However, many of these sites are overly technical, requiring knowledge of satellite names and confusing geography terms to find the imagery you want. The problem is finding these heightmaps.ĭepending on the location, you can find map data from various places. Once in Blender, I can use the luminance values of my heightmap to drive the vertical displacement of my terrain. I’m specifically looking for a grayscale heightmap. It does not store any personal data.While I recommend watching the video as it’s laid out in a step-by-step follow-along process, you can find the abbreviated steps below for a quick recap of the tutorial, if you get stuck.įor the first step, I need to get some real-world map data.

Reminder: the Background or Reference image will not be rendered with your scene. If that particular image ever moves or is deleted from your machine, Blender will always know where to grab that file – the copy within the. blend file, essentially duplicating it, storing it and referencing it within that. The bottom file field is the “pack” option, which will “pack” that image into the. The Source dropdown gives a few image type options, including Movie. In the section below that, you’ll see the option to change the image file if needed. The Orthographic and Perspective checkboxes toggle which views the image is visible in. “Side” will set the direction from which the image is visible: only visible from the front side, only visible from the back, or both. The Default setting will treat the image the same as any other object and adjust its visibility based on its position in the scene. The Depth setting determines if the image will always display in front of or in back of the object. The Size and Offset settings are basic scaling and positioning settings. The top dropdown labeled Display As will change the type of object that represents the Empty. This tab is an “Empty” tab because the image is added as an Empty – essentially a placeholder, point of reference, or other non-rendered object.Ĭhecking Use Alpha will give you the ability to adjust the transparency of the image, which can be useful for overlaying blueprints or floorplans over your model. To find the settings for the Background or Reference image, select the image and click the red picture icon in the panel on the right side of the screen. Alternatively, with the Background image selected, press N to pull up the Transform tab, which shows the object’s Location, Rotation, and Scale. NOTE: When rotating a Background image, be sure to include the axis as well as “90” to rotate 90 degrees. Toggle through the views using, 1, 3, and 7 on the numberpad. The Background image option is similar in that it adds an image and can be scaled, rotated, and moved with the S, R, and G keys, but it is only viewable in the top, front, or side views of the scene. A Reference image is an image that is visible in the scene and can be moved and manipulated like a plane. When you hover over it, you will see two options: reference, or background. Scroll down until you find the Images tab. To add a reference image, hit Shift + A to bring up your Add menu. It is often helpful to have reference images like sketches or photos to use when starting to model an object. To render an image, try using Add Image as Plane. NOTE: Backgrounds and reference images will not appear in the rendered scene. Manipulate the images as needed using the S, R, and G keys.Background attaches the image to the current view (front, top, side, etc.) and is only visible from that view Reference will add the image as a plane object within your scene, edited like any other object. Hover over “Image” and select either Reference or Background.In the 3D viewport, press Shift + A to bring up the Add context menu.
