I'm testing current "master" branch with FBX assets downloaded from CGtrader, Mixamo, and Sketchfab.
Attempting to import a certain FBX file causes the following crash:

The crash occurs because in FbxLoader.connectObjects(), the child object (with ID 67443872) doesn't exist in objectMap:
|
} else if (type.equals("OP")) { |
|
childId = FbxId.create(el.properties.get(1)); |
|
parentId = FbxId.create(el.properties.get(2)); |
|
String propName = (String) el.properties.get(3); |
|
FbxObject child = objectMap.get(childId); |
|
FbxObject parent = objectMap.get(parentId); |
|
parent.connectObjectProperty(child, propName); |
|
} else { |
|
logger.log(Level.WARNING, "Unknown connection type: {0}. Ignoring.", type); |
|
} |
At the very least, the FBX loader could fail more gracefully, providing clues as to where the problem lies. Probably the best solution would be to warn, skip, and continue.
