Hey,

My current TOPs setup:

1. Wedge with 2 attributes and a wedge count of 4.
2. Rop Geometry: Grabbing a pyro sim. I'm writing this out to a bgeo ($HIPNAME.simcache4.`@wedgeindex`.$F.bgeo.sc), cooking frames as a single work item. It's set to 'in-process'.
3. Rop fetch: This fetches the Octane ROP. Cooking frames as a single work item, and in process too.

The reason I opted for 'cook frames as a single work item' is that I've found (likely to my misuse of the setup) is that the cache will be ignored for the rendering side, so it's constantly caching the pyro sim before rendering the image.

My current setup technically works, but from here what I'd like to be able to do is run this into imagemagick to create a montage of each frame (so frame 0 of each sim, frame 1 of each sim etc). With the current setup - where I have 4 work items (a work item per frame sequence) - I'm not entirely sure how to tell it to look within those sequences, find frame 0 for each sequence, and render an image of that. In previous setups where I've had access to every work item for the sequence, it's been possible, but not sure how to approach it here.

Any help would be appreciated!
