Why is it not possible to delete P with attribute delete?


Recommended Posts

I ran in to this problem, because I have a sphere, and I need a deformed version of it, but only as a rest attribute. I know how to do this in other ways, but I thought, that to just make the deformation, create the rest, delete the P attribute and then merge it with the original sphere would be nice. But when trying to delete the P attribute with a Attribute Delete, nothing happens?

Is this because P is a special attribute or something? Would be interesting to know.

Plugin both versions in an attribwrangle. Then you can take over the rest attribute from the second input with:

v@P = @opinput1_rest;

Morphing between both positions would be:

v@P = lerp(@P, @opinput1_rest, chf('morph') );

Point positions cannot be deleted, but you can set them all to zero:

v@P = vector(0);
