Strange blur effect on edges. Maybe FXAA?


(Cryunreal) #1

I see that you made temporal antialiasing when the camera stops. But i think you dont turn off FXAA. TAA (or real supersample AA) + FXAA = BLUR EFFECT. You need to turn off FXAA when camera stops.)

You are right, it's the FXAA.


(no fxaa on the right)

Althought the crown and ear edges are a bit aliased, we can see that the fxaa kind of blur everything (wrinkles, eye reflection halo, nose).

When you turn off fxaa? It is really important.


(Paul Sketch) #4

Yes, already under investigation

We are working on a fix, we'll ping you back when it'll be live.


(Cryunreal) #6

I very happy that sketchfab has good support. I think that i can help you as technical 3d artist later.)


(Bart) #7

You can :smile:

I am sorry... I would like to work in your company, but i am working in Unigine as Lead 3D Artist and Technical 3d Artist and i like my job))). By the way I met with you on Siggraph 2015. But if you need to help, you can contact with me.

Updated the AA code, tell us if you still find strange artifacts or anything. Thanks


(Cryunreal) #10

I am sorry for so slowly feedback...
Yes, i see the problem with AA.

i have attached screenshoot.
It is very important for art with lot of flickers and lines. It just imortant for everything!))


(Cryunreal) #11

i think you need to increase angle of camera jitter, but very accurate... or you will get bad smooth effect)


(Paul Sketch) #12

Hard to say on that model, as it's heavily postprocessed, the sharpen doesn't help, and those postproc can alter the AA in way we cannot prevent.


(Cryunreal) #13

How many frames do you accumulate for TAA? And what the type of jitter do you use?


(Paul Sketch) #14

32 jitter using halton
( only static TAA on static frame )


(Stephomi) #15

By the way, there's a bug that prevents the TAA to be triggered sometimes (since 2-3 weeks).
It will be fixed on the next release.

As @paul_sketch stated, a model without sharpen (or postprocess) would make more sense for us to detect caveats.


(Cryunreal) #16

Yes, halton is the best jitter for TAA. 32 samples should be enough... Really Strange... :neutral_face:

Thank you! I will wait this fix)
