Select one or many point cloud objects and run.
I hope that help you.

Have a look at the 'create polymesh from instance shapes' addon on rray, it
merges the instances and preserves UVs.

Sure I'll have a look at the script if you have it handy.

In case we are talking about static instances then I would export
the particles and instance again in maya.

Otherwise Momentum got a tool called "Instancer" which should do
what you want.

Hi all,

We need to back out some ICE instances to geometry with UVs to
transfer over to Maya. What's the best way to go about this? I
thought I'd seen one of the Mootzoid plug-ins able to do this
but not sure which one it was or whether actual UVs were
generated or if they are just ICE based.

Any help is appreciated as always,

Hello,

At least, a simple script can read point clouds data and create all
instance objects (can be critic if you have many many particles).
I can share my script if you are interested.

Best way to back out ICE instances to Geo + UVs

[Eric Thivierge]

Hi all,

We need to back out some ICE instances to geometry with UVs to transfer 
over to Maya. What's the best way to go about this? I thought I'd seen 
one of the Mootzoid plug-ins able to do this but not sure which one it 
was or whether actual UVs were generated or if they are just ICE based.


Any help is appreciated as always,
