ISL-question: color shader depending on normal angle to cam?

Post by zeitmeister » Wed Nov 23, 2016 10:31 pm

Hey there,
is there a way to access the polygon normal angle to the camera?
My aim is a material which blends steep-angled polygons invisible to the camera.
Thank you in advance!
Cheers, David

I think you can set something like this up in Xpresso.
Combine the Indigo Cam tag and Indigo Comp tag with a Boole and a rangemapper.
Plus some custom inputs on cam.

Or set up something similar via Python in c4d.
Kinda the 2 most viable options i think.

Doesn't this one use "camera normals"?

Hehe, tried this one but without success...
But it's possible; I think about the invidible to camera option.
Only as a ramp...

Good hint! Gonna try something... thanks!
But I would prefer a clean ISL solution of course. :-)

if you snap the code into your own shader, you need to create two color parameters named C1 & C2 respectively.
