Is it possible to preview the animation sequence on a Sprite3D node in the 3D editor window? The sequence I have is a single texture with 6 frames for a steam effect. It works, but I can only see it when playing the game - making iterations difficult.
You could play the AnimationPlayer if that’s how you are advancing the frame counter. You could change to a AnimatedSprite3D, or even set up a small particle node to use this sprite sheet.
