This is a basic tutorial on how to lower opacity on overlapping objects, without the overlap showing.This strip is a reply to Sketch 3 ..., Opacity 2 - Tutorial, Hellooooo
This one is for Neinire, but the rest of you are welcome as well! :-D
Choose the objects you want to work with
Arrange them the way you want
Make opacity 100% and THEN group them
NOW you lower the opacity to the level you need
Finish your drawing
The point is, that you group your objects BEFORE you lower the opacity.
Otherwise you will get the 'overlap'.
