Expression Help: Determine Start Frame of Batch

Hello, via standard Batch expressions, is there a way to determine the Start Frame or first frame of the Batch Group?


Not that I have found, and I have looked. Otherwise it would have been built into the fluidmorpher. It’s probably someplace in the ascii file of a saved setup, but the rigamorale of extracting it via some sort of python script is far more difficult and unelegent than just inputing it into a variable node manually. If someone has a better answer, I’d love to hear it.

Same. That’s what I did when I wanted to use your setup in Batch:


The keyword startframe was added to the expressions in the Flame 2017 Update 1 release.

Interesting. When Where can we see that documented.

Seriously, not only is this not in the documentation, I can’t even find it in 2017.1’s “What’s new.” Normally I tend to keep my comments on the polite side, but expressions documentation sucks ass!!! All I can find is “Start Frame,” which is not even a function.

I wonder what other keywords were added that we are not aware of. Surely “startframe” can’t be the only one.

I’m seeing that documented for the python API, but not the basic Batch/Action expressions.

I don’t believe that refers to setting or identifying the start frame of a batch. Different syntax and different application.

This is awesome, makes things so much easier, but it really should be documented.

Thank you.
