UnitySceneExport2PhysX3

This is a unity editor tool to help game server developer to rebuild the physics of the client scene using PhysX 3.x or newer.

You can use a simple export button as shown below to export your scene to a xml(or binary) file.

Then you can rebuild your scene using C++ with a few line of codes like below:

bool PhysicsSceneManager::ParseFromCollectionFile()
{
	PxCollection* shared = NULL;
	PxCollection* collection = NULL;
	char *filename = "your scene file path";

	PxDefaultFileInputData inputStream(filename);

	collection = PxSerialization::createCollectionFromXml(inputStream, *m_cooking, *m_registery, shared);

	m_scene->addCollection(*collection);

	return true;
}
