2、s:材質(zhì)reflection、refraction:反射、折射反射跟折射的總開關(guān),取消所有物體的反射和折射都會消失maxdepth：最大深度指限制材質(zhì)反射和折射的最大反彈次數(shù),數(shù)值越高,渲染越慢.一般是在材質(zhì)球進行單獨調(diào)節(jié),不會在此進行統(tǒng)一的限制maxtransp.levels:限制透明材質(zhì)被光線追蹤最大深度.值越高被光線追蹤就會越深,效果會越好,但渲染相對會越慢tansp.cutoff:限制VR寸透明板材質(zhì)光線追蹤的終止值.保持默認(rèn)即可maps:貼圖取消勾選在渲染時看不到貼圖,一般選擇勾選filltermaps:勾選那么使用VRi身抗鋸齒進行過濾.不勾選那么以原始圖像渲染.filtermap

3、sforGi:Glossyeffects:是否翻開模糊效果,如不勾選場景里所有反射和折射將沒有模糊效果.一般默認(rèn)勾選.overridematerials:代替材質(zhì)勾選后可以在旁邊的按鈕參加一種材質(zhì),此材質(zhì)代替場景里所有的材質(zhì).有利在測試燈光時提升渲染速度overridecolor覆蓋顏色uninvertednormalbumpassettransferSystem系統(tǒng)設(shè)置RaycasterParams光線追蹤參數(shù)MaxDepth最大深度60MinLeaf最小樹葉0Face/Level面/級2MemLimit限制400DistributedRendering分布式渲染設(shè)置DistributedR
