Shadow Mapping not working on latest devel builds

[consultit]

Up to devel builds before 20111227 this code worked fine:

################
from direct.showbase.ShowBase import ShowBase
from pandac.PandaModules import *
from direct.actor.Actor import Actor

app = ShowBase()

# panda
pandaActor = Actor("panda-model",{"walk": "panda-walk4"})
pandaActor.setScale(0.01, 0.01, 0.01)
pandaActor.reparentTo(render)
pandaActor.loop("walk")
#plane
cm = CardMaker("plane")
cm.setFrame(-20, 20, -20, 20)
plane = render.attachNewNode(cm.generate())
plane.setP(270)
plane.setPos(0, 0, 0)

#Directional
Light1 = DirectionalLight("light1")
Light1.getLens().setFilmSize(40,40)
Light1.getLens().setNearFar(-20,20)
##Light1.showFrustum()
Light1Node = render.attachNewNode(Light1)
Light1Node.setHpr(90, -45, 0)
render.setLight(Light1Node)

#Spot
Light2 = Spotlight("light4")
Light2.setColor(Vec4(1, 1, 0, 1))
Light2Node = render.attachNewNode(Light2)
Light2Node.setPos(-50, -50, 50)
Light2Node.lookAt(0, 0, 0)
render.setLight(Light2Node)

#Shadow enable
Light1.setShadowCaster(True)
Light2.setShadowCaster(True)
render.setShaderAuto()

#camera
app.cam.setPos(0, -50, 20)
app.cam.lookAt(0, 0, 0)

#run
app.run()

#######################

But latest builds (I tried up to 20120108) give this output on console:

Known pipe types:
  glxGraphicsPipe
(all display modules loaded.)
:display:gsg:glgsg(error): at 4179 of panda/src/glstuff/glGraphicsStateGuardian_src.cxx : invalid operation
...
(.... more lines as above...)
...
:display:gsg:glgsg(error): at 4179 of panda/src/glstuff/glGraphicsStateGuardian_src.cxx : invalid operation
:display(error): Deactivating glxGraphicsStateGuardian.

and window output freezes.

System on which I tried :
* AMD64 - Linux Debian Squeeze - NVIDIA GeForce 9400 GT with driver version 270.41.19

Stable version (1.7.2) works fine.

Bye

Thanks for reporting the issue. It appeared to be due to a change to the FBO code zhao made, which I've reverted for now. Your code seems to work fine on my Mac OS X machine now.

I poked the squeeze_amd64 buildbot, so the latest build incorporates my changes.

I tried that latest build and code works fine again.

Bye
