STRAT Posted April 3, 2008 Share Posted April 3, 2008 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. Link to comment Share on other sites More sharing options...
ayman jaibat Posted April 3, 2008 Author Share Posted April 3, 2008 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 .

kbotnen Posted April 30, 2008 Share Posted April 30, 2008 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. -K- Link to comment Share on other sites More sharing options...

Brian Smith Posted April 30, 2008 Share Posted April 30, 2008 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.

ayman jaibat Posted April 30, 2008 Author Share Posted April 30, 2008 Sorry about that Brain, i hope this may clear what i mean ,, about the splotches in specially on thee wight wall . this rapidshare link for the animation :http://rapidshare.com/files/111521450/Movie_0002.wmv.html Link to comment Share on other sites More sharing options...
Brian Smith Posted April 30, 2008 Share Posted April 30, 2008 sorry...i dont ever touch rapidshare either. it tells me i have to wait 60 sec..and while that is a bit annoying, it's more about all the piracy that goes on with that site. i would suggest youtube in the future or something similar.

Spooner04 Posted May 3, 2008 Share Posted May 3, 2008 Someone asked this already, but I will ask it again since you didn't answer them and it is important. Did you render out and irradiance map and save it to your disk before you rendered? Link to comment Share on other sites More sharing options...
BrianKitts Posted May 3, 2008 Share Posted May 3, 2008 turn off "show samples" in your irradiance map..... Link to comment Share on other sites More sharing options...
ayman jaibat Posted May 3, 2008 Author Share Posted May 3, 2008 (edited) Hellow again .. Spooner04 ..... no i didnt , it's just frame by frame BrianKitts ...... its already turned of , ,,, i didnt render final images to show the turbulence in IR map.

Spooner04 Posted May 4, 2008 Share Posted May 4, 2008 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. Link to comment Share on other sites More sharing options...
ayman jaibat Posted May 4, 2008 Author Share Posted May 4, 2008 As my brevious search in this forum , 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! Link to comment Share on other sites More sharing options...
kbotnen Posted May 4, 2008 Share Posted May 4, 2008 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 -K- Link to comment Share on other sites More sharing options...
ayman jaibat Posted May 4, 2008 Author Share Posted May 4, 2008 kbotnen ... sorry about not answering breviously ... in my first tryes i used the method in vlado's "rendering with animated objects" tutorial but i had those splotches and pops .... i didnt compose any Ir's yet , i will try to find tutorial ... my movie have animated books . pages , it didnt appear all in the link ,,,, Link to comment Share on other sites More sharing options...
ayman jaibat Posted May 7, 2008 Author Share Posted May 7, 2008 the problem seems to be solved ,,, just by increasing clr tresh , Hsph and Interp Subs values , lowering min rate in IR map becouse the out put 720 * 576 Thank you guys Link to comment Share on other sites More sharing options...
