I've been working on the Xbox conversion of martin105038's Korriban. I'm having trouble updating the lava object to have the cool orange Mustafar-y glow. Below is a hex shot of the MSH file I'm working with. Any help would be hot - I checked out the hex tutorial, but I know I'm doing it wrong.
Also is an alpha channel needed, or does it just play off the texture map? I noticed the default map didn't have one, but I didn't know if this is a different flag.
No, you dont need an Alpha for glow. The brightness of the texture is how you control the level of brightness. Useing a pure White texture will get you a load of light.
An alpha layer is only needed to adjust the intensity of the glow. A more opaque alpha layer will get you a less intense glow, but if it is completely black, then the areas of the MSH applied with glow will appear completely black in-game. And the color of the glow depends on the color of the RGB texture, of course.
