This could be completely a case of user error, but... When I try to use the Lidar Import node and navigate to a folder with an .e57 point cloud, the file cannot be seen. Even if I change the pattern match to * it refuses to see the file. If I put a .las or .laz file in the same folder, it does see that file.

I also tried forcing Houdini to load the .e57 by manually entering the name, but even though there was no error, nothing actually loaded.

The .e57 and .las files I'm talking about are from the same scan and both will load in CloudCompare without a problem.

To follow up. It seems the loader doesn't like spaces in file names. When I tried loading an e57 file that had no spaces in the name, it showed up and loaded just fine.

Hi Paul, I'm unable to reproduce this with files containing spaces. Which version of Houdini are you using?

Also have you double checked the geometry spreadsheet, centered the viewport, or moved the geometry to the origin? Your lidar data could be far from the origin.
