Totally beautiful… As for your questions:
“4) About metallic values in material. Somewhere on the forum I read that the value of this parameter must be 1 or 0 and can not be in between. It’s true? As for me it is strange, there are materials that emit metal and there is appropriate to do other values …”
I think metallic in the material is between 0 and 1, can be 0.2, 0.4 etc.
“7) Very long calculate of production quality - about 30-40 minutes. Or is it normal for the scene? Scene have a LightmassImportanceVolume and PostProcessVolume. All big surface has a light map res - 2048…I show the settings, may be it can help.”
What Lightmass settings are you using?
“8) When I do the High Resolution Screenshot in final image the decreases quality. Why is this happening?”
I notice this sometimes, try doing a “Simulate” so the playback is simulated but you can still take a high-res screenshot.
“1) r.SSR.Quality 4 is help but not enuff…there is still a lot of noise, especially when the camera moves;”
You definitely have to edit the shader if you want the best SSR: 3D Modeling & Texturing: [Unreal Engine 4] Improving Screen Space Reflections
“3) Anti-aliasing. Bad result is already in the final sequence from the Matinee :(. In the viewport anti-aliasing is good.”
That’s strange. Could be Post Process Volumes overriding one another? Check Post Process Volume priorities.
