ok, use this. adds/subtracts a value to every colorbleed parameter in the scene radiosity override materials.
paste & execute it into the 'new script' window.
---SCRIPT START
new_value=-0.1
--change new_value, negative values allowed.
--will be added to the existing value.
for i in SceneMaterials do
(
try i.colorbleed+=new_value
catch ()
)
---SCRIPT END
if the new colorbleed value would be higher than 1 or smaller than 0 (not possible), nothing is changed with that material.
better would be a little clamp routine, for too high values, and some input UI, but i'm too lazy right now
