![]() Keyframes could also not work if you have muted the channel that you have animated. For example, if you change the location of an object, ensure that you select the "Location" attribute from the menu after you press the I key. Moreover, make sure to check that you apply the keyframe for the correct attribute. ![]() Keyframes will only be applied to the selected object or bone. Most of the times, a keyframe not working may be solved by making sure that you have selected the correct object or bone that you want to animate. If the animation type is set to non-linear, certain keyframes might also only be visible in the "Non-linear animation" editor, instead of the timeline editor. If you would like to see the keyframes of all objects at all times, even if they are deselected, simply disable the "Only Keyframes from Selected Channels" under the "View" dropdown in the top-left corner of the timeline editor. Hence, to solve this problem, ensure you've selected the animated object(s) in the 3D viewport or in the object outliner. The keyframe not showing in the timeline can be for one simple reason: by default, the timeline editor only shows keyframes for selected objects. In this case, it may be necessary to go back to a previous save or start a new file to ensure that the animation will play properly. Lastly, it is possible that a problem may exist in the file itself. This can be resolved by closing other programs and increasing the amount of memory allocated to Blender, or simplifying the scene as mentioned above. If the above solutions do not work, it is possible that there may be a problem with the computer's performance. It is also important to ensure the animated keyframes are within the starting and end keyframe numbers, shown at the top-right corner of the timeline. In case this does not play the animation, you can press the "Play Animation" button shown as a right-facing arrow at the top of the timeline editor. The shortcut to play an animation in Blender is the Spacebar key. Changing this one option can make a major difference in render times and can hence improve choppy playback. When working with the Cycles rendering engine, always ensure that the render device is set to "GPU Compute" and not "CPU", as in most cases the CPU is significantly slower at computing. This includes reducing transmission surfaces or adjusting materials with high amounts of subsurface scattering. This includes reducing the number of particles for any particle systems (especially in the viewport), or even reducing the number of polys for a detailed mesh.Īnother way to simplify a scene is by changing textures or lighting in the scene. Simplifying the animation or reducing the number of elements can help resolve this issue. One of the most common reasons is if the scene is too complex or has too many elements, causing the software to struggle with rendering it smoothly. ![]() Similar to a blurry animation, a choppy or jittery animation could be caused due to a multitude of reasons.
