Magic Music Visuals

Hi,

I'm trying to figure out how to round corners of a polygon, i.e. add a border radius.
Tried masking a circle and a square, but the result looks ugly.
Do you know a simple way to do that besides something like writing a custom shader?

Thanks!

A bit of blur and a some contrast will give you these - they will interact in a metablob kinda way if they get too close, which is a nice effect too.
Adjust the fillet by changing the blur amount.

Honestly I would just do this in Photoshop and then bring it into Magic as an image.

There are many apps that can create shapes with rounded corners, but there are advantages to being able to do it directly in Magic.
