Render to PictureViewer without breaking plugin

Now that I've finally figured out how to create radio buttons in a res file (why was this info not available before in the forums?) and bitmap icons, there are just a few remaining roadblocks that I have become accustomed to. If anyone is feeling magical and want to try to answer another longstanding question that I haven't been able to figure out, here you go (Thank you in advance!) :
I have to break my plugins before Cinema will allow me to render to the picture viewer. This hasn't been much of a problem because I need to break the plugins anyways to hand my projects over to my co-workers who are too inept to follow my repeated instructions on how to install my plugins (Anyone else have this problem?). What code do I need to allow me to let Cinema render when I have an object plugin in the scene? Let me know if I need to post any example code.
P.S.: Yeah, I know that these seem to simple questions, but as it turns out, the basics are the hardest things to find answers for in programming.

Hi David,
can you please elaborate a bit more? What do you mean by "break my plugins"?`
Also not sure about the "special code" to let Cinema render. I guess, you already know the Py-RoundedTube example from the Python SDK. This renders just fine. -

Hi Andreas,
By "break" I meant Make Editable. Most of my object plugins don't render unless they are Made Editable, but some do. I'll go ahead and post an entire plugin if it helps. It doesn't have all of it's problems worked out, but the basic functionality works fine:

Hi,
I'm sorry, we are not supposed to debug code. And it would be a good idea to give at least an overview, what your code is supposed to do.
I briefly looked over your code and I think you have several problems in there.Most important:
You are not allowed to modify the active scene with GetVirtualObjects(). Please have look at documentation on ObjectData, GetVirtualObjects() and important threading information.
I noticed for example MergeDocument().Objects can only be inserted once into a scene, while you try to get the active object and insert it under your generated object. That won't work for several reasons:
- The active object is already in the scene and you can't remove it, because you are not allowed to in GVO. Instead you should have a look at the OBJECT_INPUT flag on RegisterObjectPlugin().
- Getting the active object makes no sense during rendering. The scene gets copied for rendering and there simply won't be any active object in there.You are loading several scene files with MergeDocument(), which (as mentioned before) already is a bad idea, but think of situations like for example TeamRender. How is TeamRender supposed to find these files on a different machine?
I think, you will have to rework and restructure your plugin to properly work in all situations, especially for rendering. Sorry, to say this.
