Thanks very much for the suggestion. Its no luck for me, frames are still being overwritten.
Gave all the options a go.

Figured out ropfetch overrides any effort of skipping existing frames, specially when set to frame range.
Tried using filerange > filterbyExpression > ropfetch set to single frame. It seems to work, with the caveat that each missing frame will open its own houdini instance.

Hello gang,
Im trying to understand how i can check existing files on disk and skip them. It seems Tops is failing to do so, because im using arnold's ROP as opposed to your typical houdini node.
I tried filerange but i can only get it to crash the scene. Endless loop it seems.
The network is simple, just 2 attributes and then a ropfetch node that would get the output from the fetched node.
Cache Mode is on Auto, and its still recooking existing files.
Any lights on the matter mostly appreciated as usu
Cheers!

Im not an absolute TOP savvy nor use arnold much, but that should be well possible with a python node.
If you have your file path accessible via attribute or similar, you could open it and use regex to edit the file as u need.
