在PlayerController下，调用DeprojectScreenPositionToWorld函数，只需传入屏幕位置参数，即可获取对应的世界位置与方向。实现原理：此函数内部涉及FSceneViewProjectionData结构数据，包括ViewOrigin、ViewRotationMatrix（旋转矩阵，不包含平移）以及ProjectionMatrix（投影矩阵）。通过求逆VP（视口）矩阵，实现从视口坐...

3.7、Ambient Occlusion开启之后,如果是动态光的情况下会消耗资源,开启AO后(Project Settings -> Rendering -> Default Settings ->Ambient Occlusion),引擎默认的AO为SSAO(Screen Space Ambient Occlusion), SSAO无法进行预计算,所以GPU性能开销较大,可以修改为DFAO(Distance Field Ambient Occlusion)以提升性能,因为DF...
1.在软件Project Settings里搜索planar,将support global clip plane for planar reflections勾选,启用平面反射。 2.在创建物体里找到Planar Reflection拖入场景中。将其属性中的show preview plane关掉。Normal distortion strength(法线扭曲强度)。Prefilter Roughness(预过滤粗糙度)。advanced-Screen Percentage(屏幕反射百分...
