Welcome to SketchUp, Vray and other Resources

Everyone is capable of learning. Learning is part of life. It is a social process of living and bringing everyone to share their inherited resources and discoveries. All of us can influence the life of others through sharing and caring. It is our belief that everyone should be a lifelong learner.

I am putting very important visualization resources and series: tutorials, tips, tricks, VRAY materials and settings, and mini-the-making (MTM) processes.

Tutorial: How to simulate lampshade materials in Vray SketchUp

Vray double sided material allows seeing the light on the backside of the objects. Vray artists use this material to simulate thin translucent surfaces like paper, lampshades, curtains, leaves and others. Gerbe Dumahil explained in this nifty tutorial how to simulate lampshade material using double sided material in Vray SketchUp.

Other renders done with the same technique.


  1. Does the two sided material has to be painted on front and back side of the face? Nice tutorial I am having hard time making curtains and lamps. Thanks

  2. great tutorial i like your style :)

  3. This comment has been removed by the author.

  4. That's great! Thanks a lot!

  5. Not working for me. the 2 sided material is mixing front/back colors but any light comes through material. vray for sketchup 1.49 / sketchup 8 pro / system win 7 x64

  6. aql.. well increase your light inside.

    1. Almost a year later... :)
      After increasing light from 22 to 1100 still no effect.
      What fresnel parameters shoud be applied to reflection layer?

      in your 2SIDED8.jpg the LAMP material in sketchup scene is semitransparent. The material I got in sketchup after using the settings from the tutorial is completely opaque.

      When the LIGHT material is rendered, provides high gloss material such as plastic or latex but is completely opaque.

      can you say what version of sketchup / vray do you use?
      can you upload working material (of full scene w. materials) to forum?

      Thanks in advance

    2. same problem but finally found the solution.. i'll try to explain here, but sorry for my english.. you just have to make sure there are no beveled surface in the object, beveled means there are 2 planes between the light source and 'camera'.. if you create a box between light source and 'camera' then no effect happen.. if the light source inside the box, then it will happen.. i hope you understand what i meant..
      that works for me..

    3. hello, the solution is:
      1- select the faces
      2- go to Vray materials editor and apply 2sided-Material to selection.
      and enjoy.. it works for me.. thnx good Tut

  7. hello thankyou very much for your tutorial, i just give some suggestion: may be you can move the picture tutorial no.5 change to be no.4 and no.4 change to.5
    becouse if i follow your tutorial ,really i will confiused to find /lamp when I change the 2 side material, becouse we not create material /lamp yet,

  8. Fantastic tutorial. Really easy to follow and great results.

  9. cool!!!thank you sir for sharing this helpfull tutorial

  10. Excelente tutorial lo segui y me funcino perfecto. Gracias
