5.6 Broke Point Clouds Entirely

Development Programming & Scripting

Since updating to Unreal Engine 5.6, it seems the LiDAR Point Cloud plugin is no longer functioning correctly for runtime import/export.

Previously, I was able to successfully use functions like Create Lidar Point Cloud From File and Export Point Cloud to File with various formats such as .las and .laz. After updating, these functions consistently fail.

Has anyone else encountered this issue? Is there a known workaround, or any official word from Epic on whether this functionality is being deprecated or will be fixed in a future patch?

Hey there @X-perto! I can confirm the LiDAR point cloud plugin is broken at the moment. There have been multiple reports on the forums in the last couple hours.

Hi
An ETA for the fix ?

Need we to attend the 5.7 ? (I hope not ^^)

Hey there @Toranis! There’s not currently any projected fix date. I’ll keep an eye on the PR list.

Not at the moment, I submitted a bug report but it’s either been denied or not looked at yet

No resolution for this yet…5.6.1

Yeah the 5.6.1 update does not address this problem.

The plugin seems not to be broken, but missing compatibility with the .e57, .las, and .laz file formats, which were options up until UE 5.5.4. you need to use .PTS, .TXT, or .XYZ to import your point cloud for now. If necessary, you can use a software such as Cloud Compare to convert your point cloud to those formats.

Dumb how that was randomly removed without reason or explanation. I just discovered this moments ago by looking at the available import types available when clicking on import in the content browser. Hope this helps everybody.

Hey there @ForensicRock! Welcome to the community! That’s a great insight. That knowledge could help someone if they wanted to reimplement the compatibility.
