Transparent reflective floor

[Vickiann Vachula]

Hello all,
I'm very new to vray just switching over from mental ray. I would say I am a lower end intermediate user.

I am an exhibit designer and in mental ray, I was able to create my exhibit on a clear floor using an autodesk glass material that would reflect the exhibit yet be entirely invisible. For example, if I had a colored gradient background, you would just see that background, the exhibit and the reflection - no trace of the "floor". I have been unsuccessful duplicating this effect in vray. I tried a standard glass as my floor, but it renders completely black. I've combed the internet and I can't find any solution. Is this possible to do? I'm attaching an example of what I'm talking about. Thanks in advance.

Get familiar with V-Ray materials (like glass...), lighting; etc. It is unavoidable. This good: http://www.3dtotal.com/index_tutoria...ed.php?id=1216
If you have a gradient viewport background, set it also in the Environment Map.

Thank you for the tutorial link. Any instruction is helpful. I was hoping that there would be a simple solution - rather than set up a whole studio environment (floor, backwall, ceiling, etc). With mental ray I would just create a cylinder as my floor and use a glass material on it. I don't understand why a vray glass material renders black on my "floor". I am using the gradient as my environment map, not a viewport background. Actually, in this particular case, I'm trying to use a plain white background (no gradient) and have my reflection. For some reason, white is rendering gray. Vray is extremely frustrating so far

Post an image with your result. Anything else as lighting, material descriptions could help with you getting an answer.

Refl Test.jpgI placed a plane underneath the objects.
Made a vray material with some reflectance and pure white refraction with 0.0 IOR and assigned it to the plane.
For the background just drop a pure white color in under environment or a gradient.

Hope this helps

Thank you Yohkoh! The IOR setting was the problem. I have so much to learn. Thanks again

Also thanks to Ismael. I so appreciate the advice. I'm off to go watch some tutorials...

Also, if you set your reflect/refract override material in the vray environment tab to the same map as your background your ground plane will always reflect it in the absence of anything else to reflect. The result is a blended gradient that extends from the background onto the ground plane and into the foreground. You only need to have a reflective material applied to your ground plane. No refraction required...
