What would be the best way to avoid or reduce the moiré pattern effect I get in my architectural animation (especially masonry).
I have already reduced texture size, turned mipmap off, AA to med Mitchell ...
And I'm also looking into getting rid of the flickering and 'crawling textures' (grass, trees, pavement). Any ideas on that are welcome too.

Fine/dotty/grid details require alot of AA. When i get home im gonna test if Fullscreen Grid AA is the best or if i can do something else like increasing AA pixel area/thickness. Right now i dont know.

Try a box or cone filter with a larger filter radius (1.5 or more) this will make the images less sharp but will also help reduce the artifacts.

Adding motion blur helps too but takes a bit more time to render. You could also try adding MB in post though.

Why would you turn OFF mipmapping? The mipmapping is there to help reduce moiré in image maps!

page 17 of the holy scroll:

Mipmaping is used in Lightwave to anti-alias textures to prevent “crawling” textures inanimations. This produces quite blurry textures since Kray renders quite strong mipmapping. So make sure mipmapping is OFF for your textures. This is especially important for Bump channel
where mipmapping may diminish effect of bump map completely.

hmm that was very true one period, having mipmapping on made everything more blurry than it should be. But now it's better. For stills, it is still advised that it is off, but you should turn it on for animations.

Thanks for all the replies, now finding the time to test it all

Btw where did I read that mipmap had to be turned off? Sure it was on this forum. There was even a plugin that could remove mipmapping from all surfaces...?? Or was that only for stills?

What about pixel blending? on or off?

What would be best settings for a small Motion Blur ...

For small Mblur i would try with Fullscreen grid 2-3, spline pixelfilter and limitdr -1; to compress dynamics for the brightest stuff like luminous surfaces.

It seems FSAA is required to render MB. Isn't this way slower?

indeed FullScreen is slower than adaptive but that's how Kray calculates DOF/Mblur.

Gonna test rendertimes now to see if MB is better done in Post

How can you do Mblur in post? Please explain if you have an alterantive solution.

Silverw, it's doable if you can export motion vectors and use something like Reelsmart Motion Blur, or some compositing package that natively supports such function (I think the new fusion does it?). It's not perfect and can have strange results in overly complex shots, but generally it's very usable.

What does limitdr -1 exactly mean?

edit:
didn't search the forum limitdr: Limit dynamic range to force luminous surfaces to not cause bright splotches in irradiancemap.
