Final Gathering and transparency 2004-03-10 - By Jeff McFall

Not sure what happened with the formatting on that last script - this one
should work better....
CreateImageBasedLightingPass "Pictures\noIcon.pic"
CreatePrim "Grid", "MeshSurface"
SetValue "grid.grid.ulength", 30
SetValue "grid.grid.vlength", 30
ApplyShader "Lambert", , , , siLetLocalMaterialsOverlap
CreatePrim "Sphere", "MeshSurface"
ApplyShader "Lambert", , , , siLetLocalMaterialsOverlap
SelectObj "Camera"
ToggleVisibility
Translate , 0, 20, 0, siAbsolute, siParent, siObj, siY
SelectObj "sphere", , True
Translate , 0, 4, 0, siAbsolute, siParent, siObj, siY
InspectObj "Passes.HDRI", "General", , 1
SetValue "Passes.HDRI.Environment.background_intensity", 0
SetValue "Passes.HDRI.Environment.fg_intensity", 0.35

No,
Ive included an image to illustrate as well as a slightly modified script which
I think better represents the issue.
Run the script and adjust the opacity on the sphere, when 100 % transparent it
still makes a shadow

I ran the script. When the transparency color (in the Mix Color group) was set
to black, I got a small gray grid casting a white "shadow" onto a large gray
grid. When the transparency color was set to white, the small grid was
invisible and the large grid had no shadow on it. Are these the results you're
getting?
