I'msorry I could not come back earlier. I had 39 C (102.2F) in my office yesterday and my computer slowed down, it was boiling. Will be the same today. I need to shut it down to cool it.

You're very welcome Philywebrider and we will try to answer all your questions.
I don't know MightyJoe (MightyPete maybe??) And I don't understand the description either. If it is MightyPete, he is very good in Vue and computer techniques and can answer lots of questions, but his slang text is for me, as a non native English speaker, completely confusing too.

So if you wanted to speak about "unclean" renders, you need to select RENDER OPTIONS from the menue PICTURE. Then select USER SETTINGS and click, under ANTIALIASING the EDIT button. There you can put all the sliders to its maximum before you render your image.

This reder will give the best result. Not fuzzy, not grainy.
Now, if you use bitmaps as textures in your image, they should be atleast the same resolution as the size of your final image.

Fog and haze gives some kind of fuzziness if you like it, but you also can turn off FOG and HAZE in the Atmosphere editor. Click F4 to open it. But you must know that Fog and Haze completely tourned off will darken especially volumetric atmospheres.

When he sais don't be hurry, tis means that you should be aware of a long, very long render time if your image contains water, reflective material or more then one light.

I think the answer you got from rds was not meaned as you understoud it. He just did not understand your request either.

Now, I'm not sure I have answered your question. That's why, if you could post a small render to show us we can see and help you much better. Everybody here is helpfull, so feel free to ask.
