Hi,

I am running a little test where I am trying to access the attributes of the next and previous points in a point cloud.

This might be a dumb problem since I've probably neglected something but why doesn't this work?

I am attaching the hip file.

Thank you in advance.

Edit: You can ignore the "distance" line. I forgot to remove it from the file as I am not using it.

the point(0, ...) function is looking for the attribute on first input geo and in your case that geo doesn't have "pos_dir" attribute

so you may need to split your code int 2 wrangles

Splitting it into two wrangles works.

Thank you!

If you are creating new attributes, you can't access these in the same wrangle node for other elements as they are not created yet.

So like tamte said, you have to use 2 wrangle nodes.

If you compile them, you would get the same performance as if they were one node.
