Hi, DeadClown! build 0.15 of your script is working really fine with latest corona's builds, but i have a suggestion.
As we know from oficial FAQs in corona it is recommended to make albedo between 0,7-0,8 (depends on type and colour of material,of course), so may be that would be a good idea to make this function directly in script, so it not required to make it in all converted materials by hands. for example, make some additional parameter, where we can write value of albedo, tick it on and this number will apply as albedo number in all converted materials.
anyway, thank you for this very useful script!
