[SOLVED] Deleting nodes loaded from FbxImporter

[javier.serrano]

Hi, I have faced some problems when reloading world after loading nodes that were imported with FbxImporter. SDK is 2.9.0.0 and application is 'Only Unigine Script'

The app workflow is the following:

1. App looks, at startup, for all FBX stored in some known folders. Being each folder a type of entity.
2. All FBX are imported and stored in a temporal folder.
3. When all FBX and its '.node' files are created, some instances of each FBX are loaded in scene via node_load()
4. Nodes can be deleted and loaded again many times. Nodes are deleted via node_delete()
5. When app is closed, all nodes are deleted.

Runtime create/delete works fine but when we run world_reload command, the application crashes.
We tried same behaviour but, instead of using FBX nodes, using nodes created in editor. In this case, application does not crash on world_reload.
We exported this non-crashing nodes as FBX with editor. Using these FBX also makes an app crash.

I have attached an example (without bin/ folder) that reproduces the issue.

Any tips of what may I be doing wrong?

Hello Javier,

I've reproduced the crash, we're investigating this. Will update you as soon as get any news.

May I ask you why 2.9? The initial release had some issues and we patched it. Please, use 2.9.0.2.

Thanks.

Hi Morbid,

I just made a quick sample in 2.9.0.0 but App is in 2.9.0.2. Crash appears in both versions.
As runtime create/delete is Ok, we don't need a quick fix but we have plans for changing world in the future.

Thanks!

Hello Javier,

Just wanted to notice that this crash was fixed in 2.10.

Great news. I'll try to update project to 2.10.
Thanks!!

I've discovered a new issue with your sample in 2.10. These nodes operations made a phantom copies in the scene origin that remain even after deletion.

However, this was fixed in 2.11, stable release ETA — end of March.
