2、s(默認(rèn)燈光 ):此項(xiàng)選定VR渲染是否MAX默認(rèn)燈光，通常情況下不勾選。Shadwos( 陰影 ):是否渲染產(chǎn)生陰影。Shadwos GL only( 只顯示全局光 )勾選直接光照將不包含在最終渲染圖像中。Materials(材質(zhì)組 )Reflection/refraction(反射/ 折射 )取消場(chǎng)景中VR 材質(zhì)不會(huì)產(chǎn)生光線的反射和折射。mplementation "five big development concept" of requirements,accurate grasp economic development new normal and transfo
