Why does the animation sequence make the skeletal mesh smaller?

I’m importing my model in FBX format, and three files are imported at once: the skeletal mesh, the skeleton, and the animation sequence. When I create a new blueprint, add a Skeletal Mesh component, and assign my animation to it, the animation makes my skeletal mesh about 10 times smaller! Why is this happening? I applied all transformations, exported everything correctly from Blender, and nothing was scaled down there. But here, this problem occurs! Please help me figure it out!

Hello,

When you say smaller, is it scaling your Skeletal mesh or is it squashing your mesh? Would you be able to provide some photos and more details?

Thanks,

It usually happens because the animation has different scale data than the original skeletal mesh. Check your import settings or animation retargeting — it might be applying a root scale or bone transform that’s shrinking the mesh.

This usually happens when the animation and skeletal mesh are not using the same scale data, even if Blender looks correct. I’d check the armature/root bone scale, FBX unit conversion, import scale, and make sure the animation is imported against the exact same skeleton as the mesh. Also try applying transforms to both the mesh and armature before export, not just the mesh.
