For the asset previews we are using an additional in-house script called Library Submit. It is used to submit the render previews to Deadline and queue them up. After they've rendered, we need to remember to manually assign the previews to our asset in Connecter. Below there's a video with details of the process.
Generic Asset Preview Submission
After the asset have been saved in the proper folder, start the Library Submit script.
In the Asset Location browse and find the proper folder.
Under Asset type select Generic.
Under Asset placement choose a render setup. Floor refers to camera from above, Wall to a front on camera, Ceiling to a camera from below.
Press Submit Previews button.
Wait for the Preview Submission Success pop-up window for confirmation.

(Optional) If used, under Displacement Amount add the the correct figure, always in cm.

Render Management
After the previews have been submitted, open Deadline Monitor.
Find render group named with [LIBRARY][SINGLE FRAMES] and the Asset Name.
Queue the render(s).
After previews have been rendered they are automatically saved in the THUMBS folder. They need to be uploaded as thumbs of the individual models. You can see more about the process HERE
