I usually see that when I render with one of the other rendering engines besides the default "Packet Mode", especially when using the "Path Tracer". Could that be the case for your?

Those other engine will eventually resolve, and the dots will disappear, but it takes more passes

The Rendering Engine choice is location on the Options/Render tab.

Okay, I liked the looks of the path tracer better so thats why i picked it, I'll try with more passes.

Also, do you know how to fix that wierd shadow on the bed?

I cannot tell what you are referring to from that picture.

The shadow that is ontop of the bed, is "weird" if you see what i mean.

I can't tell from just looking at it.

Can you post the model here, by uploading it as a zip file?

Apparently the file was to big so i uploaded it to Mediafire: http://www.mediafire.com/download/m180tr4g4oyz8mv/Room+to+scale.rar

Also, This is the reason i want to use path tracer(it looks more realistic) http://gyazo.com/573474b2dd01d174f3f31d60852eb035

The problem with the "shadow" on the bed is not a shadow at all, but is an artifact caused by the normals that we get for the faces in that surface. THey are not handled well by any of the rendering engines. This surface for the bed has 90 degree corners that are set to render as soft corners. It looks good in SketchUp, but does not render well for us.

I thought that perhaps this was something new that had been introduced, so I tried to render a simple box with softened cornder in an old version of IRender from a few years ago and got the same result.
