As you can see, i store an idx value and a float value.
Now i want to transfer that information to another mesh with the same number of points, but idx should be the index, and float the corresponding value.
Hm, I may be wrong, but I think when we Sample Index, the “index” value is read from the target object.
Here “idx” attribute is on the source object, and doesn’t exist on target. Try to store it on grid mesh instead.
