filter area acting strange?

[colourclash]

I was trying out some filter effects in Pixi 4 and noticed by setting the filterArea the region outside the area is no longer rendered. i.e. black
Is this the intended behaviour a filterArea? I was hoping for the filter to be applied only to the specified area and leave the rest of the image unaffected.
I made a codepen here http://codepen.io/anon/pen/VjAGmJ

That's how it always worked. We are working on new stuff called "blendFilter" that will doexactly what you want  If you want it right now, you can hack https://github.com/pixijs/pixi-picture that way instead of adding OVERLAY/HARDLIGHT blendmodes it applies your filter.

Okay, thanks Ivan, good to know!

So if I need the filter to be applied only to the specified area and leave the rest of the image unaffected (for example, blur for the half of image), I should use pixi-picture plugin with blendModes, should I?

If you put your shader instead of overlay, yeah. The other idea is to track "Backdrop" PR for pixi , take that branch and make your own blur based on it. In any case, its all for advanced users who dont fear of the core. Unfortunately, my PR's that make it easier for users were rejected.
