Hi johnnyturpin! Sorry for the delay, I just saw this (I usually watch the topics in the Development Tools > Other Tools forun).
It’s a bit intense, and possible to give the exporter very unusual options, which is why I usually point people to
nvtt_export's command line or recording Photoshop actions directly (which might be an easier way to go here in terms of splitting up images and then saving them out).
However, if you want to script this interface to the Texture Tools Exporter, here’s how to do it (presented somewhat generically, since the exact commands between JS, VB, and COM vary a bit):
- Install Adobe’s
- If you save an image using DDS while the ScriptingListener plugin is active, it should record all of the commands and settings you’ll need to set the complete state of the DDS exporter. It’s going to be a bit long and comprehensive - I don’t know if all of them are needed, as the default options will work in many cases.
