I presume the trees are actual geometry - and not just a background image.

Give it about 3 times as many passes and see if the dots go away.

3 passes? this took 10 hours haha and it took only 7 bars or so..so i stop it.. Did the trees made the rendering slow?

I meant, if you had rendered it for 20 passes, then try 20 X 3 (or 60 passes). Some problems go away with more passes. The lighting in this model is fairly complex, and it is going to take a lot of passes to resolve it.

Yes - the trees are probably slowing things down. Sometimes you just have to make the model simpler.

Did you use IRender nXt trees, or trees from some other source?

One trick you could use for this particular view would be to render the model with the trees in an invisible layer, and the ground turned off, save the rendering of the building as a transparent .PNG file, and then paste it on top of the original image, or paste it on top of an image with just the trees, but not the building.

The trees are from google warehouse..

If you get a chance try some of the IRender nXt trees and see if they render faster.

Nice lighting. The chuch glows like a lantern. Is the Indirect Lighting (under Lights) set to Gather? Gather looks cool, but takes a while to lose the dots. If so, perhaps switching to Standard (or None) will get rid of the dots.

The other thing I can think of is the ground and building textures might have a sandpaper procedural map used in the material setting. If so, the little sandpaper bumps could be reflecting some of the stained glass light - at least until a few more passes smoothes them out!
