@.goldfarb. What do you mean __can’t__ select?! ||the quirk is that you need to have a selection already started||

Oh, if auto is enabled there is no need to press the button to commit the selection

opnode_sum.py

“` This script will inspect all installed operators in houdini and create a table summarizing them.
hython opnode_sum.py > nodeinfo.json
The -p option will also output the parameter information. The –briefparms option will output name/label parameter information. “`

@tokyomegaplex ?

a bit of this and that :

Tested with that FBX that has embedded textures … at some point as folder “`Gas Station.fbm“` was created but I don’t by who, probably the fbx_archive_import … after that you can use a “attribfromparm” that helps to create a dict from nodes parameters, and retrieve the path to every texture plug as basecolor_texture.

It’s possible you don’t even need a loop for this, but it’s easier to build and check strings that way.

if you want to sample points at the medial axis you could look at something like `coverage axis ++` which uses some really simple metrics to sample points at the medial axis without needing to do any kind of fusing/remeshing or advection.
But i will say the medial axis is inherently not as useful as the straight skeleton, cuz in 3d for many shapes its a surface and not a curve…

arxiv.org/abs/2401.12946 its a neat paper, a totally different approach for finding these surfaces. @mattiasmalmer @_white_dog_

if you want to get topology out of this and not just a point cloud it definitely takes more effort, and no one likes using effort
