A mesh is treated much the same way where-ever possible, edges are placed around a mesh to facilitate a similar end result. The principle involved here is the same as if you were to cut a cardboard box down one side, laying the resulting top, bottom and sides flat on the ground so all the parts of it were spread out. Rebuilding the UVW map after creating edge splits in the mesh, not idea, so further editing is needed to correct the distortions To change " Map Input" mode, press " F6" to open the " Texture Buttons" and find the " Map Input" panel (as shown below), then click on the button titled " UV" you may or may not notice a change on the mesh itself but you should see a change occur to the material preview window panel to the far left side of the Texture Buttons window, this indicates that we're using the correct 'map' type.Once done, we can then move on.
If on switching to Textured mode the chair doesn't look right or looks more distorted than expected that may be because the object is using the wrong " Map Input" mode - what this does is instruct Blender to display textures using different types of co-ordinates relative to the object itself, so if this is left on the wrong setting the image may appear wonky despite being applied to the mesh correctly (as will be done further down the tutorial). Zooming in on the chair object (MMB scroll), the image can be seen displayed on the mesh using the initial UVW map made for it. Next we need to assign the texture to the UVW map so we need to move across to the UV/Image editor view. From the list that appears, select " Unwrap", you should see a pink shaded square appear in the UV/Image Editor view on the right (as shown below) that's the UVW map created, more work is needed but that will come later. Once done, press the " U" key to open the " UV Calculation" pop-up. To do this enter EDIT mode ( TAB) and select all faces using the " A" keyboard shortcut we used previously when making the chair (it doesn't matter at this point if other faces are already selected as we need to select them all). Now that the layout has been set up we can turn to adding the UVW map to the chair. Showing the " UV/Image Editor" alongside the 3D view, where the texture and UVW maps will display, after changing " Window Type" Adding a UVW map to the chair ^ RMB click on the boarder between each zone (marked in 'red' below) and select " Split Area", a dividing line will appear that can be moved up or down indicating which screen is to be divided go ahead and divide the upper work area of the layout so it approximates the image shown below.ĭesign note: the border can be moved once the divider has been placed by LMB click-dragging it left/right - the direction the border can be dragged is dependant on the orientation of the divider itself 'vertical' splits only allow left/right movement, where-as 'horizontal' splits will only allow up/down movement.Ĭlick the " Window Type" button in the corner of any toolbar header to change it to another 'type' of view - " UV/Image Editor", " Action Editor", " Audio Window" etc. To make this process a little easier to do, we're going to split the work zone into two sections one for the mesh object, the other for the texture image and UVW map display. The modeled chair has a material with a texture slot that has an image associated with it waiting to be shown on the model once a UVW map is in place Changing Blender layout - splitting screens ^ A Texture should be associated with the Material and a texture Image (bitmap) assigned to that - although this won't be visible at present. This should be the base chair mesh with a Material assigned (with or without a Diffuse colour change from the default light grey). The process of adding a (UVW) 'map' to a mesh is called or referred to as "unwrapping", and is usually straightforward to do, especially since Blender has some handy and useful tools to make 'solid' (as in, 'good') UVW maps.įirst a reminder of progress so far. So what is a UVW 'map'?Įssentially it's a set of co-ordinates or information needed by both Blender and other 3D rendering (game) engines that tell them how an image is supposed to appear over the surfaces of a mesh, whether our chair looks like it's made of wood, metal, stone, and so on, this is called a 'map', or 'mapping'. Once the material, texture and image data is set up and sorted out the next step is to UVW 'map' the object so that texture image/s can be seen on the mesh. To get fully working models that can be used in games and 3D media projects we now need to turn our attention to UVW maps so objects display on their surfaces the images associated with materials.
