George, I tried recreating the genlocked sky effect using Imagine 3.0, but my efforts were as fruitless as yours. Seems like Imagine will not render using color 0, period. As a test, I placed a chrome sphere in front of a black plane, and gave the Globals a nice gradient for the sphere to reflect. The result: a shiny sphere with a black background… but the background uses color 1. I switched colors 0 and 1 in DPaint, saved the image, and told Imagine to re-render the scene using an external palette file. This would force Imagine to draw the background in color 0, right? Wrong. Even though color 0 was now black, and the plane behind the sphere was black, Imagine used _color 15_ as the background, which was a dark brown. Yep, brown, not black. Seems like Imagine picked the darkest color it could find in palette positions 1-31. The way I see it, Imagine 3.0 will never render using color 0, period. A solution would be to render in 24-bit mode, and use an external program to compile your animation; that program could be locked to a predefined palette. (Create the palette from a sample still from your animation) It's a bit annoying that Imagine 3.0 ignores color 0. This is actually _decreased_ functionality compared to 2.1. Blaq!
