Hello all. I’m just giving some of the editors more detailed features a once over and I want to ask some noobish questions.
Firstly, antialiasing. In the project settings, under rendering, there is an option to choose between Temporal AA and FXAA. Looking for the first option online tells me that it seems to be an Nvidia technique. I take it this means it doesn’t run very well with AMD? This is a shame, because the image results show it is vastly superior to FXAA. Can anyone tell me how well it works with AMD cards?
Lastly, ambient occlusion, something I know very little about. When playing around with the editor, I notice that AO is being collected in the corners of the room I have set up. I always thought that AO was something that had to be baked. How is UE4 creating AO at runtime? Is it very high in render cost? Does it mean that I don’t have to bake out AO maps for high-poly meshes with normal maps and such? And how do I switch it off and on?
Thanks in advance for any answers.
