最全草图大师vray0渲染器中英对照及各种材质参数设置

1、GlobalSwitches全局光照开关设置Geometry:几何体通用的参数Displacement:置换勾选后使用VRB带的置换,到不会影响MA自带的置换,不勾选VR勺置换将不起作用.一般会选择勾选Forcebackfaceculling:强制反面消隐如勾选渲染时不显示模型的反面,一般很少会勾选lighting:灯光lights:灯光灯光的总开关,不包括默认灯光,一般勾选defaultlights:默认灯光一般在布置灯光是取消勾选hiddenlight:隐藏灯光勾选会渲染隐藏的灯光,一般勾选shadows:阴影为复原真实的物理现象,一般会勾选showGIonly:只显示GImaterial

2、s:材质reflection、refraction:反射、折射反射跟折射的总开关,取消所有物体的反射和折射都会消失maxdepth：最大深度指限制材质反射和折射的最大反弹次数,数值越高,渲染越慢.一般是在材质球进行单独调节,不会在此进行统一的限制maxtransp.levels:限制透明材质被光线追踪最大深度.值越高被光线追踪就会越深,效果会越好,但渲染相对会越慢tansp.cutoff:限制VR寸透明板材质光线追踪的终止值.保持默认即可maps:贴图取消勾选在渲染时看不到贴图,一般选择勾选filltermaps:勾选那么使用VRi身抗锯齿进行过滤.不勾选那么以原始图像渲染.filtermap

3、sforGi:Glossyeffects:是否翻开模糊效果,如不勾选场景里所有反射和折射将没有模糊效果.一般默认勾选.overridematerials:代替材质勾选后可以在旁边的按钮参加一种材质,此材质代替场景里所有的材质.有利在测试灯光时提升渲染速度overridecolor覆盖颜色uninvertednormalbumpassettransferSystem系统设置RaycasterParams光线追踪参数MaxDepth最大深度60MinLeaf最小树叶0Face/Level面/级2MemLimit限制400DistributedRendering分布式渲染设置DistributedR
