That make sense as arrays data is not accessed from the Group
Geometry node in this case. Thanks for the precision Grahame :).

The issue with arrays occurs only when you try to get
attributes directly off the group, e.g., emit particles at
Group.PointPosition.
In the case below, where you are reading attributes at
locations on the group geometry, there is no problem.

not a problem, i am merging 7 LIDAR scans, each of which has
over 10 million points... a few thousand missing ones won't
make a dent!
and surprisingly, Soft is coping with 70million+ points quite
well!

Subject: Re: cloning points with attributes
If I remember correctly, the Group Geometry node will re-size
any 2D arrays to the smallest on in the group. So the new
point cloud could will miss some data (incomplete strand
positions for example). I didn't double check it, but just in
case :).
Cheers,
Guillaume

Hey Adrian,
I would recommend to collect all your pointclouds with a
group Geometry node and plug it into a "Generate Sample Set"
with emission type set to "Point" and Rate type to "all
Points" Rate should be set to 1.
then you can get whatever data is in the pointclouds via a
"self.emitlocation" and pull the data you need from this
Location.
you will get a red node if there are custom attributes that
are not valid for all clouds. You can avoid that by setting
fake values on the clouds that miss them.
hope that works for you!

ahhh that's enlightening
the clouds i'm cloning from were created with a custom script
that reads positional and colour data from lidar files,
creates a cache, loads the cache on a new cloud and freezes it
i'm guessing that colour isn't initialised on the original cloud

Subject: Re: cloning points with attributes
Hum, it should just work out of the box: it's meant to be a
direct clone, attributes and all. Just done a quick test and
it seems to work fine for me with Color (though this is in 2012).

i just assumed (in fact i read in the manual) that attributes

"All attributes of the source point are available on the
target point. For example, if you want to modulate an
attribute on the target point based on the source point."

Subject: Re: cloning points with attributes
You can get the point position from the main cloud plug it
into an add point node and then use a switch context node to
get the color from the original cloud over into the context
of the cloned cloud. Since they both have the exact same
number of particles and since they are ordered the same way,
it works very well.
Attached an image with the nodes I have in an unsimulated
ice-tree on the cloud you are cloning to.[Inline image 1]

i have a cloud of points, and an empty cloud....
using clone point (and a test point in volume) i can copy
points from one cloud to another, but the attributes don't
clone... i need the colour to be the same
any tips?
