I have this very simple scene with a sky-sphere, directional light and atmospheric fog set up as lighting. The engine scalability is set to epic and there is no fps drop, but every texture doesn’t seem sharp and crisp. They look jagged and there is an odd blur and trail. Posting screenshots here.
Shot in the dark, have you tried different anti-aliasing methods?:
I tried FXAA and MSAA. MSAA was a huge performance loss even though it seemed like it worked better. FXAA on the other hand was no difference. But this may be a potential cause. I will look into it more.
Are you particularly thinking about the grass?
No not just the grass but everything on the scene.
Even the character itself is blurry even though it is from mixamo
So the problem was TAA as @ClockworkOcean had mentioned. But simply changing it to MSAA felt a bit unnecessary. So I found out a reddit link https://www.reddit.com/r/unrealengine/comments/6t5jnc/improving_temporal_aa/
Tampering with the values mentioned and adding a slight motion blur to the post processing volume seemed to fix the ghosting and blurry textures.
