Shadows and multithreads

Scripting Issues
1

I’ve set up shadows using light.setShadowCaster(), but when I turn on multithreading with threading-model Cull/Draw in the config, panda3d freezes up before it draws anything to the screen.

I’ve narrowed it down to a simple example. If both the commented first line and second line exist, it doesn’t work for me.

from panda3d.core import loadPrcFileData
#First line
loadPrcFileData('', 'threading-model Cull/Draw')

from panda3d.core import *

from direct.showbase.ShowBase import ShowBase

class Engine(ShowBase):
      def __init__(self):
            ShowBase.__init__(self)
            base.setBackgroundColor(1,0,0,1)

            model = loader.loadModel("models/environment")
            model.reparentTo(render)
            model.setScale(0.1)
            box = loader.loadModel("models/box")
            box.reparentTo(render)
            box.setZ(1)

            light=DirectionalLight("test")
            light.setColor((1,1,1,1))
            light.setSpecularColor((1,1,1,1))
            #Second line
            light.setShadowCaster(True, 1024, 1024)
            light.getLens().setFilmSize(20)

            base.disableMouse()
            base.camera.setPos(10,0,10)
            base.camera.lookAt(render)
            
            node = render.attachNewNode(light)
            node.setPos(-2,-2,2)
            node.lookAt(render)
            
            render.setLight(node)            
            render.setShaderAuto() 

            self.open = True
            while self.open:
                  print "updating..."
                  taskMgr.step()

If you could file this on the bug tracker, that would be great.
