Lightbeam fade

zombie420

Using the UDN Lightbeam tutorial, I made some light beams but they don't really fade like I'd like them to; the edges are too crisp. How do I fix this?

use a fresnel in the alpha, or make a cheap one by taking the dot product of a Camera Vector and a constant 3 vector of 0, 0, 1

or if it;s all emssive and not using the opacity slot multiply everything by that setup.


edit: you might need to run the dot product through a abs also.

if you dont quite under stand i could post a material network

I'd honestly say bevel the edges a bit and then remerge the top corners, it should look pretty good.

Hey man, really appreciate the offer. I'd love if you could show me your material network, I've never used a fresnel or abs node
