Particle Sampler Info node's isssue

[excentriPMNA2]

I read the manual of arnold render.(

https://support.solidangle.com/display/A5AFMUG/Particles)

but, after i downloaded the file, i rendered, but, the particle don't change over time.

what problem?

The particles themselves render fine in Maya 2017 Update 4 with the latest MtoA.

There's a translation error for the ParticleSampler: Arnold node type MtoaUserDataFloat does not exist

Try using an aiUserDataFloat to get the "age"

thank you for your reply. the description of manual lacks. i make ai user data float node and connect the node into the shading network. that time, everything worked well.
