Vray can achieve this kind of effect ?

[aniOcean1204]

Recently, I wanna to make a slow motion aesthetic animation in 3ds max by vray. I am new in this field and start learning Vray a couples of months ago.

Last week, I saw an animation and it really inspires me.

http://www.vimeo.com/5115304

This one is superb. I am planning to do slow motion movie like this though it is not easy for a beginner like me. I wanna to seek advices here.

Can above movie completely done by 3ds max or it is just film by an camera?

I tried to sth like that with DOF in 3ds max b4 but it took an age to complete with 1 frame. And if I want to make an animation with 10 -15 seconds, I believe it is not a good way for me to complete.

any hints for that would be appreciated

用比較"平"既方法最好就系 compositing 到做, 3d 要 render 一個 depth layer, 然後 comp 用 lens blur 一類既 filter, 咁就可以控制 blur 前 or 後, 當然個效果冇 3d 做咁靚, 但時間慳唔少.

另一個方法就會應用去某d 角度既畫面, 例如片入面你見到一排排既相, 咁我地會分開前中後景 render, 然後 comp 到 tune 番唔同 layers blur 多少.

thanks, h2O, good to see your quick reply, think I got some ideas now. I know what you means in the second point. But in the first point, do u mean render a nice image in 3ds maxand then use the blur effects in AE for the composition?

This is the image reference with nice DOF which I found useful for my practise

[aniOcean1204]

I tried to render a still image first to see how the lighting and material come up. (It takes long time to learn each setting in vray for the beginner)


Testing 1


Testing 2
Use falloff for the reflection


Render the image and use it as the reflection for the black key. But it looks a bit fake for the same reflection on every keys




I found hard to have a good result on the reflection of black and white key. And the HDRI reflection of the side view look a bit fake too.

點樣render 個 depth layer

[aniOcean1204]

I added some light for specular part aorund the black keys, it is hard to render sth like the reference.

Depth layer 有兩種, 真 or 假

真既系指 zdepth.... vray or max 點做要你自己搵下資料, 因為我唔識 max

假 depth 就系一個 黑到白既 gradient, 由個 top view project 落去, 出黎既效果就好似 fog 咁


Shader 方面

呢種 material 最好跟番現實一樣有 Fresnel reflection, 我唔記得個做法系咪 reflection 度要有 fall off map, 之後先可以著 Fresnel 呢個 option


Lighting

你見到個 piano 既 highlight 其實都系 reflection, 只要你放塊白色既板做 reflection, 放啱個位置就會出到一條白邊咁樣既 highlight

hdr 圖同你個 reference 既 lighting setup 都唔同, 你唔一定要用 hdri, 你自己 setup 個 env 做 lighting 一樣都系 high dynamic range

我唔知你呢張 reference 邊到黎, 但我估影相既時候, 後面系有窗口 or soft light. 其他 detail 位黑哂睇唔到, 有可能屋企影之後 tune 黑, 亦有可能系 studio 周圍黑哂, 靠自己打燈. 個 highlight 上面有一點 bloom 既光點, 一系窗口既太陽, 一系soft light 中間個點光位.

點樣render 個 depth layer

there are two ways to do Z depth /depth layer in 3ds max.

1.

F10> Render Setting> Render Element> Press"Add"> choose "Z Depth"> go to Z Depth Element Parameters on the bottom of this window> Set the correct parameters for the Z depth boundary.

e.g. Zmin: 100, Zmax: 300,
the parameter is relating to your scene scale.



2.

Render rla.format , you can get the Z depth in AE also.


finally, you can do a 2d DOF in AE from those Z depth.
1st method can get a better quality of depth layer.

what i suggest is to use Default material. It has a specular control for your material. Default material also can use vray reflection parametar.

also,you can add a gradient relfection/soft reflection box on the top of your scene. try to achieve this sort of reflection.

and try to render different kind of reflections, then you can mask some specific areas for you reflection.

[aniOcean1204]

thanks for every big big friendly advice.

There are some parts especially the reflection box I dont know.

About reflection box, can anyone explain a bit more about that? I bought a few books and searched for the internet and cant find a related articles about that. Is it simply a box and add the gradient on the material?

from h2o saying, 你見到個 piano 既 highlight 其實都系 reflection, 只要你放塊白色既板做 reflection, 放啱個位置就會出到一條白邊咁樣既 highlight

is that a reflection box too? If i put it near the black keys, how can that be invisible when I render it in my camera?

呢個系 maya mentalray tutorial, 都可以參考下既

加左hdri做environment. 感覺好似好左. 有d反光部分都系差左d

真系好正, 最衰我唔識maya, 不過學到好多有用的 concept, 謝謝

差唔多既野...你可以跟住h20個tutorial照做..max都系用d咁既方法

Thanks for the reply again.

These days, I found some problems about Max 9.

Once I found 6*4 dimension of material balls in material editor . I wonder whether I can increase the number of those when I found 24 materials which is not enough for me to use?

And when I render in Max, can I just render one small part of the picture rather than rendering the whole picture if I just wanna to see a small part of image?

The last question is that the difference of 3ds max 64bit and 32bit.
I may change to window 7 soon so I wonder whether it will be better to use 64bit 3ds max. Will 3ds max compatible and run faster in 64bits with 4G RAM?
