On the left side of the dialog we've selected Bitmap as the "Type" of map.This indicates that you want to define a bump "map" In the "Maps" portion of the material definition, click the check-box next to "Bump".You also need to add a "Bump Map" to your material.Use the resulting color-picker to to pick the desired color (gray in this case).Click the colored rectangle next to the word "Color".You can set the color in the "Diffuse" area.You can expand the material properties tabs by clicking on the names of the data categories ("Diffuse", etc.).You should probably right-click the name of the material to select "Rename" from the pop-up and give it a new name.In the Material Workspace (lower-left corner), left click on the material you wish to edit.Details of the selected material appear on the right (divided into categories), and in the Material Workspace (if expanded by clicking on the ""). On the left, we see a list of all materials defined in the project, one of which is selected. This is the way a new, undefined material appears in the V-Ray material editor. From the bottom of the dialog, pick "Create".Set the material type to "Plug-in" in order to define a V-Ray material.Activate the "Material" panel with the pop-up at the top of the dialog.Examine or call up the Object Properties dialog.Make sure V-Ray is the current renderer (as above).In the dialog box, use the Right Mouse Button (RMB) to click on "Default_VRay_Material".From the V-Ray pull-down menu, pick Material Editor.From the fly-out menu, pick V-Ray for Rhino.From the Render pull-down menu, pick Current Renderer.From the application menus, pick Render.Make sure V-Ray is the current renderer.Two Ways to Make a New V-Ray Material Starting from the menus
Vray textures how to#
On the rest of this page we'll see how to do that. For example, to make the rough concrete shown here, we use a uniform color (gray), and a "bump map" texture provided by a gray-scale image (below). Not all materials customize all of these. The data attribute we want to change is called "Material" or "Texture" in most programs.Įach material has a variety of contributing characteristics, including color, transparency, and bumpiness. Turning the simple gray prism into the bumpy concrete block is done by changing the way the surface is rendered, not by changing the geometry. Geometry in the real world is often multi-hued and bumpy, like the image on the right. Geometry made in the modeler is pure, smooth, monochrome, as shown at left.
