Help Exporting from Blender and Importing to MSFS (Video)

Ok, in this folder, C:\Users\bgmsd\OneDrive\Documents\FS2020Projects\SimpleCube\PackageSources\modelLib\texture

I do not have any dds files, or at least files with that extension.

This is when building the project, or building the package? Because I have not been building the package. I figure I do not need to build the package until I am ready to deploy it. Is that right?
