1、要的就是免费第一课:VRay的安装和操作流程一、Vray的安装二、Vray的简介:VRay是由著名的3DS max的插件提供商 Chaos group推出的一款较小,但功能却十分强大的 渲染器插件。VRay是目前最优秀的渲染插件之一,尤其在室内外效果图制作中,vray几乎可以称得上是速度最快、渲染效果极好的渲染软件精品。随着 vray的不断升级和完善,在越来越多的效果图实 例中向人们证实了自己强大的功能。VRay主要用于渲染一些特殊的效果,如次表面散射、光迹追踪、焦散、全局照明等。可用 于建筑设计、灯光设计、展示设计、动画渲染等多个领域VRay渲染器有 Basic Package和 Advan

2、ced Package两种包装形式。 Basic Package具有适当 的功能和较低的价格,适合学生和业余艺术家使用。Advanced Package包含有几种特殊功能,适用于专业人员使用。以下是Vray的作品欣赏三、Vray的工作流程1创建或者打开一个场景2指定VRay渲染器3设置材质4把渲染器选项卡设置成测试阶段的参数:把图像采样器改为“固定模式“,把抗锯齿系数调低,并关闭材质反射、折射和默认灯。勾选GI,将“首次反射调整为 lrradiance map模式(发光贴图模式)调整min rate(最小采样)和max rate(最大采样)为-6, -5,同时“二次反射调整为QMC准蒙特卡洛算

3、法或light cache灯光缓冲模式,降低细分。5根据场景布置相应的灯光。开始布光时,从天光开始,然后逐步增加灯光,大体顺序为:天光-阳光-人工装饰光ew 一 tome wok, t he coulleto tae resollbH. n n I to ell e dnc.Gommllt a ndK.llls t I t (r g li IL mi oil, Hile ly msl an s of Hlal on Mie is to n n chan of slli I n -gmli urnn n party K- Hili c, ope - widely a ccepspervn by

12、好 的和正确的照明(能量分布),更快的渲染,更方便控制的反射和折射参数。在 VRayMtl里你能够应用不 同的纹理贴图,更好的控制反射和折射,添加 bump (凹凸贴图)和 displacement (位移贴图),促 使直接GI(direct GI)计算,对于材质的着色方式可以选择BRDF (毕奥定向反射分配函数)。详细如下:Basic parameters(基本参数)Diffuse (漫射)-材质的漫反射颜色。你能够在纹理贴图部分( texture maps) 的漫反射贴图通道凹槽里使用一个贴图替换这个倍增器的值。Reflec t (反射)-一个反射倍增器(通过颜色来控制反射,折射的值)。你

21、意味着得到非常模糊的反射效果。值为1.0,将关掉光泽度(VRay将产生非常明显的完全反射)。注意:打开光泽度(glossiness)将增加渲染时间。Subdivs (细分)-控制光线的数量,作出有光泽的反射估算。当光泽度(Glossiness)值为1.0时,这个细分值会失去作用(VRay不会发射光线去估算光泽度)。Fresnel reflection (菲涅尔反射)-当这个选项给打开时,反射将具有真实世界的玻璃反射。这意味着当角度在光线和表面法线之间角度值接近0度时,反射将衰减(当光线几乎平行于表面时,反射可见性最大。当光线垂直于表面时几乎没反射发生。Max depth (最大深度)-光线跟踪

22、贴图的最大深度。光线跟踪更大的深度时贴图将返回黑 色(左边的黑块)。Use interpolation (使用插值)-当勾选该选项时,VRay能够使用一种类似发光贴图的缓存 方式来加速模糊折射的计算速度。Exit color (退出颜色)-当光线在场景中反射次数达到定义的最大深度值以后,就会停止 反射,此时该颜色将被返回,更不会继续追踪远处的光线。Refract (折射)-一个折射倍增器。你能够在纹理贴图部分( texture maps)的折射贴图通道 凹槽里使用一个贴图替换这个倍增器的值。Glossiness (光泽度)-这个值表示材质的光泽度大小。值为0.0意味着得到非常模糊的折射效果。值

32、)-当勾选该选项时,VRay能够使用一种类似发光贴图的缓存 方式来加速模糊折射的计算速度。Affect shadows (影响阴影)-用于控制物体产生透明阴影,透明阴影的颜色取决于折射颜 色和雾颜色,仅支持 VRay灯光和Vary灯光阴影类型。Affect alpha (影响alpha)-勾选后会影响 alpha通道效果。、各种常用材质的调整1、亮光木材:漫射:贴图反射:35灰 高光:0.8亚光木材:漫射:贴图 反射:35灰 高光:0.8 光泽(模糊):0.852、镜面不锈钢:漫射:黑色反射:255灰. wok, ti.moe hone sty i 10als Thi亚面不锈钢:漫射:黑色拉丝

49、减。(这是真实世界灯光的衰减方式)存储发光贴图-当该选项选中并且全局照明设定为Irradiance map时,VRay将再次计算VrayLight的效果并且将其存储到光照贴图中。其结果是光照贴图的计算会变得更慢,但是渲染时间会减少。你还可以将光照贴图保存下来稍后再次使用。影响漫射-控制灯光是否影响物体的漫反射,一般是打开的影响镜面-控制灯光是否影响物体的镜面反射,一般是打开的细分-该值控制VRay用于计算照明的采样点的数量,值越大,阴影越细腻,渲染时间 越长。阴影偏移-控制阴影的偏移值。ew 一 tome wok, t he coulleto tae re sollbH . n n I to

58、时,VRay会忽略MAX的物体阴影参数 (颜色、密度、贴图),此时来看透明物体的阴影颜色将 是正确的。取消选择该复选框后, 将考虑灯光中物体参数的设置,但是来自透明物体的阴影颜色也将变成单色。光滑表面阴影:选中后,Vray将在低面数的多边形表面产生更平滑的阴影。偏移-某一给定点的光线追踪阴影偏区域阴影-打开或关闭面阴影。立方体-VRay计算阴影时,假定光线是由一个立方体发出的。球体-VRay计算阴影时,假定光线是由一个球体发出的。U尺寸-当计算面阴影时,光源的 U尺寸。(如果光源是球形的话,该尺寸等于该球形 的半径)V尺寸-当计算面阴影时,光源的 V尺寸。(如果选择球形光源的话,该选项无效)W

59、尺寸-当计算面阴影时,光源的 W尺寸。(如果选择球形光源的话,该选项无效)细分-该值用于控制 VRay在计算某一点的阴影时,采样点的数量。三、VRay阳光激活-阳光的开关浊度-设置空气的混浊度,值越大,空气越不透明,光线会越暗,色调会变暖。早晨和 黄昏的混浊主度较大,中午混浊度较低。有效值为2 20。臭氧-设置臭氧层的稀薄程度,值越小,臭氧层越稀薄,到达地面的光能越多,光的漫 射效果ew 一 tome wok, t he coulleto tae re sollbH. n n I to ell e dnc.Gommllt a ndK. llls t I t (regli IL mi oil,
