"They create their own lights so are not dependant on Poser's buggy light set-up" umm.. i dont think thats possible. the only light sources in poser are the poser lights... you can alter their settings and parameters, but theres no way daz has created another type of 'light source' for poser. there are some python scripts out there, but all they do is automate setting of parameter dials over all lights in a scene, which makes dealing with light sets that have multiple light sources less of a chore. cheers, -gabriel
