Matinee turns black my textures.

Hi all;

I have one event track and one float material param added to my matinee sequence. There are two meshes linked to the matinee. All my meshes look good before install my matinee in the level but, when I finished to tweak my matinee and rebuilt the lighting, my meshes look a black color.

The meshes are in movable mode and have a second UV channel for lightmap. I have tried to rebuild the lighting without the float paremeter and the event track of the matinee and the meshes turn back to the normal color.

Anyone know why it is happening?
