Rendering only facing normals

#1

I have a model of human with an Xray shader, and I don’t want to render the faces in the back, just the front.

How do you render only the normals facing you up to a 90 degree angle? I don’t want to render the model from the background.

You want to do something like this:

if N.E < 0:
return(0)

And plug the result into transperency

N= surface normal
E= Eye (camera)

Pretty sure you can get all that from the sampler info node

Wow. Now if only I knew what you meant. I know a little about the sampler info (holds all the info the camera sees about the scene for each pixel?)

#4

You didn’t expect me to do all the hard work did you :wink:

#5

Nooooo…just steal your brain for awhile…that’s all. :stuck_out_tongue:

#6

Easy option: Just render your surfaces as single sided.

I’m using Maya. I’ve looked for something like that on the shader. Help files are not to clear. Where is that attribute found? On the shader, camera, display? Thanks for your help. :slight_smile:

On the shape node, think it’s called double sided, under render attributes (dont have maya at work)
