Problem with multiple UVs in max

hi everyone

i have a problem with multiple uvs in 3d max with Normal map .

first let me talk about the project that having this issue

i model a charcter and set uv 0 0 for the body and 1 0 for the head

i used SSS+ skin shader in mental ray i used for the color ,spec , refl ( composite map )

to apply two texture to the hole body but when i used composite map in bump shader

in give strange image the normal map is applied in some parts only.

i ve used normal bump map in each layer w .

i tried to apply normal map only in the head and tested it works and also for body

but when i used composite map i get the problem is there any way to apply
normla map in multiple uv other then composite map or solution .

Hi akon07! I always work with multiple UV sets so I hope I can help.

You said for the normal map that you used a normal bump map in each layer. Do you mean that in composite, you have "normal bump map" twice?

The way to do it is to have one "normal bump map" in the bump slot, and a composite inside that "normal bump map" in the normal slot with both the head and body maps.

Does that help?
