Hi entry-newspaper,
I'm unaware of a different way to get the data easier or faster into the Vertex Tag.
Perhaps the Freeze can store those better if they don't change. In the moment they are stored, the selections can be switched off.
You can check the specific processing time in the
Main Menu> Window> Object Profiler.
I can't say more since I have zero data about your setup.
If an example is below 1MB, it can be attached here as a c4d file (never use zip, rar, or anything here in the forum.
Given that the file is larger, I will touch only DropBox, Wetransfer, Google, Adobe, or Apple services for security reasons. Please, no tiny Uad, no zip or rar, e.g., for the upload. The URL is just pasted here, not HTML -hidden Hyperlink. Sorry for the long text, it is all about security.
Enjoy you weekend
