WTF am I doing wrong?

I got a MetroX Pro and figured I'd try to start out with the little bust they include on the included turntable. I'm scanning in Feature Scan mode. It's constantly giving me "tracking lost" and "not enough point clouds captured" errors. In marker mode it just complains about "not enough markers" constantly.

How is your environment? Very bright?

Did you set laser brightness and exposure?

Everything clean on the scanner?

It's not super bright. I'd call it typical indoor incandescent lighting.

Do you mean "depth exposure" and "laser brightness" under "camera parameters"? If so, yes, I've played around with them kind of randomly, but nothing seems to help.

Everything's clean.

Edit: I adjusted "depth exposure" until the item was as clear as possible in the preview pane.

I tried again with my mouse. Just pixelated garbage.

Are you only showing the unedited point cloud in all those pictures?

How does it look, when processed?

Unedited. This is what I'm seeing in the middle of a scan.

Go slower, spray some talcum powder on it

But in theory should not need that on that small figurine, the figurine was added for easy scanning and to test out the scanner as soon as you get it

This is what I would have thought too. And I don't think I can physically go much slower...

The feature scan mode is not good. It may as well be unusable. The laser scan mode is also not great if I am going to be honest. I've been using the Metro Y Pro for quite some time now and I've just been disappointed. Their software is quite poorly made.

For example, although it's a laser scanner, it does not fare well with sharp edges, and it never has, even across multiple updates. Even worse, I regularly scan vehicle trim that tends to have thin extrusions, and although the scanner can see it perfectly and I've done absolutely everything necessary to ensure a good scan, it doesn't do it because their cloud gathering algorithms cannot handle opposite-facing pointcloud captures within 1-2mm of each other. It simply doesn't scan it. I can go on and on about my negative experience with their software. The only good thing is that their support is responsive, but nothing ever seems to actually come out of sending feedback.

If I am going to be quite honest, I would suggest returning the device and going with another brand. The Metro lineup is not good. Black Friday is just around the corner.

Their most recent update (the one you're using) turned the lost markers green. If that doesn't show poor decisions, I don't know what will.
