Please can you explain better what the "Random Strength" values are for - the tutorial doesn't explain what they are for at all, just to set them to 0 and 70%.
I absolutely have NO idea what these two fields are for - there is NO explanation anywhere.....
Is it a 'from' to 'to' situation ? If so, 'from' meaning what, and 'to' meaning what ?
Then there is the gradient - what is that about ?
Please, please, please can you explain this because it is driving me nuts.
To me, it seems there are too many variables at play here to make any sense of this.....
