To make the next step easier lets also setup a viewer node. Next go to add > search > keying and then Connect your image or footage into the image input of the keying node. First go to the compositing workspace and enable use nodes if it's not enabled already. This is another compositing effect that is actually fairly simple to setup. In blender we can isolate the color of the green screen and set it as the alpha channel to isolate whatever is in front of it.
The green screen acts like an alpha channel in an image. Sometimes we just need to do a classic green screen effect in Blender. Connect the text scene to the second input. Go to add > search alpha over and then connect the main scene to the first input. In the compositing workspace go to add > search > render layers and set the scene to our text scene. Now if we select our main scene again at the top of the window we can go to the compositing workspace. Create a camera and place it in the scene as well as the lighting and world material. Once we've created the text we want go to Render Properties > Film and enable transparent. We can press TAB to enter edit mode on the text and then use it like any other text editor. Go to the top right of the window and on the scene dropdown create a new scene then go to add > text. To do this we can either use View layers or multiple scenes.įor our example lets use multiple scenes. Then get our text as a separate pass and use the alpha channel to combine it with our Render. The easiest solution of these two is just to create our text using the Blender text editor. Note that for both solutions we'll need to do a little work outside of the compositor to create our text. Let's dive in and explain each a bit further. Can really highlight just how fast an object is moving as well as making motion look more natural.Another very useful effect especially when we need to store transparency information in a format that doesn't support it.Great for going in and fine tuning materials.A great new feature to take control over your lighting even after rendering has finnished.Can make our renders look more realistic and add another bit of imperfection to often overly perfect looking renders.A common but very useful compositing that we can use to clean up our renders.Can help highlight just how bright a light is and make bright spots in a render look more natural.Fairly simple but often we want to add text to our render, and it can be a bit weird to setup.Gives lights a more cinematic look and emulates the artifacts lights create in photos.Can add a nice bit of imperfection to the often overly clean look of renders.Great for tuning the colors of our render to be exactly where we want them or to set the tone of the render.A soft circular dark edge on an image that looks nice and helps guide the viewer's eye.So, let's take a look at some of the post-processing effects at our disposal. From a subtle vignette to a nice bit of bloom to brighten our render. There are a wide variety of effects we can use to spice up our renders in Blender.
