Problems when opening a obj with edited global shift and scale

Post by oeysteindigre »

Hi, and thanks for this amazing software!
I have a issue when saving a obj with edited global shift and scale.
When opening the saved obj file in common viewers, the modell is damaged.
Any idea how to avoid this problem?

If you open the file again in CloudCompare, is the model damaged, or does it still look ok?

Because I wonder if the other tool is properly managing large coordinates? (OpenGL for instance doesn't like large coordinates, and it creates rendering issues due to the truncated coordinates).

Thanks for answering Daniel.
It’s looking good in CC. Also in agisoft.
In windows 3d-viewer and meshlab it’s not.
Is it possible to not save as large coordinates, or you know other workarounds?

It worked well when turning of the “preserve global shift on save” function :)

Ah yes, or you can also use later the 'Edit > Edit Global Shift & Scale' option (to set the Global Shift to (0, 0, 0)).
