I also do this at the very last step AFTER resizing. What I usually do is make a circle selection that touches the boundaries, invert it, and then fill with a solid color, usually the same color or darker than the edges of your image. When doing final 8bit export ive found that the program IRFANVIEW tends to give the best results and less banding/noise than even photoshop at times.Ī big tip is dont waste pallete entries You only have 256 colors so to reduce banding make sure the outer, not mapped gaps either have a solid color or no other stuff or else you are wasting colors that could be used. I generally avoid dithering when indexing BMPs to reduce noise. Due to the small resolution sometimes "surface blur" helps with this a lot before resizing for "busy/noisy" images. Lots of different colors can be an issue due to pallete limitations. Basically smooth simple gradients are nice, where as a lot of busy or noisy detail will look bad. When authoring chrome images all edges of the sphere area must touch the boundaries, generally best to use an image that isnt "too busy" or detail. Also you can swap out existing chromes with HLMV in texture tab. This guide assumes you know about model compiling, if you do not head over to The MDL Guide. A Neat thing of note is that with chrome mode existing UV's are unused due to the nature of it, so if you are making an object or part that you are sure is gonna be chrome, you can skip UV Unwrapping procedures. You can make things look plastic, metal, shiny, underlit, rimlit, toon shaded, and even outline. This allows for a wide variety of effects depending on how you make your sphere image. The way this works is that the spherical image space of the texture is mapped by the corresponding normals of the object. Authoring of chrome is often misunderstood, so I wrote this guide to make the best of this and to begin ill state that "Chrome" textures in GoldSrc function identically to what is more known as "Matcap shading". The Chrome effects most notable examples are barneys helmet, the magnum revolver, the gauss gun, and the alien grunt armour. "Chrome" in GoldSrc is a special texture mode that allows for a simple environment-like texture that is limited to 64X64 (However Sven Co-Op has removed that hard limit).
