Also, since I'm used to seeing real-time rendering in apps like Blender and Unity, not seeing the results of my shader adjustments in the 3D preview was frustrating and made me think I had made mistakes.
I realized then that this tutorial is more of an intermediate tutorial despite the "Basic" in the title. At one point, I somehow removed something and the entire scene was blank, so I started over. Shaders are more complicated and in the TerraTuts tutorial, I found myself going back over the adjustments several times to get it right. Getting the terrain to look the way you want it to is very easy using Terragen's numbers and sliders. They also recommend using a lower-quality image (by adjusting normal render settings) to check your work periodically. Planetside recommends that you use the normal renderer for Objects and Terrain, but for Shaders, Clouds and Lighting, use the Ray-Traced renderer. You have the option to use the normal 3D renderer, which is pretty good and fairly fast, or a Ray-Traced Preview, which is slower but shows more detail. Lastly, Terragen 4 uses your computer's CPU to render in the 3D Viewport. This puts the camera at the view in the preview window so that you can render from this perspective. One fact that is repeated in all tutorials is to click the "align the view to camera" button at the bottom of the preview window. Navigation is primarily through keyboard shortcuts, but there's also a circular button on the top right of the preview window that opens up to a tool that allows you to move the camera in any direction you like. More on the Painted Shader tool later in the article. Near the end of the tabbed 3D preview window are the Painted Shader tool and the Measurement tool. Depending upon your CPU speed render times will vary. The 3D preview (all rendered from your CPU) lets you choose a variety of render settings including a ray-traced preview, adding atmosphere and lighting (or removing). It is recommended to turn off this view as it requires advanced skills with nodes to use. You then have the main 3D preview window and the nodes window beneath it. Both numerical and slider adjustments are featured. This is just above the Options panel on the left side of the main interface. You also have the Scene Elements list which shows all of the various parts of the scene you are creating. This is where you make adjustments to the Shader (and all the other Scene Elements). It's easy enough to use by anyone regardless of experience, so you can start editing your existing projects or create new ones from scratch to use in presentations, video game design and more.When you select a Scene Element like Shaders, a corresponding Options panel opens up on the left-hand side of the interface. On an ending note, Terragen is a practical application with powerful built-in render engines and an abundance of creation tools so you can design custom environments or generate high-quality previews of existing terrain data files. This determines the render starting position, which is delivered in a different window and can take some time, depending on quality specifications, but the output leaves nothing more to be desired. Multiple cameras can be set up so you can quickly switch from one to another.

If your machine is powerful enough, the update is done flawlessly. Powerful render engines generate high-quality previewsĪll of your changes are updated in real time, with the application rendering the image little-by-little. Identification is easily done through the dedicated side panel which provides quick access, but they can also be found in a clever map display, with colors to differentiate each type. In addition, the application also gives you the possibility to import real terrain data files to analyze and enhance.Īll of these tools are cleverly stored in tabs and let you create and manage objects, terrain, shaders, water, atmosphere, lighting and cameras. Using a wide array of object generating tools, you'll be able to create just about any environment you can think of. Thorough creation tools organized in categories This is amongst the only aspects you should worry about, the application being cleverly designed and intuitive enough to get you quickly up and running. Note that the application comes equipped with advanced techniques and render engines in order to provide high quality output so make sure your rig can take all of it. It's also the case when creating environments for modern video games and apps like Terragen give a helping hand in this regard. Data is processed and rendered with specialized applications. Mapping out our surroundings is now a matter of using sophisticated machines to gather data and build up virtual representations.
