Peak Sop Local Variables?

[peliosis]

What is the problem with peak SOP? I was sure it accepts $PT and $PR but it appears to be most embarassed with them.

How to move points randomly along their normals then? point sop uses global transform so is a bit useless here.

My example is a very simple one, there is a deformed grid with uniqued prims, I have to randomly displace points along their normals.

Should I use particle sop set to "modify source geo" or prepare my own vex sop or is there some mystery with peak?

Custom VOP

or

$TX+$NX*rand($PT)*0.1, $TY+$NY*rand($PT)*0.1, $TZ+$NZ*rand($PT)*0.1

in a point sop......

or

VEX Mountain

Can't you use the VEX Mountain SOP?

I promise this was my last question today

Anyway, wouldn't it be nice if we had standard variables in this SOP.

Simon, give me a few days to analyze this expression

Thanks a lot

But...actually neither vex mountain nor Simon's expression work like peak SOP.

You can try three of them on the most simple polysphere.

Again, that's not THAT obvious.

edit:

I created custom VOP SOP: displace along normal with amount param, connected to point position.

It works just like peak but what to do to make it work with $PT?

I'm so close

edit:

Got it, I still don't know how to use $PT, but approached with non deterministic random with multiplier plugged into amount and I'm home.

thanks
