Is there some sort of geometry cache with Keyshot???

[rotoRob]

Okay, so I am doing some material tests with a model I will be rendering next week and have encountered a problem.  After modifying the model in SU (17.2.2555 64-bit) and then re-exporting the geometry using the Keyshot 7 Exporter plugin (7.3.14) to Keyshot (7.1.51), the model never seems to update.  I have created new Keyshot sessions and have even closed the program between exports out of SU, but the original geometry still appears.

Is there a cache somewhere within Keyshot that would be causing this?  And if so, is there a way to clear it?

I've tried several "workarounds" (i.e. - renaming the file in SU and then exporting, pasting the geometry into a new SU file and then exporting, etc.), but the geometry that was originally sent to Keyshot keeps appearing. 

Any insight into what is causing this issue would be immensely helpful.  (Running Windows 10.)
