This is my first attempt at an input object generator plugin object so there are some things that are still a bit confusing.

I found out the hard way not to return the original input object (op->GetDown()) in GetVirtualObjects(). Makes sense as it is part of the cloned document sent to GetVirtualObjects() and is released with that document afterwards I would imagine.

I am using GetAndCheckHierarchyClone() to get a polygonized clone representation but this is further modified. But the original (unmodified) input object still needs to be returned also. Should I just make an additional clone to be returned in my Null object parent?

Also, I take it that if dirty=TRUE then 'res' from GetAndCheckHierarchyClone() represents the currently built cache, modifications and all, whereas if dirty=FALSE then 'res' represents the polygonized input object (hierarchy)???

Thanks!

On the first post, I found an old Mikael Sterner post which suggests that GetClone() should be used for additional copies to be modified (YAY!).

No idea about the second but we'll see.

Hi.

I do it like this:

if it's dirty, then I build my virtual object hierarchy and return it.

if its not dirty then I return the 'res' from
GetAndCheckHierarchyClone(), which i think just means that nothing has changed, and cinema can use the cached virtual hierarchy.

greetings,
Daniel

That should have been in my second post:

dirty=FALSE, res=built cache
dirty=TRUE, res=polygonized input

And that, as you note, seems to be the case.
