[Image Removed]Hi，感谢用中文回复，我做了充分测试，r.Lumen.HardwareRayTracing.SurfaceCacheAlphaMasking 1很难察觉到变化，但是r.Lumen.ScreenProbeGather.ScreenTraces.HZBTraversal 0变化又太强，有时候美术只需要一个“表面缓存阴影透明度”的参数，最好针对这种过黑的Mask对象，开发逐对象和全局参数，逐对象的优先级高于全局，来实现我的截图中的A50%+B50%的效果，这种取巧方法是否会考虑？
Hi, thank you for replying in Chinese. After thorough testing, I found that r.Lumen.HardwareRayTracing.SurfaceCacheAlphaMasking 1 has a barely noticeable effect, while r.Lumen.ScreenProbeGather.ScreenTraces.HZBTraversal 0 is too strong. Sometimes, artists just need a “Surface Cache Shadow Transparency” parameter—ideally, both per-object and global settings—where the per-object setting takes precedence over the global one. This would allow adjusting overly dark masked objects to achieve the 50% A + 50% B effect shown in my screenshot. Would this kind of workaround be considered?
