So we have box mapping, cylindrical mapping and spherical mapping. Rhino’s texture mapping also has some mapping types that use geometric primitives. And of course I can scale this, and if I scale in 2D then my texture will increase or decrease keeping my checkerboard size square.
So for example, I can take the texture mapping widget and I can rotate it and my texture will update and I can move the widget and you’ll see the texture moving here. Okay so now if I want to look at the mapping from the texture mapping options here, I can choose to show the mapping and this mapping widget here can be used to control the mapping as it appears on this rectangular surface. It will take a little while for V-Ray RT to catch up. You’ll see now that my texture is now mapping correctly. And I’m going to type in the length for this and the height for this rectangle and then choose the UV option. So I go in to object properties and texture mapping, and I’m going to choose planer mapping and describe the rectangle that is used to map the texture. So to get back to a square checkerboard texture on my rectangular surface, I need to employ some texture mapping. You’ll see now my material updates and on the square surface here my texture is correct, but of course on the rectangular surface here, the texture is stretched over the entire surface distance. So go to the texture editor, apply a bitmap texture, add all the default settings.
I’ve got a test material in here and in the diffuse layer I’m going to add my texture. The texture I’m going to work with here is this checkerboard texture and I am now going to open up my V-Ray materials. Let’s now take a look at what happens when we need to move beyond simple UV or surface mapping. Again, we’ll see that the image previews and displays in both the Rhino rendered viewport and the V-Ray RT viewport and you’ll see as we navigate around the can, you’ll see that the texture applies itself correctly all the way around the image. So open up the V-Ray material and in the diffuse section here, click on the M symbol which is a little further along in this dialogue box here, again choose text bitmap and then navigate to our image.
To look at this, let’s now look at how we create a texture on a V-Ray material. However, of course, in this case where we have a cylindrical surface that has the correct length and height, then the image will map correctly around the tin. If we then for example adjust the surface, in this case just by moving the control points, you will see how the texture stretches and deforms with changes to the surface. If we have a correctly sized untrimmed surface, and the proportions of our texture are identical to this, then we’ll get a one to one match of the texture on to the surface. This uses the U and V parameters of the surface to control the size of the texture. We are not at present using any texture mapping, so the default way in which textures are applied to surfaces in Rhino is called surface or UV mapping. As soon as we do this, you’ll see that our image is applied to our surface. We can open up this image, we can check in the preview here that this is the correct image and we’ll leave everything else here at default and click OK. We can then navigate to our PNG image that we want to use.
When we click on the M symbol, and then choose text bitmap. Next to the colour slot in the diffuse layer, you’ll see there’s an M symbol. I’m going to expand the standard material and go to the diffuse layer. The texture that we’re going to work with is this PNG image created in Photoshop and we are going to incorporate this in to both of the standard material types for V-Ray for Rhino.įirst of all I’m going to open up the V-Ray material editor and I’m going to look at how we apply a texture to a standard material. Let’s first of all take a look at how we can apply a simple texture to a V-Ray material inside a V-Ray for Rhino.
Then we’re going to look at how to map and control these textures which is primarily controlled from within Rhino and then we’re going to take a look at creating decals in V-Ray for Rhino.
