rtfm not really helping here
Â
i have a cloud of points, and an empty cloud....
Â
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?

so far so good, but i need to clone points from 7 clouds into one (wrangling LIDAR data)
Â
point order/ID will be bricked from cloud to cloud
Â
i just assumed (in fact i read in the manual) that attributes would be cloned?!

"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."

ahhh that's enlightening
Â
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
Â
i'm guessing that colour isn't initialised on the original cloud
Â
will experiment

Â
I had some quick fun with it. Hope it helps.
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!
Â
and surprisingly, Soft is coping with 70million+ points quite well!

Â
i think it didn't work because of the way the clouds were created... they are frozen, baked out from a cache file

Sounds like you found a solution...

You can avoid that by setting fake values on the clouds that miss them. hope that works for you!
