Loosing surface in level set when decreasing voxel size

[Jaisiero]

Hi guys,
I was playing with openVDB and testing with some input params using the meshToLevelSet method.

When I tried to increase the resolution to certain level by decreasing voxel size, I find out that I cannot see the SDF (surface) anymore on the vdb_view app.

Both volumes has 3.0f as a narrow band.

I can attach some images so you can compare. I also copy links to the vdb files that I generated in case you need'em.

Am I doing something wrong, or there is a certain limit due to number precision, or something else that I am missing?

Cheers!

Hi @Jaisiero,

Can you provide the input mesh you were using to test?
