Animation Loop Gap Issue

When an animation loops perfectly in Blender but shows a gap when imported into another application, there are several common causes for this issue:

Possible Causes

1. Keyframe Interpolation: The way Blender interpolates between keyframes might differ from your app's interpolation method.

2. Frame Range Settings: The animation's start and end frames might not be properly set for looping.

3. Export Settings: When exporting from Blender, certain settings might affect how the animation loops.

4. Animation Baking: Some applications require animations to be baked to interpret them correctly.

Suggested Solutions

1. Check Animation Frame Range:

   • Ensure your animation's start and end frames are precisely defined
   • Make sure the first and last keyframes have identical poses for a seamless loop

2. Adjust Export Settings:

   • When exporting to formats like FBX or glTF, check "Bake Animation" option
   • Ensure you're exporting the full frame range of your animation

3. Keyframe Interpolation:

   • Try changing the interpolation method in Blender (Linear vs Bezier)
   • For perfect loops, sometimes linear interpolation works better

4. Add Buffer Frames:

   • Try duplicating your last keyframe to one frame beyond your loop end
   • This can help some engines interpret the loop correctly

5. Check Animation Sampling Rate:

   • Ensure your app is sampling the animation at the same frame rate as Blender

Without being able to examine the specific file, these are general recommendations for fixing animation loop gaps. The issue is likely related to how your application interprets the animation data compared to how Blender plays it back.
