I'm trying to copy some Overrides to another object (they are not of the same type, but base properties are still the same, as they derive from Obase)
The following code actually works to some extent, but not for all takes.
I'm pretty sure that I made a mistake here. Also, I don't fully understand the sub-takes yet. Just started with them.
Here's some example code:
inline void TransferTakeOverrides(BaseObject* srcObj, BaseObject* tgtObj, BaseDocument* doc)
// Get doc's take data
TakeData* takeData = doc->GetTakeData();
// Get main take to start from
BaseTake* currentTake = takeData->GetMainTake();
// Set main take active as we need the parameters in "backup state"
// TODO: Disable Auto-Take / Set Mode to manual
// Iterate over all other takes
// skip main take
// Check all overrides for object in current take
BaseOverride* srcOverride = currentTake->FindOverride(takeData, srcObj);
for (auto descID : srcDescIDs)
srcOverride->GetParameter(descID, overrideValue, DESCFLAGS_GET_0);
BaseOverride* tgtOverride = currentTake->FindOrAddOverrideParam(takeData, tgtObj, descID, overrideValue);
srcOverride = static_cast<BaseOverride*>(GetNextNode(static_cast<GeListNode*>(srcOverride)));
currentTake = static_cast<BaseTake*>(GetNextNode(static_cast<GeListNode*>(currentTake)));

Probably can answer this myself.
I simply retrieved the "Backup"-value via FindOverrideCounterPart() and provided this as the backupValue Parameter to FindOrAddOverrideParam().
However, I'm pretty sure there's a more elegant way?

Sorry for bumping this thread, but I would be very thankful for some feedback, if this is the right way.

I'm terribly sorry, when you said, you could answer it yourself, I thought you had a working solution and considered the thread more or less done.
In general it works the way you describe, not sure you would want to skip the Main Take (as the comment in your code suggests), but that's probably a question of the desired final result.
If there's a more elegant way to achieve the same result, to be honest I don't know, yet. I will discuss it on Monday with the rest of the team.
One more note: As BaseOverride and BaseTake are both derived from GeListNode, there's no need for the cast, when passing them to your GetNextNode() as parameters. Might make the code a bit more readable without.

Thanks Andreas, looking forward to your findings.
The cast in the end was from a temporary code. I now use a generic "walker". So, no need to adress it.

we discussed the question this morning, but we didn't come up with a more elegant solution.
So I will just add the link to the Take System Overview page, I had forgotten so far. Don't miss the manual child pages!
