Hi Im trying to create a 3D model of a large medical center in C5, nestled on a city street at night. The building consists of a large central tower with four smaller satellite towers attached to it by translucent tubes. The scene I want to do is at night. Now my problem is that while I can get some lighting to work on the smaller towers, I cannot seem to get it to work on the larger one. The main tower is a simple 10 sided polygon, rotated ot the proper orientation. I have created a skin texture in PSP X to make floors and windows. The window areas on the map are white. In C5 I created a layered list texture with the base layer being a simple light blue color with about 10% reflection, and a transparency of 95%. The second layer is where I chose a multi layer shader with the texture map as the color, bump and glow (with color inverted for the glow). In each, I have white is invisible checked so the main layer will show through the window areas and reflect light slightly. I then added an anything glows to the tower and set it to use the objects glow. The problem is for some reason the tower refuses to light up. Any ideas? I have used this technique on several other models but they were done in C4 not C5. Im not sure if something is changed in C5 which stops thid from working anymore or not. Any help appreciated. I will attach a shrunken down version of the texture map to this message in case anyone wants to take a stab at it. The image is resized and converted to jpg format from bmp to save transfer time. Original Image 3000x3000 16M colors BMP. Sorry I had to shrink it so much but the 200K limit on uploads necessitated it be 800x800 resized. If anyone wants the original texture email me for it at sparrownightmare@verizon.net

I think maybe your problem is where you say you have white is invisible. You might use your map in the alpha channel to let the light come through.

Up until now I hadnt even used the alpha channel, Ill give it a try. "The more they overthink the plumbing; the easier it is to stop up the drain..." (Lt. Cmdr. Montgomery Scott UFP)
