The following are some bugs I encountered while using Model Engine to create skill effects.
I added multiple textures in Blockbench and set the animation scale keyframe interpolation to "Step" to cycle through each texture to create a flipbook animation. In-game, switching models this way causes delay, which makes the model flicker and even drop frames. In addition, when the animation's scale interpolation mode is set to "Step", the position interpolation mode is also affected and becomes "Step", causing the animation to stutter.
