Hello,

I would like to know if there's a way to save points to a file with Houdini?

Thank you

Simplest way to do that is to right click on the node, save, geometry. You could also use a file sop node.

Yeah but my goal is to export the coordinates of all points to a file (text or json or whatever…). Is it possible in a simple way or through a script?

ah, it was not clear.


One way is to use csvoutput TOP node, see example file
I guess there are other ways too, without using pdg tech..

Sorry, but I'm new to Houdini… How exactly do you get the node to create the file?

dive into the topnet, select csvoutput node, set the filepath and right click on the node, ‘dirty and cook’ selected node

the example file is already setup to write to csv the point positions of the grid object input of the topnet

So, I've managed to extract the points of the grid from your example. But, my main goal is to exctract coordinates from a scatter into a file. When I hook the scatter node to the topnet, I get a file that has as many lines as my points but nothing written… Do you know how to fix that?

mmhhh try to dirty and cook the geomettry import node before cooking the csvoutput

Same output…

could you upload your scene file

Sorry, my bad… I figured out that i hadn't put the attribute to export in csvoutput…

I managed to get my points and it looks right so thank's a lot!!
