[Radiance-general] Rendering parameters help and weird colors

[Greg Ward]

It does look like there's quite a bit of color bleeding, and the thin stripe of sunlight on the floor makes for difficult sampling as well.  You would be much better off treating your window as an illum in this case using mkillum.  You can follow the tutorial example at the end of chapter 1 if you're not sure how to do this:

> 1.- My environment is basically grey, but only the mountain near my building is brown; but everything has turned to be brown (as can be seen in Image2)... is that the "color bleeding" (or something like that)? Is that a good result? or there is a problem with my modeling?
> 
> 2.- As can be seen in Image (the one that shows the interior of the building, looking out), there are some weird effects, making my image to look as it was painted with a brush or something. What is the parameter that would help me reduce that?

> I am not sure why in Dropbox the images look much more darker than in my PC. They were created using rpict, and then filtered with "pfilt -x /2 -y /2 image.hdr > image.tiff"
