Renderman Studio 近日發佈了功能更加強大的 RenderMan Studio,更有助於製作逼真CG圖形圖像,同時,也為眾多藝術家提供了便捷的線性工作流程。所以,RenderMan Studio 比之前更加強大易用。
RenderMan Studio 是 Pixar的一套針對Maya用戶的材質和燈光工具,其中包括如下要素:
- 對 Maya的貢獻 - RenderMan強大功能適用於Maya工作流
- Slim - 強大的視覺材質球編寫處理
- “it” - 圖像流覽器、可編寫腳本的合成器
- Pixar's RenderMan - 具有最新技術的嵌入式渲染器
- LocalQueue - 局部渲染管理
- Tractor - 渲染場的管理解決方案
路徑跟蹤加速渲染
RenderMan Studio現在支援路徑跟蹤加速渲染。新的材質和燈光工作流。RenderMan Studio優化燈光場景,流程更快更直觀。
幾何區域燈光
支援任何原始幾何圖形轉換成體積區域光源。這些不但高度逼真,而且可以創建大量複雜燈光特效,幾何區域光為燈光師提供了叫做unified sampling"的屬性,更便於操作。與常規區域燈光相比,它們更簡單快捷。
RenderMan Studio現在具有RFM和Slim的體積區域光。支援功能如下:
- 所有燈光類型: Distant, Spot, Rectangular, Disk, Sphere, Cylinder
- 放射幾何體: 現在幾何體的任意區域都可以用作區域光
- 體積區域光遮擋
- 更便捷的燈光設置、渲染加速
主光面板
主光面板是一種新的燈光面板,它用於控制場景燈光,易於操作。並且,它對重新渲染非常實用。這個主光面板可以同時調節多個燈光,同時,也可以通過創建標籤來保存燈光設置。並且,對於每一個單獨燈光的調節都可以快速預覽效果。
為協助合成工作流程,AOVs現在可以針對單獨燈光輸出。這個新功能同時也支援燈光組,它的出現進一步完善RenderMan Studio燈光系統。
優化的次表面散射
創建逼真人體皮膚一直是一大難題,後期結果取決於次表面散射運算。RPS通過提供次表面散射光束效果,可以更好地創建逼真人體皮膚。這只比常規SSS 稍微繁瑣。但它為我們提供更令人滿意的效果,並且在做動畫時更加穩定。這樣,我們創建的人物角色就更加真實,而不是類似於石蠟效果了。
在RFM和Slim中的材質球圖庫支援改進的光束次表面漫反射技術,這有助於創建更好的人體皮膚以及其他特效。
物體替代
新的RenderMan Studio通過常規Maya物體替代工作流程支援物體替代,這大大提高渲染大的光線跟蹤場景的效率。
改進的體積功能
優化的Renderman體積處理功能。由於場景中接近攝像機的區域採樣不像場景中其他元素一樣多量採樣。無論場景需要多大的體積感,無論你什麼時候需要攝像機和爆炸以及龍捲風互相協作,所需的效果都能夠實現。
優化的Ploygon
完善了的幾何體mesh,大大降低了記憶體要求。基於場景,渲染複雜的幾何體mesh時,用戶可以減小所占記憶體。新功能在置換貼圖情況下,速度比之前提升2-3倍,在沒有置換貼圖情況下,速度比之前提升20%-35%。
其他功能
- 幾何體mesh記憶體大大提升
- 新的海洋材質
- 用於合成時捕捉陰影的HoldOut材質球屬性
- 改進的圖像處理工具“it”,速度更快,功能更加強大
- 新的材質球功能,可以將一個單獨材質用於多個材質的上一層。
Pixar's Tractor 管理最困難的渲染
Tractor 是一種現代且強大的網路渲染解決方案,能夠擴展到最大的渲染農場。他並不侷限於只渲染 RenderMan,Tractor可以輕鬆地被用來從各種來源分配網路任務,成為一個中央生產工作分配系統。
Tractor is designed to be a compact system, relative to the complex role that it plays:
- Tractor-Engine: The central job queue manager, a self-contained single install. Low overhead operation with engineering emphasis on high throughput job distribution for large farms.
- Tractor-Blade: Simplified "plug-and-play" deployment of new execution servers on any size farm.
- Tractor-Dashboard Web UI for ubiquitous access to job feedback and farm status.
- Scripting and command-line tools for wranglers and advanced users.
- Component architecture based on common web technologies.
Cross Platform and Web Based
Tractor is packaged for each operating system, containing all of the Tractor components you will need, though each machine may only use a subset
Tractor Components
Tractor-Engine The heart of it all
Tractor-Engine maintains the central job queue and dispatches tasks.
Tractor-Blade For Render blades
Tractor-Blade is aPython based execution server running on each remote node.
Tractor-Dashboard The Control Center
Tractor-Dashboard is a customizable web browser user interface providing centralized control of all render jobs.
Highlights
– Powerful scripting interfaces
– Native Maya Integration
– Flexible resource-sharing controls
– Python module extensions
– Minimal computational footprint
– Streamlined installation
– Directory Mapping across Different OS
– Major user interface enhancements
– Open web standards
– HTML 5 support
– Can bridge to any application
