      Hy, I have this problem again and I have no idea how to improve the quality of the rendering. The surfaces, no mather how much i try to set up the texture, i don't get the result that i expect. (on some surfaces i followed instructions from tutorials, some of them from sketchucation users but with this result) On that blue light, someone said that i should use 2sidedface matterial, but i have no idea ho to make that glow, and the light fall on the floor.

      For that light i followed these instructions

        some more info if you can:

        • which version of vray for SU?
        • what are your rendering options settings (looks like they are rather low quality)
        • do you have a light source (omni light) inside the lamp? (you''ll need a light source under the lampshade

        The two sided material is created from the vray materials dialogue. You select make new material and pick the "2 sided material" option. Then you can select the base materials for the front and back when you edit the new material you made. The grayscale color sets the amount of translucency. Then apply the material to the shade.

          I'm using sketchup pro 8, and vray 1.48.93

          My rendering settings are default, i unchecked just GI color and BG color.
          I have a lightsource under that lampshade, omnilight, i know that the 2sided material must to be setup from vray material editor and i did that, both faces have the same texture.

          How can i raise the quality of the rendering ?

          Thank you

            Before anything else, update to the latest version. Currently 1.49.01.
            Whenever you encounter a software problem it's advisable to check for updates.

              In order for a lamshade like this to work, you need have a couple of things setup.

              1. your shade material setup in SU - no most shades in the real world have a different material on each side, so you want an inside and outside shade material.
              2. Make a 2-sided (not a Skp 2 sided) Material and call it SHADE or whatever you want.
              3. Make sure you setup that front shade and back shade material in that material setup for SHADE, and set the Color to a mid gray material - this controls how much of the back material you will see from the front. Place this SHADE material on to the lampshade model.
                NOTE: if you are like me and purge your file often, beware that purging will delete you front and back shade materials and then the SHADE material will no longer work.
              4. Make sure you omni light is casting a bright enough light. You may have to play with the values on this. I usually have my omnis set to Square Inverse Decay, Units to Radiant Power, give it a warm color, and set the intenisity to something like 40-50.

              When you render the scene, the light should be coming from the top and bottom of the shade and you should see the light hitting on the inside surface through the shade. If you want a softer shadow you need to adjust you shadow radius in your omni light setting.

                A trick I use for that is to color a line along the edge with the material that is in the 2 sided material, that way it is still in the model so doesn't get deleted in a purge.
