thanks alot, that helps.

one more question on 1.

Most convenient way to go for me is MyCustomModifier way, but what asset type should I set to it? Modifier has a special constant for it, but my objects are custom and it seems that existing constants do not fit into the model.

IDzSceneAsset::AssetType MyCustomModifier::getAssetType() const
{
 return ModifierAsset;
} 

return ModifierAsset;

still a problem I return owned assets but write write functions are never called; I register my custom type with

what am I missing?

thing to note, when it was registered by DZ_PLUGIN_REGISTER_NODE_EXTRA_OBJECT_IO DS crashed on saving scene somewhere on creationg IO object for extra modifier, and there were no any of my functions on stack trace. When I changed this to DZ_PLUGIN_REGISTER_MODIFIER_EXTRA_OBJECT_IO macros crashes gone, but still no writing for those objects.

can I treat

as PostLoadFile in previos saving scheme?

can I treat

virtual DzError DzAssetExtraObjectIO::finalizeInstance( QObject *object, const DzFileIOSettings *opts ) const; 

as PostLoadFile in previos saving scheme?

It’s is sort of implied by the header file but yes, finalizeInstance is the last thing called.  Like the following

for all
- applyInstanceToObject
for all
- resolveInstance
for all
- finalizeInstance

and what about previous question about write functions never called?

maybe you need more details?

That I will have to investigate.

One more strange thing, after loading saved file hierarchy structure is lost, do I have to store it by hand and restore on load?

I am unsure what you mean by “saved file hierarchy structure”?

I mean that scene I save has Nodes, child nodes, etc, when I load it it flattens to the list of nodes, I do not see how I could screw it since no reparenting is done on load.

So question is is structure is kept automatically and I actually destroy it on load somehow, or I should specifically do something to restore parent-child relations?

I just double checked MyCustomNode put into a hierarchy of nodes, it is working.

Are you setting the names of your node to be unique?  use setName on your dznode

it might be helpful to pm me your duf file so I can take a look at it.

from the smallest particle scene resulting file is still big, would not fit into PM, here is dropbox link.

https://dl.dropbox.com/u/21104304/particles.duf

it is big, but when most autogenerated data is folded it is ok to explore.

Search for the lines in the file that look like:

The first node is the camera and looks fine.
The second node looks fine
The third node has no id or name.  I am pretty sure that is the problem.  Please give all the nodes you create a name, it does not have to be unique.

I managed to move significantly futher in my save/load code.

Now I have a question, can I control order of finalize calls for sibling nodes? Or maybe there is some guaranteed order of calls to apply instance, finalize instance?
