hou.hipFileLoad in multiple threads

[holycause]

question, has anyone tried to run muiltiple instances of hou.hipFile.load() in individual threads, outside houdini?

Whatever I do, it shares the same hipFile accross all my threads

 

cheers

What do you mean by that? If you have multiple processes, then each process has its own separate copy of the scene.

I have my thread Class that loads a hipfile

 

class GetNodesThread(QtCore.QThread):
    
    send_node = QtCore.pyqtSignal(object)
    
    def __init__(self, file, parent, v):
        self.m_file = file
        .....


    def run(self):
        hou.hipFile.load(self.m_file)

and then in my main script create 1 thread for each file

 

#Thread 1
thread1 = HThreads.GetNodesThread(self.m_file1, self, 1)
#thread1.send_node.connect(lambda x: self.getObjLists(1, x))
self.m_threads.append(thread1)


#Thread 2
thread2 = HThreads.GetNodesThread(self.m_file2, self, 2)
#thread2.send_node.connect(lambda y: self.getObjLists(2, y))
self.m_threads.append(thread2)


#Start threads
for thread in self.m_threads:
    thread.start()

I have some additional debugging code writing out information regarding the loaded files and this is what happens

 

/path/to/the/hipfile - loaded_hipefile

 

Thread 1:

Pre load
Z:/devel/python/hipfile_diff_check/hip/sphere_v1.hip - untitled.hip


Loaded
Z:/devel/python/hipfile_diff_check/hip/sphere_v1.hip - sphere_v2.hip
Wrong file

Thread 2:

Pre load
Z:/devel/python/hipfile_diff_check/hip/sphere_v2.hip - untitled.hip


Loaded
Z:/devel/python/hipfile_diff_check/hip/sphere_v2.hip - sphere_v2.hip
Correct file
