the softedge shader seems to add a bright stripe at the end. its not very obvious and usually only visible on bright grey background. i’ve seen it before when doing a multiscreen installation but i thought its due to bad projector gamma.
is this an optical illusion or actually a wrong alpha ramp ?
it always there, no matter if i change the code and/or the gamma value. what i forgot to mention before, this shader is an essential part of the multiscreen nodes. people might run into problems using them with softedge. not a problem with black or very colorful background.
one easy solution is doing the softedge with a dynamic texture + quad.
