Missing part on 3D plot

[GiudiceVitor]

I am plotting 3d cubes. Most work fine, but I have found some weird artifacts on some, like this one:

Notice we have a missing part on the cube. I checked, and this is not a problem on the data (there are not NaN values, nor 0s). When plotting a single slice of this cube on matplotlib, we get:

Notice the black part near y=40 is the missing part on the k3d plot. It's just a part with lower values (close to -0.4) with the exact same value all along.

What would that interaction with k3d be?

Hi @GiudiceVitor Can you tell me what k3d object it is. k3d.voxels?

[GiudiceVitor]

It is a k3d.volume

@GiudiceVitor can you share data with me? [email protected]

I'm afraid I cannot :'(
It is sensitive data
and tbh I don't recall specifically what data point that was. Sorry.
I don't know If this will be too difficult to reproduce, because it is not very common, from my experiment with k3d (happened only with one or two data points only)
