I’m using the latest version of blender (2.46) and was needing to know if its possible to use a jpeg image as a texture for just a portion of a cylinder object (not the entire cylinder the same texture). I was thinking this might could be done somehow using vertex groups. Could anyone tell me the steps I should take?
You don’t need to use a vert group, you can simple apply different materials to different faces in Edit mode. First make sure you have applied a material to your whole mesh, then in Edit mode with the Edit panel open (F9) select the faces you want the new material to be used on and then under “Links and Materials” Click New and Assign. This will create a new material and assign it only to the selected faces.
You can use the same steps I outlined before and select only a single face to apply the new material to. Once you have the new material, you can load your image as a texture for that material.
To load an image texture, press F6, click Add new, set the type to Image and at the far right click Load and select your image.
There are at least two other ways you can accomplish similar results. One is to load the image texture, add an Empty to your scene and use the Empty as Map input for the texture. This allows you to move the texture around on your model by moving the empty.
The other way, would be to UV unwrap your mesh and apply the image only to the face your want.
Thanks for your help. I did the steps you mentioned in your last post, but for some reason it keeps applying the textured image to the entire object (even though I’ve only selected a single face). Any ideas what I may be doing wrong?
You likely did not already have a material applied to this mesh. The first material you add will apply to the whole mesh, you can then add another and then press Apply to apply the new material to only the selected face(s). Argh, I wish the Wiki was up today, it has a great step-by-step article with pictures that describe this.
It seems like I’m close but not quite there. I can get the single face of the cube to change to the new material color, but when I load the texture image it colors the entire cube ( I made sure to first apply a material to the entire mesh). Is there a way of changing the link between a material number and the texture?
I should have read your post a little more closely. I went back and performed each step slowly, and noticed I had missed something that you said to do. Now it works! Thanks for your help!
Glad it worked. My next step was going to be writing out better steps for you. I tend to rely on the wiki for these things, so when it is down it is troublesome.
One more question, when I use the image as a texture (which is an image the word “USA”) it repeats itself on the face of my object. Is there a way to have the word “USA” only show up once?
When you load the Image Texture (F6), there is a tab labeled, Map Image. By default the Repeat button is pressed. Choose either Clip to clip to just one copy of the image or Extend to extend the border color of your image.
