Zbrush import weirdness

When I connect imported OBJ geometry from ZBrush and connect/delete, the objects in the OM disappear.

This is a weird issue that's been plaguing me for a few weeks now. I can overcome the problem by simply not connecting the objects, yet it still has me scratching my head looking for an explanation.

Any thoughts as to what is happening?

hm, funny stuff, the only thing i could think off is the OHIDE nbit flag. it is a gelistnode
flag you can use to hide objects completely from the users view. not sure how this could
be set by a connect and delete command, but it might be worth a shot.

to unhide run this:

import c4d

def main():
    obj = doc.GetFirstObject()
    while (obj):
        obj = obj.GetNext()

def unhide(obj):
    if isinstance(obj,c4d.GeListNode):
        obj.ChangeNBit(c4d.NBIT_OHIDE, c4d.NBITCONTROL_CLEAR)
        for child in obj.GetChildren():

if __name__=='__main__':

codepad in case of buggy cgtalk formating:

Appreciate the help, but unfortunately it didn't seem to work.

what does

print doc.GetFirstObject()

return ? simply paste it into the console (Script|Console).

Here's a (jerky) 2mb video of it happening; Link

i think you executed it in coffee mode

import c4d

def main():
    print doc.GetFirstObject()

if __name__=='__main__':

or could you save the file and post it ?

<c4d.PolygonObject object called 'myOctaneSettings/Polygon' with ID 5100 at 0x0000000019B642F0>

During beta testing 'MyOctaneSettings' was a null object that was created with every new C4D file, but since the final release this has stopped happening.

If I remove the Octane plugin and re-import, then connect and delete, I get a single polygon object.

Perhaps I should report this to the Octane guys.

yeah that is the downside of using nbit flags, there are dozens of them and if you use
them in hacky way things like that might happen

Well, thanks for helping me get to the bottom of the issue so quickly.

I've informed the programmer over at Octane, it's trivial, but a bug nonetheless.
