How to make sqare/sharp lines with Grease pencil? Every line ends up in either a fade or a circle.
You can sort of achieve it by scaling down the last point in the stroke, but you have to do it manually every time! and it only gets you a triangle instead ;-;
Basically, I want to make a line as normal, but the corners and ends must be sharp ... and I cannot for the life of me figure how to do that.
With vector art is very simple ... but Blender can't do that.
If I understand the question, you want tapered straight lines?
When I tried this with default settings I got faded ends. But I found that this can be fixed if you:

Turn Off Strength Pressure (which should be all you need to do)
Adjust the Thickness Profile to move the outer Left &amp; Right control points slightly up from the bottom of the graph (which is least thickness)
