Hi, Brian, Thanks for the comments. The roof is definitely WIP. I've run into more than one C2 bug (reported to Eovia) in trying to get this right. For instance, a simple abs(cos(x)) formula doesn't work there and some of the shaders only work in local not global and vice versa. It's been frustrating bumping it. Anyway, I'll tinker more with it and maybe just use a texture map to be done with it (although there is also the 'seamlessly doesn't work in the bump channel' bug ;-) I'll fiddle with the railing as well. It's actually one of litst nice metal shaders but doesn't look so good in the moonlight. As to the moon, I like the lighting straight down for now so that kind of makes a moon on the edge not line up but we'll see. I was thinking of a moon reflected in the canel with the stars (DCG's starbright for the stars) but that would leave most of the scene very dark. Once I get the torch in there, I might try it though. Comments very much appreciated! Marc
