display a grease pencil object ontop of a 3d model(despite location) I want the entirety of the grease pencil object to be displayed in front of the model



Is this possible to do without needing to move the grease pencil object?
If you mean to make the GP object always be in front of everything, then there is a setting for it. Check out this tutorial video to find out where (because I can't specifically remember where....):

it's somewhere near the end, like past halfway. it had to do with depth order... may have moved from 2.8 to 2.82.

Hope that helps...
