Material Linking

[Marmalade Boy]

Hi there,

Does anyone know how to link materials with different texture maps? I am using a Daz3D model which has various maps for different parts of the body. The finger nails, hand, forearm, shoulder and Collar are all part of one texture map, the torso and hip are part of another. When I apply the translucent material to the various parts, I can link all the material for those parts because they are part of the same map. When I attempt to link the arm to the torso, the texture map for the torso gets all screwy.

Is there something I am doing wrong or is this something that cannot be done? I thought the linking affected the material (in this case, translucent) not the material and the texture. has anyone come across this issue. I am using KeyShot 5.

HI Rex,

Thank you for the response. Unfortunately, I didn't understand the steps mikeglw took to get rid of the seams. I tried following the below but it didn't work for me; I must be missing something. I have reached out to mikeglw for help. Thank you once again for this lead.

The steps I took were, apply the skin texture to the model, then picked a section and edited the
green color to 56. I then saved the texture under a new name. Then I applied the color from my
materials window ( not the library ) to the other parts of the body.  No seams.

Looks like you've made a friend! Let me know if you're still having problems after trying Mike's solution.

I perhaps was not totally clear on the steps I took to get rid of the seams..

So here goes..

1. Applied the stock skin texture from the library to the models individual parts.

2. I picked one part of the model with the stock skin texture and edited the surface color.
    I reduced the green selection of the colors to 56, and it doesn't matter what you adjust that to.
    I adjusted it down to make it red enough so that the edited skin texture was different enough
    from the stock skin texture in the project windows materials catalog. So I knew which one it was basically..

3. I then applied the color altered skin texture from my project windows texture catalog and applied it to the model.
    And as you do that you will notice that the green seams disappear. Saving the edited skin texture to the library
    turns out to be a unnecessary step.

After doing that, you can then drag and drop the stock skin texture, or any custom skin texture onto the model and it won't
have seams, so I presume because the parts are now texture linked..

Hi Rex

I was able to reproduce mikeglw results but I am still unable to add Daz3D textures to his results successfully. The second I do, the translucent material becomes unlinked and the seams return. 

1. This is a normal render (no Keyshot materials has been applied; this is just plain old Daz3D textures).

2. This is what the model looks like with mikeglw skin fix.  Translucent materials were applied to all parts of the body then I followed mikeglw instructions. All sections appear to be linked; deleting the translucent material from all other parts leaving one material applied to the entire model. No green texture brakes because not textures have been added.

3. This is what the model looks like if I apply the textures back to the various parts of the models after mikeglw's fix, the seams return. Is Photoshop the only way to fix? I get the feeling that the seams would not be an issue if the textures were just one instead of having a texture for each major part of the body.

Yes you are absolutely correct. Combining the textures into one material would solve your problem.
