Outline radius too sharpen, a way for blur ?

[jonlepage]

hi, Is there a way to get more smoother radius?
Like a kind of blur filter ?
I find the outline of the radius a little too sharpen.

i also try to add a blur filter but not work, the light disappear.
Can be add a property called lens for soften the outline of the ray?
Is there currently a way to do it?
thank

That shader has function depends on radius in it. I'm sure you can modify it that way it'll be blurred

I confess you I have spend a lot of time trying different combinations, but I'm not able to get the desired FX.
I am maybe too demanding on the result, because these frankly not necessary fx.
But to better express what blur edge i try to get, I made a little photoshop here.

left it photoshopped blur, my target i want to get with light,
right original from pixi-light

It may not be possible at the moment, but I think it will give the result with a blur filter.
Do you know if the filters can work on a light element?
My try did not work, but if they supposed to work, I'll investigate deeper.

I just have to study now how the shader works in pixi and how implemented new .frag
there is a tutorial?
