yea that was just an example, but lets say i do want perfectly smooth floor thats reflecting stuff around it without artifacts, which is not possible with ssr, no matter how high the settings are. (although in 90% of cases i would use it for mirrors and flat glass planes)
my problem with this is that its not anything fancy, its not voxel based gi, or self shadowed paralax mapping.
its a simple planar reflection actor that existed in udk and even in games 15 years ago, and yet its missing from UE4? why’s that ?
