unclefestor: First i need teach how work with color picker,.. i will find your tutorial... and maybe i try it.
Once you get the hang of it it'll be easier to find Structures Via hex. You'll start to see patterns in the strings that let you know if it's a color, float, or boolean property.
You'll need to get an understanding of how each one functions to make use of the values. For the most part you never want to change a bool prop. You'll want to focus on Floats and Colors. With color Picker 3.6 it should place any Floats it finds in the Alpha box. You can change the Values Directly through that box using the numbers instead of the Color Wheel. I believe UDK uses a Structure Float Range of 3 to -3 so you'll need to stay within that range.
When adjusting Floats of a Scalar Parameter I would adjust it by the 1/100th decimal point Example :
Float : 1.26733241 {Start by increasing or decreasing the # 6 (100th decimal point) and work backwards towards whole integer (1/10 Dec, 1 Whole #, then back to 1/100th Dec)
