@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

Hehe I’ll get right on that

here’s the hip. it’s pretty basic and not even technically a solver. It’s a surfacedist lookup from all points to a source group of points (the black rectangle in the beginning). Then I’m animating the visualization range of the distance value. Increase the grid density / decrease the mountain element size for more tendrils. If there’s a way to speedup that surface calculation, this should run even faster.

rect should be set to something like how big a part of the stamp ends up within one pixel of the outputted image.

that is a bit of a pita to calculate.

regarding the color picker. if i do an inspect in the viewport the unbelievable bastard has the correct values right there… FRUSTRAPOINTED

can i get those values? no, course not, they are just there to taunt me.
