Vray reflection render issue

brknbrkn · 26 Jul 2012, 17:22

Hello all,

I'm trying to add a reflection to my material using 'Add > reflection layer"

However when I make a render using default settings it just show my material in gray-scale. No matter what I change in the settings, the output is always in a gray-scale. What could be the reason for this?

Using SU 8 with vray 1.48.93

Thanks.

you have either Override Material ON in Global settings, or in VFB you accidentally turned off one of the colour channels.

Do you have an environment around your object? Make sure there's something to reflect. Can you post an example of your render?

Thanks for ther replies. Running Vfs 1.48.93

I allready made sure override material was unchecked and in the VFB everything is set to default. Allthough whenever i want to save the render to a .jpg it automatically makes an Alpha image of it :S

Also I understand you need something around the object to get a reflection but the problem is that it isnt even showing the orange color I assigned to it, but just a grayscale.

It looks like you are seeing the reflection of the sky. Try giving something to reflect to your reflection layer.

good luck

@oganocali and the rest.

I am quite new to rendering scenes, so how and what could I add in the scene to get the result.
I understand by adding a object to the scene I will give something to the material to reflect to but what I dont understand is that as soon as I add a reflection layer to a material the complete object will be in grayscale..

Maybe it is usefull to add my scene, download here: http://www.efpp.nl/flatdown.rar

Try clicking the "m" button (Mapping) next to the Reflection color and adding a fresnel effect. You are making the face a perfect mirror, and as such, you are getting the whole plane reflecting the color of the sky/background, and NOT a reflection on top of your diffuse color.
