COPYENTITY b3d animmesh strange behaviour?

Copyentity a B3d loadedanimmesh works strange, or maybe there's something I dunno.
Those meshes are made by 2 texture, one of them Alphaed.
When duplicating those meshes, only the last looks right. The firsts don't display Alphaed textures...
Tried with other b3d models too...

Include "B3dExtensions.bb"

Function SmoothTurn(Entity,entity2,entity3)
	gMXSpeed = gMXSpeed*.9 - MouseXSpeed()*.12
	gMYSpeed = gMYSpeed*.9 + MouseYSpeed()*.12
	AX# = EntityPitch(Entity)
	AY# = EntityYaw(Entity)
	AX = AX + gMYSpeed
	AY = AY + gMXSpeed
	RotateEntity Entity, AX, AY, 0
	RotateEntity Entity2, AX, AY, 0
	RotateEntity Entity3, AX, AY, 0
	MoveMouse GraphicsWidth()/2,GraphicsHeight()/2
End Function
