      SU 8 MR4 & 1.49.01

      Hi all,

      I've got a perforated metal material, and somehow I need to break it up into defined size panels. I could make a texture of the panel size, complete with panel edges and gaps, and tile that, but since the panel size could change (a lot), it occurred to me that it may be possible to define the panel somehow using texgrid. I played around with it a little and couldn't get anywhere. Anybody do this?

      Best,
      C

        Not sure Textgrid is the best way to do this due to UVW limitations in SU, especially if there will be numerous revision rounds. I would just make a JPEG texture of the panel in Photoshop along with a bump and reflection map (if needed). Use the Photoshop file to make edits to the panel(s) and reload.

          I've done something similar for Insulated Metal Panels. But I just made a tileable square pattern in Photoshop and then either resized it in sketchup or change the repeat values in Vray. Worked pretty well, but takes a little tweaking.

            Although i havent used text grid much i did get it to work.

            I placed a bitmap into the Fill colour, and a Texacolour into the line colour. see atathced.

            the size of the grid can be changed using the UV repeat channels. a couple of tests attahced, the first set at repeat 1, the second set at repeat 0.5.

              just noticed as well that the texture size can be adjusted using the sketchup native material editor, however this will distort the base image and your grid lines wont be a uniform width, so probably not ideal!

                bump.
                use the same tex grid sizes for repeat and line width, and set fill colour / line colour to black and white.

                test05.jpg

                transparency.
                in the diffuse - transpancy section use texgrid again. same settings as used elsewhere.

                now that i've learned a little bit more about texgrid, i can see this being really quite useful!

                  Very Nice! I like it with the bump, very nice effect.

                    ah, getting close.

                    is there a definable relationship of U,V values to sketchup units? or is it in relationship to original material texture size? I've never been certain.

                    say I wanted the panels to be in a 2'x4' grid (centerlines). Is this possible with reasonable accuracy, or is this what valero was originally getting at?

                      This test below is a box 5mx2mx1m (sorry, I'm metric). Base wood texture image set at 1mx1m

                      it looks as though its all dependent on the scale of the base image used in the texgrid fill colour. If the base image is say 1mx1m (as defined in the sketchup material editor)then that is the size of one panel.

                      test07.jpg

                      in this one I have adjusted the TexGrid repeat to 0.5, so each grid is 500mmx500mm

                      test08.jpg

                      and in this one I set the base image size in the sketchup material editor to 2mx2m (UV repeat back to 1.0)
