Matrix Setup
WLED has a handy 2d-matrix setup feature that will take care of the mapping for you on a rectangular matrix. Our matrix is not quite rectangular, but we can pretend it is by "unwrapping" it with our minds. Let's pretend we cut the LEDs in a straight line up the back of the hat, and then laid all the strip flat on the table. (Don't do this for real!) Now we have a rectangle we can use as a matrix.
Go back to Config and choose the 2D Configuration tab.
Change the dropdown to read 2d Matrix, and additional options will appear. If you want to sync more than one panel, you can do it here.
Set up your layout numbers to match the number of rows and columns in your project. You can also change orientation here - my pixels start in the lower left corner and finish in the upper right.
Count the number of pixels around the hat in one revolution to get your horizontal number, and then count the number of strips stacked up to get your vertical number.
If the effects don't look right, try adjusting these numbers until your animations "snap" into view. When the mapping is correct, it's like your project suddenly comes into focus.
Matrix Effects
WLED has a hefty number of matrix effects that appear in the list when you've got your 2d matrix set up. Click the little square in the "filters" popup to see only the 2d matrix effects. Many of them can be customized with speed and intensity sliders, or different color palettes. Go wild!
