Get parameter from another node into VEX

[plazadelmar]

Do I use the chf to access the parameter in another node?

For example, accessing scale in transform node from wrangle.

A quick way to avoid guessing is to find the parameter you want to fetch (VEX can't write to parameters), right-click and copy it to the clipboard. Return to your empty wrangle node and paste as relative reference into the empty text box. This should give you a back-ticked ch() type path that you can use inside your vex code.

f@rows = `chs("../sphere1/rows")`;

I tested this morning and I cant make it work, the scaled value by half is not affecting the outcome f@scale = `chs("../transform1/scale")`*0.5;

That's odd, it works for me. The resulting value from the transform scale is cut in half and stored on the points. As I mentioned in the post before, VEX can't write to parameter fields. Are you expecting the value of the upstream transform to change?
