Faded mesh edge shader

PostPosted: Thu Mar 28, 2019 9:33 pm

I'm working in AR and as such, I want to create little patches of dirt on a plane that can blend with the users "real world". I simply want to have a plane shaped mesh as shown in the screenshots and have the edges be faded or feathered to transparency.

What I Want

How can I achieve this? A Fresnel affect almost does what I want, but its tied to view perspective, which does not accomplish what I'm looking for.

Thanks in advance.

Hi

for the moment i think of two things:

- use a simple planar projected (from top) mask texture

- play around with the depth fade node
