Creality Scan keeps crashing on creating Mesh

Why does Creality Scan software keep crashing on attempting to create the mesh?

The error message is very generic, and pops up almost instantly on some scans when I try to create the mesh. It’s not happening on all scans, only some. I’ve only used the software for a few hours so I haven’t noticed any pattern yet. But when a scan refuses to mesh, it always refuses to mesh. I can quit and restart, and try to create the mesh - but that project will always crash immediately with the same error.

Could it be connected to the size of the point cloud? are there memory settings anywhere I can increase?

I was using the maximum 0.02mm resolution on the Optimisation settings before meshing, when I reduced the resolution to 0.05mm meshing worked.

Note my PC is a Unit - 128gb memory, RTX 4090, and 16 core Ryzen 5950 - so it’s certainly not resource constrained.

The same thing is happening to me today :frowning:

If you scan an object as large as a DSLR camera, the resolution of 0.05 is the operating limit, and the smoother should be 0.1.

Same error here.

Is there a limit of cloudpoint number the software can handle to create the mesh?

Here are the last lines of the logfile

From where did you take that? How can you be sure the max resolution for a not large object as a DSLR camera is 0.05 and smoother 0.1?

I’m fancing the same problem here, looks if I capture too much details the software crashes even with lots of resources (CPU/RAM/Disk) available.
