hi !

i am helping a friend with some architectural pictures, rendered in Advanced Render in cinema.
we have some hires textures (8 x 6 K) that are totally sharp. but when rendering, some tiny annoying flickering appears in the rendering that looks like the wood in the facade was cut extremely rough. or some high-frequency color errors...

has anyone an idea how to solve this ?

i have pretty good render settings with GI.

Have you tried the texture sampling options (Alias 1..3, MIP, SAT)? And increasing anti-alias Min Level in the render settings?

hi !

i got a tip yesterday about AA. i used cinema a lot years ago, but i forgot to set the AA from "geometry" to "best". but it's not perfect yet.

the sampling options are a little mysterium, but i'll check them out and find one that is better. it's on MIP now.

(i tried to set the overall AA from still image to catmull or similar before, but that didn't help... )

thanks for the hints btw !
let me try ..

It's been a long time since I used Cinema for anything just remotely serious, so this is just a guess too: If your textures or of such high resolution, how about scaling them down manually before? If your images are 2k x1.5k, then any texture above even that resolution surely just eats up resources that will not contribute to image quality.

A small amount of "Blur Offset" in the material texture may help as well by blurring high contrast areas in your high resolution texture.

I assume this is animation we are talking about -yes?

I was struggling with this a while back. Apparently this is something that was specifically adressed with v. 11. I upgraded and increased all the render settings that relate to this. It got a lot better but not perfect. One setting that might help is to set the antialiasing to PAL/NTSC.

Also there is a very good article on the Advanced render options in the august issue of 3D attack.

Sorry I can't be more specific.

*phew* work finally done !!

it's been a great project !

nope, it's been a still, not an animation. (no animation flickering ..)



but i changed the sampling options and the AA to best quality which all eliminated pretty much most of the effect.
