I'd like someone else to verify this so I know it's not just me being stupid somewhere.

Open a new default scene in Poser 8 SP1.
Navigate the Object Palette to show the Properties of Light 1; should be Depth map shadows & Shadow Blur Radius 2.0.
Open the Scripts>Python Shell window and type in the following:

light = poser.Scene().Lights()[0]
light.ShadowBlurRadius()

Should return 2, which agrees with the GUI

light.SetShadowBlurRadius(6)
light.ShadowBlurRadius()

Should return 6, which agrees with the changed GUI

light.SetRayTraceShadows(True)

GUI Shadow Blur Radius changes to 0.0!

light.ShadowBlurRadius()

Python still thinks it's 6!

llight.SetShadowBlurRadius(2)
light.ShadowBlurRadius()

Python now thinks it's 2, but the GUI still thinks it's 0

If you render as the scene now is, the render engine takes the value of 0 from the GUI, not the value of 2 from the Python. If you change the GUI to 3.0, the render engine will now use 3.0 for the Shadow Blur Radius even though Python still thinks it's 2.

If it's not just me, this is not how it behaved before SP1 and, in my mind anyway, is certainly wrong. Anybody confirm this?

Is this exactly what is written?  There is an error in line 11, you have a double "L" in light.

Sorry aboiut the typo. It is only in that posting, not the actual test. Thanks for spotting it.
