Extension methods - onPostInit, onInitTD

TouchDesigner Documentation
1

Hello Derivative team,

I’m have a question about the built-in function of Python Extensions, specifically regarding onPostInit().

I’m trying to understand from which version onPostInit() was originally introduced. I’ve carefully reviewed the release notes from 2017 up to the latest versions and could not find any mention of onPostInit() being added. The only reference I’ve found is in the release notes for build 2025.31550, where it is stated that onPostInit() was renamed to onInitTD().

I am working with TouchDesigner 2023.11600, where the onPostInit() function does not appear to be called. Could you please clarify in which version this function first appeared?

Hi @egrinore,

this function was added to the 2025.30k branch sometimes in late April 2025 and renamed for 2025.31550.

cheers
