  • UVW mapping materials

    Hello everyone!

    concerning UVW mapping of materials in Vray for Sketchup, I have two questions:

    - while customizing materials, I came across the option to choose a UV channel/set in the 'texture placement' menu. By default, this is set to 1 but you can change to any number up to 99.
    My question is, where can you define these different channels?
    It would be extremely handy to have different channels with different sizes or properties, for example in order to avoid tiling on large surfaces etc...

    - I read that in vray for 3ds max there is the possibility to somehow randomize your UVW mapping, so that copies of the same object (eg wooden planks of a book shelve...) do not look exactly the same. Is there a similar option in Sketchup?
    Right now, my solution is to manually manipulate the texture of every object by moving and rotating it, but as you can image this quite time consuming when it comes to making 50 fence poles look good...

    Hopefully, somebody can shed some light on this!
    A very grateful thank you!

      Hi kenancakir, thank you for the video! Although it was in Polish, I could follow most of it
      This method can indeed be a help to overcome the second issue.

      Anybody any thoughts on the first one?

      greetings!

        This is limited by SketchUp's functionality. The maximum you can set is one map channel for front face and another for back face.
        Keep in mind .vrmesh files may contain more mapping channels, so if you create a .vrmesh or .abc file in another platform you can utilize all of its mapping channels in V-Ray for SketchUp.

        Kind regards,
