vray matte alpha

[titane358]

Hello
I did a line of script to see which object as no alpha
-----------
$*.wirecolor = black
for bbb in objects where getUserProp bbb "VRay_Matte_Alpha" == 0.0 do bbb.wireColor = red
------------
but I can't manage to compare "VRay_Matte_Alpha" != 1.0 or with "<="
can anybody help ?
Thanks

although the user property you are getting ("Vray_Matte_Alpha") is representing a float value, it is actually a string... if you want to compare the value to an actual float value, you need to convert it first:

for bbb in objects where (getUserProp bbb "Vray_Matte_Alpha") as float == 0.0 do bbb.wireColor = red
