Buggy shadows with multiple windows

[James Davies]

Using setShadowCaster( True ) on a light doesn't seem to render properly with multiple windows. If I set up two windows and use an additional camera to render to the secondary window, my lighting will not look as expected. On some cards the secondary window's lighting doesn't appear at all, on others the lighting appears but the shadow map is "glitchy " and appears noisy (especially when the secondary camera is moving).

The following code should show the issue:

from direct.showbase.ShowBase import ShowBase
import pandac.PandaModules as pm

base = ShowBase()
win = base.openWindow()
cam2 = base.makeCamera( win )

base.cam.setPos( 6, -10, 30 )
base.cam.setHpr( 0, -60, 0 )
cam2.setPos( base.cam.getPos() )
cam2.setHpr( base.cam.getHpr() )

b1 = loader.loadModel( 'box' )
b1.setPos( 3.3, 3.6, 1.3 )
b1.setScale( 2.7, 2.7, 2.7 )
b1.reparentTo( render )

b2 = loader.loadModel( 'box' )
b2.setScale( 12.5, 12.5, 2.7 )
b2.reparentTo( render )

spot = pm.Spotlight( 'newSpot' )
spot.setColor( 10 )
spot.setShadowCaster( True )
spotNp = render.attachNewNode( spot )
spotNp.setPos( 5, -8.5, 3.5 )

render.setLight( spotNp )
render.setShaderAuto()

base.run()
