經常遇到的問題,望各位能比下意見?? (關於Vray)

[Gattack]

本人工作上要用到3ds max既 Vray, 以下是小弟的一個job ref ,
因經常遇到的說話就系"點解咁暗" , "點解黑媽媽既" , 咁其實可以點樣系Vray到
set 到一D 燈光效果? 例如焗光, 凹入部分如何另佢光D 而唔會另到成個環境光曬
?

你可以加條 tube 喺D object 後面, 扮光管做 lighting, 當 wash wall light 咁做, material 方面就用 vray light material

There are 3 methods

1. F10>Indirect illumination>Secondary bounces
increase the Multiplier from 1.0 to 1.5 ....or more.

2. F10>Indirect illumination>Brute force GI>Secondary Bouces>
increase the value from 3.0 to more

3. reduce the opacity of shadow

the dark shadow is mainly caused by the lack of secondary bounce.
also, the shadow color of your key light is another issue

唔知你做既工作系咩呢? interior deign, 定系出效果圖 only?

我遇著呢D case 一定會幫客諗D 燈點擺, 如果直接同 designer 傾, 會問佢系咪冇比 light plan 定根本冇諗 lighting. 你去鋪頭見到咁大個櫃, 入面都會裝左唔同射燈 or wash light 啦.

比我裝燈既話, 上面 3個 box 後面會放光管, product 就唔好擺咁滿, 一來後面要留位比光, 二來太多 product 好似 supermarket 咁 (個客鍾意就冇計)

右面個玻璃櫃會裝盞射燈喺上面; 最下面有棵打橫既樹枝, 後面塊板可以用奶白色阿膠力板, 背面裝 LED 打光佢. 或者頂裝 tube light 都得

台面都好黑下, 個 material 系暗的話, 我地唔 prefer 放咁多 product 上去. 一系就裝多D 燈補光.

最後系個環境燈問題, 依家太 soft, 主燈唔夠強.... display 櫃通常都有幾支射燈射住, 我諗最好模擬番一間鋪頭既室內 lighting 比客睇, 咁先似 final outcome 個樣.
