UHT2：终极色彩

UHT2：终极色彩是适用于Daz Studio中Iray渲染的通用全包发型纹理解决方案。场景中头发的质量决定了渲染效果的好坏，因此从一开始就使用优质的纹理和着色器至关重要。UHT2是什么？它是备受期待的Iray发型着色器UHT Hair Shaders的后续版本。 UHT2：终极色彩是一套自定义发型纹理和着色器预设，用于替换那些没有Iray材质预设的发型对象上的纹理。不过，UHT2的功能远不止于此。您可以选择在场景中使用发型对象附带的原始纹理，只需添加UHT2提供的优化设置，如光泽度、半透明度和凹凸感，然后使用实用预设进一步优化这些设置。 UHT2还能将头皮纹理转换为Iray格式，并为头皮应用优化设置，同时将头皮颜色与各种发色相匹配。但别急，还有更多惊喜！ UHT2颜色混合器是一款专门编写的脚本，旨在让艺术家能够混合自己的自定义发色，实现几乎无穷无尽的颜色变化、高光、低光、挑染或渐变效果。颜色混合器可用于任何具有垂直对齐UV的发型对象，包括使用原始纹理的发型。UHT2颜色混合器不会更改着色器设置。它仅影响漫反射和半透明通道，因此在现有纹理上混合颜色非常有效。 此外，UHT2还允许将发型纹理在发型模型上平铺多达十次，无论UV映射上的发丝大小如何，都能获得逼真的头发宽度。使用半透明预设，可以让更多或更少的光线穿过头发层次，增加渲染中发型模型的丰富度。使用亮度预设，可以根据需要稍微加深或提亮头发颜色，而无需实际更改纹理的颜色或色调。这对于在较暗场景中添加一点光线，或调暗明亮灯光下过曝的颜色非常有用。 虽然UHT2不能保证适用于所有可用的头发，但它确实能在运行时的大多数转贴图头发上创造奇迹，无论来自哪个供应商、市场、模型或生成器。有些头发使用的是横向而非垂直对齐的UV，或者UV没有排列成条状，甚至可能根本没有UV（例如某些纤维网发型）。这些头发对象无法像垂直条状UV的发型那样从UHT2中获益，但在许多情况下，UHT2设置仍能对其进行优化。 下载包中提供了完整的用户指南PDF版本，还制作了一系列视频来演示指南中概述的一些步骤和技巧。在每个部分结束时，如果已制作视频，将提供对应该部分的视频链接。此外，还制作了一些其他视频，演示本指南未明确描述的分层技术，例如使用颜色混合器为场景中的头发创建渐变效果。所有用户指南视频和额外视频都已收集在YouTube播放列表中，方便观看。UHT2操作指南视频。 不过要小心……颜色混合器可能会让人上瘾！再也不要满足于“几乎正确的颜色”。有了UHT2：终极色彩，一切皆有可能

UHT2: Ultimate Color is a versatile, all inclusive hair texturing solution for Iray renders in Daz Studio. The quality of the hair in your scene can make or break a render, which is why it is so important to start with great textures and shaders. What is UHT2? Universal Hair Textures 2, the much anticipated follow-up to UHT Hair Shaders for Iray. UHT2: Ultimate Color is a set of custom hair textures and shader presets meant to replace those on Hair Objects that do not have their own Iray material presets. But, UHT2 is so much more than that. With the option to use the original textures that come with the Hair Object in your scene, you have the ability to add just the optimized settings for shine, translucency, and bump that UHT2 has to offer, then further refine those settings with the Utility presets. UHT2 also has the ability to convert the scalp textures to Iray and apply optimized settings to the scalp, as well as color match the scalp to a wide array of hair colors. But wait, there's more! UHT2 Color Mixer is a specialized script written to enable you, the artist, to mix your own custom hair colors with an almost endless variety of color variation, highlights, lowlights, balayage, or ombre effects. Color Mixer can be used over ANY hair object with vertically aligned UVs. That includes hair that uses its original textures. UHT2 Color Mixer does not change the shader settings. It only affects the Diffuse and Translucency channels, so mixing the colors over existing textures is quite effective. Additionally, with UHT2 you have the option to tile the hair textures as many as ten times across the hair model, allowing you to get realistic hair widths no matter the size of the strands on the UV map. Use translucency presets to allow more or less light to pass between the layers of hair, which adds to the richness of the hair model in your renders. Use brightness presets to slightly darken or brighten the hair where needed without actually changing the color or tone of the textures. This is great for adding just a bit of light in darker scenes, or toning down blown out colors from bright lights. There is no guarantee that UHT2 will work on literally any hair available, but it does work wonders on the vast majority of transmapped hair in your runtime, no matter the vendor, marketplace, figure or generation. Some hair was made with UVs that run horizontally rather than vertically, or the UVs have not been laid out in strips, or maybe there are no UVs at all (such as with some fibermesh hair). These hair objects will not benefit from UHT2 quite as well as hair objects modeled with vertical strips for UVs, but in many cases they can still be improved with the UHT2 settings. A complete User's Guide in PDF format is supplied in the download, and a series of videos have been made to demonstrate some of the steps and techniques outlined in the guide. At the end of each section, if a video has been made, there will be a link to the video that corresponds to that section. Additionally, a few other videos have been made to demonstrate some layering techniques not explicitly described in this Guide, such as using Color Mixer to create an Ombre Effect to the hair in your scene. All of the User's Guide videos and the additional videos have been collected in a Playlist on YouTube for easier viewing. UHT2 How-To Videos. Be careful, though... the Color Mixer can be quite addictive! Never settle for "almost the right color" again. With UHT2: Ultimate Color, the possibilities are endless.
