**If importing a lidar point cloud via Python, how can we automatically set the color range, and columns without having to manually fill out the import dialogue each time?**

```
import unreal
AssetTools = unreal.AssetToolsHelpers.get_asset_tools()
AssetImportTask = unreal.AssetImportTask()
AssetImportTask.set_editor_property('filename', "d:\test.xyz")
...
AssetTools.import_asset_tasks([AssetImportTask])

```

**Also if we set AssetImportTask.automated = True, then Unreal returns a Python call stack dump. How can we get around that?**

```
