      Oh yeah also this; the placement is dependent on the origin of the model or component. I'm not exactly sure how the difference between applying a material to a face or to a component is in play, but the component axes thing is clearly demonstrated in the example below:

      wood_thingies2.jpg

      In this image, the two little blocks on the floor are the same component - one of them made unique and the axes of that one have been put at an angle of 45 degrees in two directions.
      As for the balls, they are the same component, one of them is rotated.

        just for reference, how big are your... items? ('balls' would seem inappropriate ^^)

        my sphere is 2,646m in diameter.

            may I publish here a little tutorial on how to use the Vray Blend Material?

            It's useful to have bump maps without a diffuse texture (sort of)

                Yes. But please post in a new thread, and tag it [Tutorial] so it's easier to find.

                      hello winGman,

                      create a material, open it in material editor:
                      [attachment=1:bo417hjm]<!-- ia1 -->texgrid_tut_1.png<!-- ia1 -->[/attachment:bo417hjm]
                      assign the TexGrid texture to the Diffuse channel (or some other channel, depending on your desired usage) and try to play around with the UV repeat values to adjust its size:
                      [attachment=2:bo417hjm]<!-- ia2 -->texgrid_tut_2.png<!-- ia2 -->[/attachment:bo417hjm]

                      after this, my render looks like this:
                      [attachment=0:bo417hjm]<!-- ia0 -->texgrid_tut.png<!-- ia0 -->[/attachment:bo417hjm]

                      and that should be it 😄

                      is there anyway we can change multiplier by measuring tilesize. ? this would be useful while making bump maps for tiles divided in a grid. say if i want tilesize 300mm by 300mm how can i do it?

                        my 50 cents to help your quest. 💭
                        recently i discovered that for the textures rock - stucco - smoke - snow - speckle - splat - water you should untick "use 3d mapping" to enable UV tiling control. 👍

                          Has anyone ever come across any clear documentation for all of these effects? The fact that there are so many cool procedural maps available, but the tutorials for how to utilise them are not seems a waste.

                          I've spent a good few hours playing around with them before but managed to get no practical use out of them because, as you know, with all the variables you can change it would take weeks or months to learn anything through trial an error.

                          This is probably less of an issue for Max users who tend to have had some kind of professional training, but those who use Sketchup for visualisation are at the shallow end of the visualisation pool are largely self trained I imagine. (Along with using amazing resources such as Sketchucation, of course 😉)

                              Do the original images to this thread still exist? I've been looking for this information on vray materials for a while, and this is the most promising result.. but it seems the image links are no longer valid? Or, can the information be found elsewhere?

                                hm, it seems my access to the old server got taken down (or my files have).

                                i'll try to find the images somewhere in my backups... however, all of these were for vray 1.49 and the question is how relevant they still are.

                                but as i said, i'll try to find them, just in case the were.

                                    Hi, I haven't found the images.

                                    But after the school's done in January I'll try and recreate the post again; the question is, how many people would be interested in the old 1.49 version and how many in the new VRay 2.0, since I imagine quite a lot of people have adopted the new release.

                                    let me know,

                                        Hi, I bet many have asked or noticed this already- the "reset color" in material editor is greyed out since I installed Vray, now it's hard to revert to original texture after playing around with sliders. Also, my textures was automatically saved and renamed into a temp folder (Chaos Group), not a big deal though..

                                        Have someone figured out how to unlink Vray from overriding my materials control? I appreciate any help, I'm really hoping to get the "reset color" button working again. Thanks a lot!

                                        PS: (to Admin) If this is the wrong section, please move it. thanks!

                                          This is something you should report to the V-ray for SketchUp developers so they can address it.
                                          (Also, it's useful to include V-Ray and SketchUp version when asking questions like this given how different version may act differently.)
