Cycle through layers and namedviews using python rhinoscriptsyntax

I am an architect, and often I have to do a similar task: I design multiple options for a project, each on a layer, in the following tree organisation:
OPTIONS
– 01
– 02
– 03

I then create a couple of named views. I will then create screen captures for each option, using each namedview. Manually, this is quite a laborious and error prone process, and I think it would benefit from being automate with a little script.

Somehow, if i loop over 1 single option and create a screenshot for each namedview, it works.

(For instance with this code):

import rhinoscriptsyntax as rs

views = rs.NamedViews()

def make_capture(option, view):
    print(view)
    rs.RestoreNamedView(view, view=None, restore_bitmap=False)    
    comm=""" -_ViewCaptureToFile C:\\Users\\vincentk\\Desktop\\200203_Massing_Study\\View{}_Option{}.png 
    _Width=1200 _Height=900 _Scale=1 
    _DrawGrid=_No _DrawWorldAxes=_No _DrawCPlaneAxes=_No 
    _TransparentBackground=_No _Enter""".format(option, view)
    rs.Command(comm,False)

for view in views:
    print(view)
    make_capture(1, view)
    rs.RestoreNamedView(view, view=None, restore_bitmap=True)

But when I create the nested loop with looping over each option, and then looping over each namedview within them, the second loop is ignored and it is only creating a screenshot for the first named view of each option.

import rhinoscriptsyntax as rs

views = rs.NamedViews()

def make_capture(option, view):
    rs.RestoreNamedView(view, view=None, restore_bitmap=False)
    comm=""" -_ViewCaptureToFile C:\\Users\\vincentk\\Desktop\\200203_Massing_Study\\View{}_Option{}.png 
    _Width=1200 _Height=900 _Scale=1 
    _DrawGrid=_No _DrawWorldAxes=_No _DrawCPlaneAxes=_No 
    _TransparentBackground=_No _Enter""".format(option, view)
    rs.Command(comm,False)

layers = rs.LayerNames()
for layer in layers:
    if 'OPTIONS::' in layer:
        print(layer)
        rs.LayerVisible(layer, visible=True, forcevisible_or_donotpersist=False)
        for view in views:
            print(view)
            make_capture(layer, view)
        rs.LayerVisible(layer, visible=False, forcevisible_or_donotpersist=False)

Anyone have any idea / experience with that problem, and could give a pointer?

PS: Also - It seems that when the scene is to heavy, the loop doesn’t wait for the image to refresh before iterating to the next loop element; the script tends to crash rhino altogether in such case, in addition to the problem mentioned above. I have tried to use time.sleep for the screen to have time to refresh, but it seems to be the source of even more freeze and crashes. Any experience, pointers with the help of time.sleep in the context of loops + heavy geometry appreciated as well! Thanks
