标题: starterkit for beginner------Vray for Rhino render option
本教程转自官方论坛,详情请参考原帖:http://asgvis.com/index.php?opti ... =90&topic=631.0

首先说明这个教程的学习目的,(引用原文,实因本人晕文太晕:loveliness: )
the idea behind the starterkit is allways the same, new user should get fast start with one method based on light cache and irradiance map.

Starterkit 1 .. first version (HDRI env)
starterkit 2 ... update of the first version
starterkit 3 ... version based on physical sky
starterkit 4 ... new HDRI basd version with an experimental universal setup

由上可知共分为四阶段,下图是第一阶段的final render

场景测试原文件(rhino4.0),共3.76M,分七个包.

第一阶段作者原文引述:
Hi,

I have thought, I create a simple scene with all my favourit settings, good as start for beginners.
This scene base on Vlados unversal setting method with LC + QMC in a HDRI environment (two selfmade HDRIs from me). Facts:

- I use two HDRIs: one preblured for lighting and a sharp one for background. This help to get less noise in less time.
- I work in exponetial mode, this help to get an image like the human eye approx. works. The exponential mode is a little bit to soft, so most I correct it. A correction curve for the frame buffer is attched in the kit.
- The gold material is a double reflection layer metal for a subtle used metal effect. The blur layer need more time to calculate.
- For fast render tests use a QMC noise level of 0.05 and for less noise use 0.005. The rendertime from noise level 0.01 to 0.05 increase 100%.
Regards Micha

这里好像讲了渲染引擎的选择,主要参数的设置,GLOD材质的关键设置以及 A correction curve 的调节.
(场景里没有灯光,全用HDRI作照明)

在这里不明白他为什么要弄的这么blurry?
请教了!:)

晕了~~~~~~~大家可以到官网下场景文件嘛!不再发以后的文件了,
看一下第二阶段的效果图,DOF降低的100%,我喜欢:lol

大家对比一下,在对比中发现问题!:)

第二阶段是在第一阶段的场景文件上的设置更新,
更新内容如下:
Today I change from my first posted setup:
- gamma 2.2 output
- reinhard color mapping with burn 0.8
- LightCache set for glossy ray use, num. phases 2 (good for DualCore usage), adapt. sampling disabled
- secondary GI at 0.8
- camera aperture from 1 at 0.5 now (less DOF)
- HDRI more white balanced now
- camera center bias from 100 at 0.1
- gold material updated
- it's possibel to set the primary GI engine at IM or QMC, both are setuped (per default at fast IM)
- the starterkit contain a correction curve for the framebuffer that enhance the contrast and help to keep bright parts (can be optional loaded to the framebuffer curve control)

嘎嘎~~~~~~~~又是晕文~~~~:Q
这里主要说的是渲染设置的变化(肯定是和前面的对比了:) )
大家只要截图render option面板然后对比一下就明白他的意思了.

第三阶段final render 和原文件

PS: Current Problem: the blurry interreflections of the sun are very noisy.
(作者说这里最终渲染图有点小问题:) )

下面是对这个问题的讨论结果:
the sun reflections are a common problem in max as well. It has to do with the fact that the sun is very bright, so if the sun gets sampled, its weight in the sampling is so much that the pixel will be very bright. In max there is an option to switch of visibility, exactly to overcome this problem.

OK, so two options could be nice - a global disable visibility of the sun and a local version of the option (material or later object). For that example I would disable the sun for the checkerboard material only.

This should be the quality setup for every day, if speed isn't the first goal, but the rendering shouldn't be slow. Some hints explain, how to speed up the rendering. The first goal of the setup is quality, so that beginners must not post blotchy images anymore.
(这段说的是渲染品质与速度的关系,鱼和熊掌是否兼得得看你的本事了:lol )
My last experiments for quality show me, that the image sampler "adaptive QMC" is important for the overall quality, for blury effects and small details. So, my tests show me, that I can use high material subdivs, but without a high AQMC, the image quality dosn't increase. So, the new setup base on image sampler "adaptive QMC" 1/32. For more speed try lower values like 1/16, 1/8 or 1/4.
The noise threshhold of the QMC sampler deteminate the quality level - 0.01 is good, 0.005 very good and 0.02 is good for fast previews. It's seems to be, that material subdivs can be ignored, but if a blury material looks noise, it can be used to increase the local quality.

Global Illumination: I try to keep it simple and fast. Some little rules:
- less shadow details and more speed -> max IM rate at -1 (default 0 high quality)
- blotchy image -> set more IM subdivs (good for interiors)
- more speed -> try less IM subdivs until light blochtes are visible

Light cache for secondary GI is good for anything. I don't know any reason to dosn't use it allways. Subdivs are default at 1200, less can speed up the LC pass, more can increase the quality. But 1200 should be good for most cases, the LC pass is fast. Sample size 0.01 is a good medium value, for more little GI shadow details a smaller value can be used. LC option "use for glossy rays" is a speed up for reflections. If reflections show blotches, use more LC subdivs or set the filter values higher (for example 20 ... 50).
(上面三段说的是渲染设置,你们的英语比我好,不说了:( )
这是作者介绍的一点设置心得吧,多看有益:)
