Point cloud rendering with Android

Development Platform & Builds Mobile

Hello,

I’m trying to create a simple 3D viewer for my point cloud files (apartments, buildings etc.) to an Android phone.

Whenever I try to launch it through my device, it doesn’t render anything on the screen. (UI works).
Also in Editor, when launched in “Mobile preview” or setting the Viewport to “Android ES 3.1” Rendering mode, Unreal crashes with following error message:

Fatal Error [File:/Build/++UE4+Licensee/Sync/Engine/Source/Runtime/Engine/Private/Materials/MaterialShared.cpp] [Line: 2049] Fatal Error Material not found

It seems like Android is somehow unable to render point cloud data as it is. Is there a way to convert it?

  • I’m using UE 4.25 with LiDAR Point Cloud Plugin (Built in version) and the latest Android SDK and NDK.

  • Other than Point Cloud Android builds works fine

  • Point Clouds are .las files

I really can’t find anything related to this anywhere.

Thank you in advance.

I have the same question with one small difference: I’m trying to run the android app on the Oculus Quest and it doesn’t crash if I add the lidar data to the project.
In desktop VR it works as intended.
