Save SpeedTree file as .srt

I am using SpeedTree UE4 Subscription v7.0.6 and when I click on “Save as with assets” or “Save as”, I only get the option to save it as a .spm. How do I save it as a .srt? I tried installing “Microsoft Visual C++ 2010 Redistributable Package” (x64) and (x86), but both say I have a never version installed. Thank you.

SPM (speedtree procedural mesh) is the file the Modeler uses.
SRT (speedtree real-time) is the file UE4 loads.

The Modeler will make an SRT automatically when you save. It’ll be next to the SPM file. Or, you can run the Compiler directly to make SRT files if you want to do something special.

This documentation section describes the process:

Under the drop down menu when clicking save as, the only option is .spm; there is no .srt option

The Modeler will make an SRT automatically when you save. It’ll be next to the SPM file

Sorry about the confusion, I found the file. Thank you for the clarification!
