Why I can't transfer “P” attribute values, to second geometry?

[Masoud 14]

Hello;

I wonder why I can't transfer “P” attribute values, to second geometry, by “Attribute Transfer” SOP..!?

 

Thanks for helping.

That is what the "Match P Attribute" checkbox is for.

And in your example, as distance between original points and displaced point is much greater than neighbour points distance, you also need to use source and destination groups.

If you don't need any of the other functionality of the attribute transfer node, it would be faster to use a wrangle:

@P = @opinput1_P;

(line into input 0, edit into input 1)

you CAN write the vex yourself every time if you want to, or if you feel lazy, just a Point SOP, preset Morph to 2nd input then you can have a controlled lerp amount.

I turned " Match P Attribute "on, but it doesn't work.

Thanks, everyone, good tips.

vector pos = point(1, "P", @ptnum);
float mix = ch("mix");

@P = lerp(@P, pos, mix);

Even shorter version:

@P = lerp(@P, @opinput1_P, ch("mix"));
