适用于 Iray 的 MMX 资源节省型着色器合集 5

适用于 Iray 的 MMX 资源节省着色器集合 5 专为轻量级设计，涵盖金属和合成材质，包含 6000 种主色预设，颜色范围从单色到双色及多色带。主色分为两组：第一组仅有 1000 种预设，颜色变化非常平缓；第二组则有 5000 种预设，颜色变化更为显著。主色预设基于折射效果，且仅在 Iray 渲染时可见。 次色预设可与主色预设混合使用，从而改变物体表面的颜色效果。次色分为三组：色调、主色和副色。色调选项均为灰度，可帮助控制亮度，避免在光线充足的场景中颜色被冲淡。主色和副色各有 40 种颜色可与主色混合搭配。主色还配有 25 种灰度颜色，与色调选项相同，两套灰度颜色可用于生成深色和黑色。 除颜色外，还有 13 种基础预设选项，可实现从闪亮的铬到哑光粉末等效果。此外，还提供 4 套图像映射，用于改变物体表面的外观。图像映射分为两组：增强金属感和降低金属感。两组内容完全一致，每组包含 4 套映射，呈现 3 个层次的变化，并为每套映射提供 3 种版本。图像映射同样支持法线强度和平铺选项。 主要的基础预设有两种选择：一种适用于头发或其他透明/半透明物品，能保留不透明度、法线、凹凸和置换贴图；另一种适用于不透明表面

MMX Resource Saver Shaders Collection 5 for Iray is designed to be a lightweight, metallic, and synthetic materials set with 6000 primary color presets that range from single colors to dual and multi-banding colors. The primary colors are divided into 2 sets. Set one is only 1000 presets and has a very gradual color shift, whereas color set two has 5000 color presets with a much greater color shift. Primary color sets are refraction-based colors and are only visible when rendered in Iray. The secondary color sets can be used to blend with the colors of the primary color sets, thus altering the color seen on the surface. Secondary colors are broken down into 3 groups: color tone, main color, and secondary color.  Color tone options are all grayscale and can help control the brightness so the color does not get washed out in well-lit scenes. The main color and secondary color have 40 color options to mix with the primary colors. The main color also has 25 grayscale colors, the same as the color tone options, and the 2 grayscale sets can be used to produce dark colors and blacks. In addition to color, there are 13 base preset options to go from shiny chrome to a flat powder, plus 4 sets of image maps to alter the appearance of the surface. The image maps are set up in 2 groups: More Metallic and Less Metallic. Both groups are identical and have 4 sets of maps showing 3 levels of change, plus 3 versions of each map. The image maps have normal strength and tiling options as well. There are 2 primary base preset options. One is meant for use on hair or other transparent and translucent items. It will preserve the opacity, normal, bump, and displacement maps. The other is meant for opaque surfaces.
