You're a brave soul Alan. I don't trust frozen locations on meshes
further than I can throw them... and I can't throw them at all...
Not something I would recommend myself.

By the way, as long as your locations are in-use (or you got Display
Values on for it) you can freeze the tree responsible for doing the
location lookup and storing it to a custom attribute.
It will "freeze" the locations and it will be way faster when reading
them. The second you change topology though, you'll need to compute
the locations again. Same goes if you want to recreate the locations
or overwrite what's frozen.
I am currently employing this technique in production in a film with
an epic car chase. The cars that crash are being (ICE) cage-deformed
by an outer shell "blob" mesh (through shapekeys to warp them) and
it's effectively using frozen locations to transfer the deformation to
the entire set of meshes in the car relative to the cage mesh.

Thanks Dan,
Glad I'm not going crazy... It's one of those things I thought
that I have done before and worked..

Hi Simon.
The sample set will constantly change with deformations. You
have to emit from a static version and stick to a
re-interpreted location on the deforming version.
It's a little irritating, yeah.

Hello list, happy new year!
I'm slightly puzzled here with locations. I thought that
just having this simple set up would do the job, but alas
it does not (see attached image)
This tree is in a cloud in a non simulated stack, without
time variation and without the seed changing.
I thought that the points should stick to the same
location on the geometry while the geometry deforms?...
The do stick when the object's SRT moves, but not any
deformation..
Now I can get this to work by adding a sim ice tree and
just using*'Stick to Location'*
**But it'd be great if it wasn't a simulated tree, and
more to the point I'm just surprised that the locations
change in the first place....(especially when i can stick
to them afterwards), what is changing every frame
initially? Is location based on the bounding box of the
geometry or something?...
Thanks...
