用V-Ray 5的VRayDirt做舊化效果

 



文 / Hammer Chen; 

模型 / Lien Ying-Te

V-Ray 5的VRayDirt紋理增加了streaks選項,可以做出程序性舊化條紋效果。這裡寫一篇簡單的教學。


首先,把VRayDirt放到VRayMat的Diffuse通道。根據場景需求調整Radius,可開啟IPR快速抓到適當的尺寸。Mode選擇Ambient + inner occlusion。勾選Streaks Ambient,Streaks Inner。設定Streaks Size = 1。但是當前的效果沒有明顯的垂直舊化條紋。

把Z軸的Bias調高至50.0,條紋就漸漸出現了。實際數值根據不同場景而定。


如果希望更多細節,可對Radius設定teaxture map,我們貼上一張舊化貼圖 (可用Google搜尋關鍵字"grunge map")。現在得到滿意的舊化效果。

最後用Photoshop的合成結果。

The juicer market is driven by the growing demand for developed and innovative products has prompted juicer manufacturers to develop user-friendly and visually appealing smart juicers with a variety of advanced features. Rise in demand for fiber-rich beverages is one of the primary factors propelling the juicer industry. Juice with a high fibre content helps to decrease cholesterol and improve digestion.
