In H15, using a Point SOP to add a normal attribute to a mesh creates normals with a 0,0,0 vector.
It works fine in H14.

To make it work I had to add a Normal SOP before the Point SOP.
Could someone explain this?
Is this a bug or new functionality?

Cheers

The odd thing is that the normal view in the 3D view shows proper normalized normals.
in H14 they are 0,1,0 as expected

at least could someone else confirm or deny this?
:-)

Thanks

you can use $NX not @N.x and so on

thank Jerry,
I did indeed try that and it worked.
I was wondering WHY did this change if it doesn't actually work properly.
Does the new @N.x format offer any advantage?

Cheers

I guess it is by design. The doc indicate that SESI dose not suggest use Normal Parameter in Point sop, except modify existed N attribute.

Normal vector. If you just want to compute normals, please use the Normal node instead.

thanks again for your time
