Unreal Engine 5.5.0 that was released today, not the Preview version that was released awhile back.

[Rickideee]

Brilliant!. Thanks Kevin. Love your work!

Hi Kevin ! When I put the Google Photorealistic 3D Tiles, Unreal crashes directly. What should I do?

[Rickideee]

I find that this happens to me as well - UE 5.5 official release version.

[Kevin_Ring]

Are you both on Windows? (it looks like it from the screenshot)
Do you have that problem in the Cesium for Unreal Samples project as well? Or only in your own?
Google Photorealistic 3D Tiles seems to be working fine in UE 5.5 on Windows 11 here, so we’ll have to dig a bit to see what’s going wrong on your systems.

One random theory, a bit of a long shot, is that it’s an MSVC redistributable problem. Can you first try running the executable here:
C:\Program Files\Epic Games\UE_5.5\Engine\Extras\Redist\en-us\UEPrereqSetup_x64.exe

If that doesn’t help, can you try installing the latest version of the MSVC redistributable from Microsoft? You can get it here:
https://aka.ms/vs/17/release/vc_redist.x64.exe

If that does help, it would point to a problem in our build process (it’s compiling with a newer version of MSVC than intended) or perhaps in Epic’s install process (UE 5.5 isn’t installing the redistributable for the version they’ve documented plugins should be built with).

[Kevin_Ring]

Here’s Microsoft’s page with the link to that redistributable, in case that direct link makes you nervous:

Hello Kevin,
Yes I’m on Windows 11 but I also have an issue with the early DASH plugin update - GraphNUnralPlugin.unplugin - which means that I cannot move on from UE5.4 in any case until next week’s DASH fix. I’m also loathe to start fiddling in case Rome burns…

Please keep me in the loop.

Many thanks.

[Rickideee]

For me it was the GraphNUnrealPlugin.
DASH has an update - 1.8.3 for UE5.5 - and I reinstalled Cesium from your file link and all appears roses.
Cesium for Unreal Samples converted to 5.5 and is working perfectly.

Hi I get another crash - right after clicking play - on the tick of the Cesium3DTileset object.

I’m also crashing while opening a level with existing local tilesets. Windows 11, 5.5, recommended MSVC installed

Hi @Nabster, welcome to the community!
Are you using the original 5.5 Preview, or are you using a build out of the pull request with the crash fix? More details of that pull request here:

Preview release available for Unreal Engine 5.5

Hi everyone, we’ve fixed the bug causing the crash when Hardware Ray Tracing is enabled. If you want to try it out, you can grab the latest build from this pull request: Instructions for installing a build from a pull request can be found here:

@Mathias_Lindgren, same question for you. Are you already using the fixed build, and still seeing a crash?

[Mathias_Lindgren]

Hi! sorry for late reply. No, the fixed build solved it for me. thanks!
