Specular head. Body, not so much...

Hi folks,

I am new to shaders so I have been practicing! Loading my art into the demo TGEA and comparing my results around the 'widely varied' lighting in that mission.

Can anyone help me figure out why my body isn't getting specular light?


No problem getting Normal maps on all my body parts and clothing. But then I noticed my char's head seems to take specular settings and use them properly.

Using a bright blue/purple to show up clearly.


Specular is working on the head of the static mesh version too.

I have been making tangent based normal maps in ZB2 Zmapper, trying a few of the many settings, reading as I go. Even managed to improve the seams on the normals... But no matter what I do I can't get the specular effect to fire up on the 'body'. The body is 1 UV group but many mesh groups (for hiding), but the entire body calls 1 UV and the normals work fine.

Every thing else in my scene: the SpaceOrcGun, my player head, eyes, mouth have their own material calling a normal and the specular works on them.

I don't really need shiny bodies, just trying to get consistent results.

I've tried a wide array of material script settings, none of which make the specular show on the body.

new Material(Body)
{
   baseTex[0] = "~/data/shapes/SpaceOrc/body";
   bumpTex[0] = "~/data/shapes/SpaceOrc/body_normal";
   cubemap = hikari;
   pixelSpecular[0] = true;
   specular[0] = "1 1 1 1";
   specularPower[0] = 10.0;
};

I've also gone back and tried embedding spec maps (from crazy bump and xnormal) into alpha channels of both the diffuse and normal maps.

Always get the same results...

Note: the specularly working parts of the mesh (head, eyes, mouth) all call a .jpg diffuse (with no fancy alpha embedded), while the body calls a .png diffuse (didn't seem to call any texture when I had a .jpg diffuse for the body.)

Any help is appreciated,
