Xray shader - Backface cull?

[Deflaminis]

I have an xray shader that's working out for me. The only problem I have is that it's showing parts of the I'd rather it didn't, specifically the backside of the model and the soulsucking looking mouth. I need to somehow clip out the back areas, and so far I've fallen short. I'm using VrayLightMtl, but I also tried a regular VRayMtl (though I prefer the 'multiply by opacity' on vray light mtl) but no luck. I think I've been up too long and I'm drawing a blank.

Tried to get fancy with some towards/away masking but it's not really panning out. Any tips?

Thanks,
AJ

cant you just use the same falloff to mask between a flat black material and your lightmtl (without transparency)?

if you need it to be transparent over a background, comp it.

See... that's what I thought. Maybe I just made a mistake, will take another stab at it. It'll be animated so I need a procedural method, but I just really hoped to find a way to ignore anything past the 1st set of faces.

Sorry to dig up an old post.. Did you ever find a way? I'm also wanting to create the same effect.

not sure if i remember correctly or if it will fit for your shader
but i had the same issue once,
you can try to turn off "visible in refractions" in the vray object properties, hopefully helps

I'm away right now but this weekend I'll dig up my files and see what I did. I think I made a copy of the object and pushed it in a little and made it matte black.
