Atoms support Renderman, Arnold and Vray renderer. There are procedural for each of these 3 renders that can be used inside maya/houdini or standalone.In maya with arnodl and renderman
Maya
It is possible to render each agent group as a normal maya node, just lunch a render and the procedural are automatically loaded. But pleas ebe please be aware the motion blur will not work if you render directly an agent group inside maya.
You must export a cache of your simulation and then use an AtomsProxy node to load it in the scene. The Atoms proxy node support the motion blur.
In With Vray just the Atoms Proxy node works. Is not possible to render directly the agent group nodes.
Houdini
In houdini to render you simulation, you mast export an atoms cache and the create a Renderman/Arnold procedural node from the Atoms menu
