Leverage the Real-Time 3D Draft Preview that uses the faster Real-Time Engine (RTE) renderer to preview in real time the changes you make to your 3D scenes. It is an engine built to assist animation workflows by speeding up real-time playback in heavy scenes. The renderer runs on GPU. Unlike other renderers in After Effects, RTE is only intended for draft quality and not final output.
Unlike the older Fast Draft that has to be accessed from inside a few dropdowns, Real-Time 3D Draft Preview can be accessed from a single Draft 3D button located on the composition toolbar. When you add 3D content to your composition, the 3D tools appear in the Composition panel toolbar. You then need to enable Draft 3D.
Using the Real-Time Engine, it speeds up play-back times for 3D projects. Get instant feedback while working on your designs, cutting down the lag time for improved preview playback speed. Note: 2D content needs to be cached before it can be played back in real time, but you can make 3D changes such as adjusting position keyframes without needing to re-cache.
When you have 3D content in your comp, the Draft 3D button appears in the Composition panel toolbar. Select the button. to turn on Real-Time Draft 3D Preview. What it does is, After Effects starts to use the Real-Time Engine renderer to show you in real-time the changes/updates you make to your 3D design. This experience is seamless and faster, thus avoiding lag during preview.
A ground plane is a horizontal plane of projection that gives you a sense of perspective and space within your 3D scene. It visually orients a user in 3D space. It gives a reassuring grounding to a 3D space.
To use it, ensure that the Draft 3D Button is enabled, and then switch on the Ground Plane button next to it. This tool is helpful in keeping everything in your scene in perspective and proportion at a glance.
- The closer the objects are to the ground plane, the easier it is to understand their relationship to one another in 3D space.
- The ground plane grid progressively scales as you dolly in and out of the scene.
- The scene center locator axis is present in the centre of the comp view to give you a sense of X,Y,Z direction.
To make your 3D designing more convinient and time-saving, the composition panel displays only the most used features. 3D options are now contextual and won’t get in your way when you don’t have 3D layers in your comp. Settings that are no longer accessible from the toolbar, such as Pixel Aspect Ratio Correction, can still be controlled from the Composition window menu.
This enables you to work seamlessly across both 2D and 3D, with the appropriate UX to guide your design work, without having to constantly enable or disable a large number of settings as you switch back and forth.

- The Draft 3D button enables or disables the Real-Time Draft 3D renderer. This feature was previously enabled by changing the Fast Previews mode to Fast Draft. Note that the real-time draft 3D renderer is different from the Timeline panel “Draft 3D” control.
- The 3D Ground Plane button enables or disables the 3D ground plane when Draft 3D is enabled.
