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.
