Animation scale problem

Hi. i’ve done weapon animation in separate blend. Then i append the animated objects to another blend and scaled it down. When the animation is played in blender viewport everything is OK. But when i play the animations in game, objects are scaled up to their original scale. ctrl+a to apply scale wont work or mess everything. Anyone know how to solve this?

Check if you have a scale key inside your action.

Unnecessary scales are in general not a good idea as there can be some side effects.

Yes i have, but even if i delete them the scale is completely wrong…
