Texture keyframe problem


I’m facing a weird problem.
I have a character (composed of planes), all parts are loosed and called “O Worten Face”, “O Worten Right Arm”, “O Worten Left Leg”, and so on… (Same thing for the textures)

There’s only one special thing, for the “O Worten Face” there’s different textures I want to switch, just to fake the mouth movement (different draws of the face…)

When I add a keyframe to a texture of O Worten Face, Blender automatically add the same keyframe for other textures! Which is annoying because it make them disappear… (The mouth move but the rest of the texture disappear)

Thanks in advance! I’m still searching but i’m lost… :frowning:

I just did another material and it works now
