Hi,
I've been working on this head for about 1 year now, first head that i've ever made anyway... want to finish it soon! but i'm having problem with the bump maps that i've created for each emotion blendshape. I connect one 2dBump node to another by connecting "normal camera" --------> "Out Normal" and then i connect that 2dnode to the Bumpmap shader in the fast_skin_maya1 shader. Then i use this expression on the 2dnode that is connect to my (eye brow up) texture, "Browsout_Up_Bump.bumpdepth = clamp (0, 1, FaceShapes.BrowsOut_up * 1) the texture is put on the blendshape when i slide the blend shape slider to 1. But when i have multipule textures connect such as for my squint texture, it becomes really light (u can bearly see the texture) I have some pictures here:
This is picture part of my shader network:

This is image of all the bump map shader connect (two nodes) but this is the neutral face not blendshapes used

This is with the eye brows up

This is with eyebrows up and bumpmap

This is when i put the setting in the expression up to "50"

This is just a blinn shader with color map and bump map (u can see that the bump isn't really working on the other ones)

This is an example of the squit blendshape, and u can barely see the bump map on the sides o the eye

i posted this on the Maya thread but it seems no one wants to respond... sry for double posting i thought this might be a better place
