the default directories where it exports are not into your main construct directory, from the actual sdk directory its:
..\..\IDE\Plugins\Template.csx
..\..\IDE\Plugins\Runtime\Template.csx
copy those to the construct\plugins\, and construct\plugins\runtime\ directory to find it in construct
to change where it saves and the names of the files go to
project-Template SDK properties: Configuration properties - linker,
and then it's under 'output file'
you'll have to do this for both the Release, and Runtime versions, that you select in the dropdown box of the properties dialogue
also, for these plugin development questions, the appropriate forum is:
construct engineering
you'll probably get a quicker answer, too, since we don't get much action there
also, not sure how relevant this is to your level of programming knowledge, but don't hesitate to ask very basic questions. a couple of us (myself included) basically learned to program c++ using the plugin sdk
