<![CDATA[[ANSWERED] ​blur edges for projection mapping]]>Hi all 

Does anyone know the best way to blur edges when projection mapping with Izzy? the lines are quite jagged around the edges of the projection surface 

Many thanks

I regularly check to see if the blur handling in mapping has been improved. And the years go by, and I'm surprised every time that it hasn't been implemented. It's sad; I love this software.

Curves don't really exist in a digital world - only blocks of pixels. And if there are not enough pixels you get "steps".

Here's the forum link: https://community.troikatronix.com/topic/6617/solved-new-shader-fade-out-soften-edges-of-projector-output?_=1737559689583

For more complex masks here are two options provided by @DusX and @Ubik from the forum: https://community.troikatronix.com/topic/8138/answered-shapes-mask-assets-feathering-in-izzy?_=1719215668331 / https://community.troikatronix.com/topic/8871/user-actor-virtual-stage-feather?_=1737559964139

Hope these help

I would find that very handy.

Cheers,

Hugh

(any imported media, video image processing in Preferences - Video, and Output in IzzyMap.)
