v-ray sahder
finished version. My attempt. One single element with one very adaptive material applied. Material without any bitmaps. Simple scene with one light so object is not affected by any other elements, backgroud colors or lights - everything done inside material so can be used in any scene on any object. This is pure render from v-ray frame buffer without any corrections (no level, no exposure, no level corections even in max).
