  • VRay - material reflection

    Hi you all!
    I use Skecthup with Vray to render 3d. I would like to get a metal/glass aspect for a material.
    I used a texture, diffuse (with transparency) and reflection layer. For reflection I utilized 2.0 for TextFresnel options (IOR) and 1 for Glossiness.
    In preview mode the material used looks good, as I would want to see it.
    But the material seems to not have the same performance in rendering.
    I attach an example of render and material preview.

    The objects with this material are solid components, with a thin depth (2 cm).

      The problem I see is that the glass in your rendered image does not have anything to reflect. You need to add an object or lights off camera so the glass can reflect those objects. Or you can even add a sky to your scene, that should reflect too.

        Thank you very much Reynold! I added my SunLight in GI. Isn't it enough? What can I do more?

          Think about a mirror and how it interacts with the world. If it placed in an area that is has nothing except for a solid blue sky and a light (sun) it will only reflect what it is there meaning you will only see blue and a light depending on the positions of each object. If you place this mirror in an area that has buildings, a sky with clouds, etc then the mirror will reflect those objects. The mirror in your case is the windows and in order to get more details in your reflections you need to add more detail in the environment. This can be as simple as adding a sky with clouds or as detailed as creating more buildings or objects.

            REYNOLDScreativ thank you very much. I thought that reflection works without environment too, but I will add one.

              There are a lot of opportunities for refinement there, so it's best to start with a general corrective statement: Everything is too large. More specifically, there is no focal point; no hierarchy; no...
