Visible to reflection/refraction issues
show user profile  preciousSTONE
Hey guys,

I have an issue that keeps presenting itself. Oftentimes I have an object that I want to reflect but not refract or vice versa. In object properties I can untick 'visible to reflection/refraction' but I really only want to disable it's visibility to reflection.
Is there a way I can do this? Hopefully theres some fancy part of max that I've somehow missed. If not, perhaps a script?

I'm using max 9.

Thanks in advance for any help.

Cheers,
Lisa

i know you can do this in vray via the vray properties, but i've never seen the two seperated anywhere.

FinalRender also has the two options separated in its own tab in Object Properties.

Nothing for mental ray though, right?
I was hoping there was a hard max solution, not a render-dependent one.

It's so frustrating!
Thanks for your replies guys :)

Thanks Bolts. It's just something that's bothered me for a while.
I guess I'll have to render in passes.Makes it hard to test renders though.

Enough of my whining :P

> I have an object that I want to reflect but not refract

Isn't that called a mirror ?

If you want some kind of weird mirror that you can also see through, you could use texture alpha transparency as I think mental ray ignores it ... or at least it did when I ran a test a while ago.

You'll be able to see through due to the texture alpha, but the ray tracer will stop at the surface because it 'thinks' it's opaque. (it doesn't perform per texel opacity checks)

Advance, Lisa wants something that is visible in reflections, but not refractions.

*Hugs Vray*

Now that I think about it... what is your situation, that you need the object visible to refraction, but not reflections? I'm not questioning the need for it, I'm just curious :)
