Changing Position of Only One Point in VEX Nov. 12, 2025, 2:27 p.m.
fred_98
I am looking for a procedure that will affect only some of the points of the geometry but I do not know which points exactly and the index of the points are the result of some searching and other computations.
Supposing that you are able to get point numbers after your searching process, you can use get/set functions to modify a specific point based on it's ID/number :
// get point position based on a given ID vector position = point(0, "P", point_id); // adjust position position.y += value; // set the position "P" attribute on geometry only on the given point ID setpointattrib(0, "P", point_id, position);
VEX: Get Path of Node Connected in Input 0? {[SOLVED]} Nov. 4, 2025, 4:19 p.m.
I am not aware of a specific VEX function that does this task based on input number. If you create some spare parameters you can take advantage of Hscript in parameter expressions as it has the deticated functions you are looking for :
- Node name
- Node path
Now, to read this in VEX snippet, you can evaluate parameter channels :
- Node name
opinput(".", 0)
- Node path
opinputpath(".", 0)
Now, to read this in VEX snippet, you can evaluate parameter channels :
string node_node = chs("node_name"); string node_path = chsop("node_path");
copernicus nodes as cop filter Oct. 14, 2025, 5:31 p.m.
This feature uses a
It has a TAB menu filter to only grab nodes under
You could simply set this filter to * and it will allow all nodes to show in TAB menu and place what ever you want, and the created nodes will appear in the Filter List interface. But of course there's a good reason why the TAB menu is limited to Filters/Post nodes as they are designed with a "filter/effect logic". So you have to be carefull about nodes that you want to use in Filter List.
I would suggest that you carefully design your own Digital Assets/HDA and save them under Filters/Post TAB Menu, and they will automatically appear in Filter List interface without further effort.
