Hi every body ,

 

my scene is a walkthrough animation inside an office . i have noise on the walls near to the window , which is the only part that receives lights and shodows passed from the window curtain , i dont know the name of this kind of curtains but you know the ones that have closed and paralleld iron parts .

any explains ?

sorry for my weak english .

 

my setting :

vray sun and sky , sun shadows sub = 12

Adaptive qmc 1-8

irradiance for primary bounces _high animation

LC for secondary _saved walkthrough file with 3000 sub and .01 size , i tried to increase it to 0,5 and didnt work .

noise thr .002

it looks not like noise but incorrect texture mapping. noise is the small black grain effect.

 

the noise or grain on the vase is probably due to not enough blurry samples. Also, if you're generally concerned about noise, up the shadow sub.

thank you Stephen ,

i wonder if the reason is the mapping why just this parts have that tremplling , all the wooden wall have just one box uvwmap , i tried to raise up the vray sun shadow sub to 12 but it didnt work , i forget to say there is two vray lights on the left with default shadow sub .

Have you tried compose a ir map? Position camera, create ir map on disc, move camera do problematic area, create new ir map on disc, etc. Merging them all at the end with the irmap viewer tool. Use this as a irmap for the animation?

 

You could probably look up a tutorial on it somewhere on google? I dont have the working computer so I dont have the settings and names now.

Sorry to bring this from dead but i still have the problem ,,

 

here is a file showing the turbulence in the ir map ,even it have high setting http://www.zshare.net/video/113004948f896acb/

 

please i need help in solving this

 

just my 2 cents which has nothing to do with your animation because i havent seen it. you really should try to find a better way to host your animations. i tried to open in firefox but it won't work with firefox. i tried to open in IE and was bombarded with popups. besides that, there are 2 god-awful annoying flash ads and the video didn't load after 20 sec. i tried to close the popups and IE but that took almost 2 mins and required a ctrl+alt+delete. I was just about to do a cold reboot when it finally closed. I will never visit that hosting site again.

 

seriously, with the kind of quality you have shown in that first image, you really should be showing it in a more professional way imho.

What you're showing is not the irradiance map. It is the light samples. In order to look at the irradiance map you need to use the viewer. But, since you haven't saved an irradiance map, you wouldn't be able to show us that. You will most certainly get noise, flickers, pops, etc. when rendering an animation using the single frame setting.

I will not argue too much with you since you did not answer my last post until someone else asked you to do so.

 

i found the most recomend not to use saved IR in animated objects scenes, becouse its hard to get good quality with saved IR method in such cases!

 

I cant see that you are animating any object in your scene. You are moving the camera which is a different thing.

 

This is one of my favorite regarding VRay: [Due to spam control I cant paste the link. It is spot3D com -> plugins -> renderer -> GI -> Irradiance map.]

 

Towards the end of the page there is a headline reading "Mode", I suggest you read at least that part. And maybe you could try one of the other modes that are avaiable regarding IRmap. Both Spooner04 and me is suggest things you could try to do to get rid of your problems. At least consider try them, or argue with something useful rather than "dont think they will work, so I dont bother try"

 

Creating the youtube link finally let me watch (without the horror of "free-file-hosting") the video showing of your problem :)
