Child meshes animate, but their textures dont

Hi there.
I created an elevator from several pieces (metal plates and etc), created an empty object and made it parent for above mentioned pieces. In Animation menu i created animation of elevator moving down. In the scene it works fine, but while playing only gate part is moving but others stay in their default positions. The player in the elevator cant exit it (looks like meshes of all pieces animate but textures dont)

I tried to recreate animations and the model itself completely, but it didnt help.

Sorry for my english. If you need any clarification ill do my best.

Thanks in advance

Problem solved, uncheck “static” in inspector
