Hello and good evening,
How can one change the little preview thumbnail for a ztool or zproject file in lightbox? I was looking to organize the way my files appear in lightbox, so I can figure out which file is which by image not just by name.
Thank you for your time 
Hi @JefDeChef
ZBrush takes a snapshot of the top subtool in the subtool palette and uses that for the thumbnail. Whether you save the project or the tool, it’s the same thing. So, make what you want displayed and put it at the top of the Subtool palette or if you want a particular subtool on the thumbnail, put it at the top.
Oh thank you thank you for answering @zber2 ! 
Ah so that’s how it works. Although for some reason, some of the default projects like the drone shows the whole model instead of just the top most subtool. When loading that drone project, the active subtool after load up is a lens that’s towards the bottom out of the whole list.
Any ideas? 
Keep in mind that ZBrush has a mind of it’s own sometimes. Maybe the number of subtools has something to do with it. I’m not sure. Anyway, regarding the drone model, if you turn the visibility off for all the subtools (holding Shift key and clicking eye icon on subtool), then select any subtool, it will use that for the thumbnail. Although I could never figure out how the camera works when it takes the snapshot. In most cases it will use the top subtool.
Duly noted thanks Zber
