B09- Rendering in Blender
Till now, we talked about Modeling and Animation in Blender. In this post, we will see how we can do ‘Rendering’ in Blender. We get a video or an image once we render it, which we can show to the viewers. Such images or videos are in format like ‘.jpeg or .mpeg’. Once such videos are rendered, Blender is not required to play them.
In order to render a video, we must of-course have some models and some animation to it. To save your time, I have already made a file in Blender. Click ‘This link’ to download the file. Save the file on you computer.
If you double click the downloaded file, it will open in Blender. We will talk about rendering using this same file. Your blender will look similar to this.
You will see shapes like Cube, Cylinder, Sphere etc. They have animation too. The viewport is set to a camera. This is the view seen from the Blenders camera. If you hit the ‘Play’ button from the timeline, you will see the animation.
Now we will try to render it. Notice the Big section at right side of the viewport. We have talked about it. Its the ‘Property Section’. Inside it the ‘Render’ tab is now active. You will fine 3 big horizontal buttons there called, ‘Render, Animation and Audio’. First try and hit the ‘Render’ button. You will find that an image is getting generated in the viewport.
In-fact the ‘image viewer’ is now loaded instead of ‘viewport’. Rendering is nothing but this 2D image generation from 3D models. Blender rendered the current frame. While rendering blender calculates many things like the camera, its angle and the position and colour of lights. etc. You will clearly see the prominence of shadows and shading on the objects.
If you want to save this image. There are options at the bottom of the viewer. Click ‘Image > Save as > and save it to your desired location as shown here.
Let’s have a closer look at the render panel itself. This render panel provides all the important setting for rendering.
Just below the 3 big buttons like ‘Render’ etc., you will find a section for ‘Resolution’. Currently this file is set to have 1920 x 1080 resolution. This is the standard HD resolution. The section at right, shows the frame range to render. This is currently set to render from frame 1 to frame 160. It means, if we render the complete animation, it will be a 160 frames or around 7 secs.
If you scroll down below, you will find settings for saving the output. In the output section, I have pre-typed the filename to be: “//B09-MyFirstRendering-“. This means if you press the Animation button at top, Blender will save the file with this name. Now click the folder button icon next to the name and set the path where you want to save the video. The rendered video file will be save at that location. I have also set the format for the video to be .mpeg so the finished video will be a mpeg file. You will be able to play it from any normal media player.
