犀牛产品渲染场景实例及说明

犀牛产品渲染场景实例及说明 产品渲染场景实例及说明【原创教程】 论坛里有很多朋友对于渲染已经有了基本的知识，能够做出自己的效果图来了 但是在效果上总不能使自己满意，比如出现“颜色太均匀”“没有层次感”“曝光”等问题 想要说的是，一张好的成品效果图是材质，灯光和环境的综合 表 关于同志近三年现实表现材料材料类招标技术评分表图表与交易pdf视力表打印pdf用图表说话 pdf 现，材质只是渲染技术的一部分~ 这也就就是为什么有的朋友下载了现成的材质，而自己渲染却没有效果的原因 斗胆把自己以前做的一个小玩意拿出来当作例子，结合灯光和环境，希望能给大家些帮助~ 如有任何疏漏和错误，欢迎大家提出和讨论～转帖请注名出处～ 场景布置~如图所示 大家注意到，效果图中的高光亮斑。这种效果正是由两个区域灯光形成的。 一般来说我习惯在场景中放置两个灯光(基本满足简单产品的表现)，分为主灯和辅助灯(自己命名的~) 主灯往往比辅助灯“强”一些，这个“强”体现在亮度，与产品之间的距离，灯的大小和颜色等几个方面 之所以这丫那个做目的是模拟真实的场景: 试想一下，白天的一间屋子里，可以认为存在两个光源，一个是窗户直接透进来的天光， 另一个就是室内墙壁天花板等的漫反射，这二者一强一弱，正好对应我们渲染场景中的主灯和辅助灯。 atmospheric pressure vessel 4 GB50231-2009 mechanical equipment installation engineering construction and acceptance specification for 5 GB50275-98 compressor, fan and pump installation engineering construction and acceptance specification for lifting 6 HG20201-2000 construction installation engineering construction standard 7, HG ...

(7) at height and the opening and provisional protective measures have been taken, the responsible unit fined 200 Yuan, construction person in charge a fine of 50 Yuan. (8) no permit to work and the job in accordance with the provisions, on the job unit fined 300 yuan, the unit will charge a fine of 100 Yuan. 7.5.3 accident penalties (1) injuries fatalities directly punished 1~2 million. Direct responsibility for the accident and have the corresponding responsibility of leadership, such as concerning administrative sanctions, should be brought to the company or the relevant Department. (2) personal injury accident occurred, the direct punishment 0.5-10,000 yuan, responsible for the direct responsibility for the accident and the responsibility of leadership, such as concerning administrative sanctions should be dealt with by the personnel Department of the company.
