TOPS PDG question. What are some common causes for your TOP network render to fail (no tasks completed) even though there are no errors ( all green icons)?
This happens repeatedly for me when running a FileCache TOP on a simulation. All tasks get executed very quickly but nothing is cached.
Doublechecked and my DOP Network and Default Object paths are correct.

What is your cache mode set to in the file cache node? Usually if everything is green right away, it means that it thinks that the files are already on disk. Can you middle-mouse on one of the work items and verify that the file output exists?
