Importing from Visible Human Project crashes Blender:

[MirtoBusico]

Seems that Blender crashes when Bioxel try to import the first image.

I'm using Blender 4.2.0 downloaded from the Blender site. Operating system is Debian Trixie (testing) updated daily Bioxel version is 0.3.3 The image set I'm trying to import is taken from here

https://data.lhncbc.nlm.nih.gov/public/Visible-Human/Male-Images/PNG_format/thorax/index.html

I'm doing something wrong?

Below the blender log and the crash.txt file

[icrdr]

Thank you for the report! From the blender log list info. It seems data was imported successfully. 🤔 So, maybe is was caused by the node... I'll let you know if I figured out

[MirtoBusico]

Thanks

[MirtoBusico]

Hi @icrdr I don't qnow if it can be useful, but here is the system-info file generated with Blender system-info.txt

[MirtoBusico]

Hi @icrdr I tried again with the new 4.2.1 Blender version.

Nothing changes; but I noticed that there is an error message in the import dialog

Any idea?

[MirtoBusico]

Hi @icrdr success!!

Using Blender 4.2.1, ignoring the error and wait five minutes (sorry I don't have a recognized gpu) the loading copletes without erors.

To see something in the wireframe panel I hade to lower the treshold to 32

Thanks
