Hi Josiah, exports from ReCap should work just fine. We used them ourselves in the past and still do from time to time. Make sure on export you use the Complete option when exporting the E57.
After the import, the viewport will be empty, that is normal. You have to press Align to visualize the laser scans in the viewport.
And yes, the viewport will only show a sparse representation of the laser scan, but don’t worry—all the data will be used when you start model reconstruction.

Reconstructed model:
Let me know how it worked out for you with the E57 data.
Have a great day!
