Thanks a lot for your answers :-)
Yes, i´ve seen already the Cloud section, but i´m not satisfied with the result, as you can see in the following picture:

Second Picture: Old Cloud Modell Frank´s thunderhat: Flat, complete whiteout and looks not satisfied at all
Here you have more options but the result is poor
