blurry render

[bswalter]

hey guys,

im new to indigo and skindigo. i have downloaded both, and have spent a good amount of time reading these posts...my comment/question is- im rendering an exterior of a building in sketchup. I let the thing render overnight (14 hours) and it still looks like there is a layer of 'sand' over it and the edges aren't crisp. Ive downloaded and looked through the tutorials put out a while back and am still at a lost. the camera setup is at a viewing range of 1750x3000. is there another program/plug-in i need to install? any help would be great. thank you.

sounds like it's noise and you need to render longer. which tracing parameter are you using?

I have an exterior that has been rendering for over 80 hours and there is still noise at the windows,:shock: it's a night shot with lots of lights.

Hey bswalter, welcome to the Forum!

please post your render, so we can see what you talking about!
Some Information about your CPU would be nice too

thanks for the welcome, im attaching a rendering (the 12 hr) one...it was a rough model i threw together to try out this program.

the tracing method(?) im using is 'BidirMLT' and my CPU is a lenovo intel core2, 6400@2.13 and 2G designated Ram with a nvidia graphics card (somewhere in the 7000 range if i remember correctly).

i appreciate the quick responses.

Hi bswalter! Nice to meet you!

Er, i don't know if it's a problem of mine, but i can't see any image..But, i try to answer you from what you've described above.

It could be a matter of noise, as crojack wrote you; or it could be a little Depth Of Field issue: try having a look at the camera parameters rollout. You see the first parameters is "aperture": a higher number means you've a smaller diaphragm and a consequent longer DOF. In practical terms, the bigger is the number, the further you'll be able to see sharp edges. In theory a higher number would need a little work about exposure times, which would be longer, but with the Reinhard tonemapping (which includes an auto-exposure option) it's all ok.

So, try setting the aperture rollout to f/22..
