Thanks Len... will take a look at this later on... I figured out the noise reduction part of it myself actually after posting thsi and also the switches... 4am... that's my excuse... It became obvious after about the temt mode etc being no more than switches... What I did n't know about was the info,,,

The raytrace part of the settings I am familiar with from 3d but the Stepwidth stuff I was not familiar with but fiddled around with it and got an idea what it does.... That said any time I tweaked the fractal view I had to go back in and fiddlwe with the stwpwith stuff ...

Only with this fractal so far... 

think I've already got the 'steer clear' message... Just wanted to see whay could be done... not sure why formulae like this get included when as you say they tend to be inherently noisy or complex... Rather not have em in... Same with 'redundant' formulae I find in several other frac apps I use...

Thanks again my friend
