No, please use this option to upload it:

Thank you!

I can’t upload txt file.
I uploaded it to pcloud.
here is the link:

Thanks you!!!

Hi @jonydaar,

Why do not you upload the *.log file that has been generated during the processing?
Menu-Process-Open-Results-Folder

It contains many information that are useful for us that are not shown in the sample you sent.

Thanks,
Best

The website not allow to upload txt file. I uploaded it to the cloud and posted the download link.

Hi @jonydaar,

You are right. Adding files was block for new users.
By now it should be okay. I am very sorry for the inconvenience.
Now you can add your files.

F13-16 short.log (3.9 MB)

Same issue, how about this log file?
Full Log file is ~29,046KB max upload size is ~4KB. If you need the full file, please provide an alternate upload option.

Hi @David_Pechacek,

No, it’s OK. We don’t need the full log. We found all information we need in it.

Could you please do a test and slightly reduce the RAM cores and run Step 3 again?

Afterwards, please respond with an update.

Thanks!

Beata,

That’s actually what I had done already. But I am on a new PC now, so cannot retest at the moment.

We did get what was needed (point cloud) the ortho was just a bonus.

Thanks,

Hi David,

OK, thank you for the information.

So I will add just a note. The second step to solve this problem would be unselecting the Merge Tiles option and verifying if the process finishes successfully. If yes, that would indicate an issue with RAM.

Dear Beata, same problem happens with us and for that please see our logs. kindly share email id for logs as our projects log crosses 4MB

Hi @himalay24sharma,
