Awesome, thanks. If I understand, even though I might be pulling local from Emby for some things, if Emby does not have certain texture files, kodi itself will go to the internet to get it.

When caching artwork, Kodi will pull the original artwork from whatever url location is defined in the media library - this might be local (a file, or Emby) or internet.

It's your scraper that will make the decision to use local or internet artwork. Once that decision is made, if the file becomes unavailable for any reason, you won't be able to cache it and will get errors when doing so.

So yes, if Emby (which I know nothing about) doesn't have some things, then it's entirely possible your scraper may use an alternative (internet) location for artwork. Kodi will then honour whatever location is set by the scraper when it comes to caching the artwork.
