Hey Andrew, thanks for your help.
I checked your suggestions and everything was setup right. The camera actor was set to Temporal AA. What do you mean with render individual frames in matinee? I can only select to render as avi or still images (as in your rollout image). There’s no Option to say: render frame 350 to 800 or something like that.
After a little research, i guess i can break down the problem: First, it is a bad idea to make meshes with absolut sharp edges (Walls ect.). They should be roundet at the edges, or even just cut with a little surface that brakes the edge from 90 degrees to 45 degree. The second thing is to avoid little overlapping parts (like the roof in my image) which causes tiny shadows.
The same thing with the border at the street. This boarder creates a sharp shadow from aprox. 20 centimeters. when watched from far away, this is so tiny that aliasing occurs. I have read in the “ray traced distance field soft shadows” Documentation, that jaggies can occur in temporal AA. I guess this is the case in my project. The only strange thing is, that Temporal AA does a great job when the camera is not moving.
When i move in the editor or in game, alias comes out (not everywhere! just on sharp edges…), and after standing still, the image get polished with sharp edges. This can take sometimes a second or two. The Editor is set to EPIC in all sections and runs at 50fps…Maybe this is a gfx card issue? Super AA from the gfx Card?
I have watched the videos from koola and others, and there is absolut no alias visible, but they also don’t use absolut sharp edges in their models. I will perform a test with sharp edged and smooth edged cubes and then lets see, if that has an impact. Thanks
