You could make a png alpha mask with photoshop or something and make a gradient with that to simulate the shader..you would just blend it on top...maybe make a mockup of what kind of image you're going for? i assume you want to use facetracking and just blur the edges a bit or something? or have a round selection?
Hey, thank you !
You are right about a png alpha mask…
My goal would be to blur just face edges, not just round selection…
Wouldn't it be possible to create a mesh thanks to face edges to make the alpha mask ?
I'm pretty lost right now :)
