I discovered the workflow of how to convert a fbx model into a LiDAR point cloud in UE5
- Embed texture on model: prepare fbx/obj model, drag it into maya/blender, link the texture image, export the fbx with “embed media” selected.
- Convert the format into LAS in Cloud Compare: drag the fbx into Cloud Compare, edit>mesh>sample cloud, then select the point cloud, go to file> save, to export the LAS format.( you may need to go edit>apply transformation>Euler Angle to change the x-axis rotation 90 degrees before export, because the axis mode is different in UE5)
3. Import the lidar point cloud in UE5: Go to plugin> tick lidar, restart, then drag the LAS format file in content drawer.
