got a bit of a problem with GI_Joe - I set it up using the default settings, then add the specular, then put a environment map in to the sky and ground colours. renders fine. reasonably bright. then I change the default from 0.1 - 0.15 and the images goes darker!!! what's that all about - is it a problem with the default isn't actually 0.1 but displays that in error? what defaults does your GI_Joe give for light intensity?
