Iray 自然材质包 - 树皮材质

Iray自然材质 —— 树皮材质是一款出色的材质包，内含20种树皮材质，均取自真实照片，并配有法线、置换和光谱映射功能，可应用于任何需要添加树皮材质的模型！ 其中一些优质材质预设还包含苔藓和地衣图层，细节更加丰富！ 这款材质包专为给我的自制运行时中的老旧树木模型重新赋予纹理而设计，与我的一些树木和灌木相匹配。材质包包含两套树皮材质，一套是纯色材质，另一套在纹理预设中添加了苔藓图层（两套材质预设的缩放工具也略有不同）。 只需选择你想添加树皮材质的对象，确保选中特定表面，然后添加材质，再转到缩放工具中选择合适的选项即可（许多模型具有不同的UV映射，因此存在不同的比例来应对这一问题。如果没有你需要的比例，你可以随时转到材质选项卡，根据自己的喜好设置贴图大小，可能需要进行一些试验）。 所有材质都具有高水平的置换效果，并设置为与子分割配合使用（如果你的模型尚未启用子分割，你可以在Studio中将其转换为子分割模式）。这增强了材质的真实感，能让原本平淡的表面焕发生机。 总之，这款材质包是材质库中的宝贵资源，它能为你添加与我在Daz 3D商店中出售的许多树木和灌木相匹配的逼真树皮材质，让你能够将其他物品无缝融入你正在创作的场景中

Iray Nature Shaders - Bark is a great bundle of 20 bark shaders for Iray, all taken from photographs and furnished with normal, displacement and spectral mapping, which can be applied to any item you wish to cover in bark! Some of these great shader pre-sets include layers of moss and lichen for even more detail! Designed to re texture older tree models in my own runtime, to match in with some of my trees and shrubs, the bundle comes with two sets of bark shaders, one plain and one with added moss layers in the texture pre-set (Along with scaling utilities for each of the two sets as they work slightly differently). Just select the object you wish to add the bark shader too, make sure the specific surface is selected and add the shader, then go to the scale utilities and pick one that works (many models have different UV mapping so there are different ratios to help with this. If there isnt the ratio you need you can always go to the shader tab and set the tiling to your liking there - some experimentation may be needed). All of the shaders have high levels of displacement and are set to work with subdivision (you can convert your model to sub division inside studio if it is not already sub d). This adds to the realism of the shader and can breathe life in to an other wise flat surface. All in all this is a great asset to have in your shader collection, adding realistic bark materials that match many of the trees and shrubs you will find in my Daz 3D store, thus enabling you to blend other items in to the scene you are creating seamlessly!
