what are you NEW???

[namleklag]

YES, and clueless!
all I want is for the texture that I'm applying to always remain the same dimension
no matter what size plane it is being applied to...

i have a grid pattern I'm trying to apply both to a wall and and a roof.
the roof grid renders many times larger than the wall.
i would like to decide that the grid is always 12"x12" for example

any help would be appreciated
please explain like I'm a fourth grader
-thank you

Re: what are you NEW???

Welcome

What you're trying to do is not something done through V-Ray, but through Rhino. Once you've applied your material (with texture) to an object you will need to use Texture Mapping to define how the image appears (in terms of size/orientation) on the object itself. With the object selected and the material applied, you will need to access the Texture Mapping part of the Object Properties (type Properties in the command line if you don't have it open).

Now you will need to check the box that says Show Advanced UI. This will make a few things appear...a whitespace that has the column headings Channel and Mapping, and some buttons below. Click Add (the first button below) and you will see a 1 appear in the whitespace above and a bunch of new parameters down below. In the General section you will see that the Projection is set to Surface. This is the default projection type, but you can change that to a few others. In this case we'll change it to Planar.

Now that we have a Planar projection assigned to the object, we can set its size. The third section, Size, will allow you to type in the desired length (x) and width (y) values that you would like (don't worry about z for planar). So if you want it to be 12" x 12", then you should type that there. The numbers in that dialog box are in scene units, so if you are in inches you'd type 12x12 and feet you'd type 1x1.

Lastly, if you're doing a roof (or lets say a wall), you may need to reorient your planar mapping as well. The easiest way to do this is to turn on the Mapping Widget by pressing Show Mapping. This will have the mapping widget be a selectable/transformable object within the viewport. You can now select the object and rotate/move it around so that you can make that mapping match the object you're working with (if you haven't modified the size, the mapping widget might be right on the edge of the surface, so you might not see it. Try and select the edge of the surface and rhino should ask you what you want to select). When you're done moving the widget around its a good idea to click Hide Mapping so that you don't accidentally move it around
