Frame Rate
Before getting started, it’s important to check the frame rate. Decentraland’s animations must have a frame rate of 30 fps. The rig file provided probably has that set up, but since Blender’s default value is 24 fps, it is best to double check before starting (a wrong frame rate will affect the speed of the animation). That option can be found in Output Properties (the printer icon) under Format, as shown below:
Make sure the framerate is set to 30 fps before starting.
Pose Mode
In Blender, a rig can be viewed in three different modes: Object Mode, Edit Mode, and Pose Mode. Animations can only be done in Pose Mode (in that mode, controls have colors). With the rig selected, you’ll find that option in a dropdown menu, at the top right.
