I'm a little confused to why you would want to change the "
.mat" file, but to do that you just open it up (Same directory as the Grunt, called "
servant_grunt.mat") and change what is under the "
Diffuse", "
NMap" and "
Specular" sections.
<Material>
<Main DepthTest="True" PhysicsMaterial="Default" Type="SolidDiffuse" />
<TextureUnits>
<Diffuse AnimFrameTime="" AnimMode="" File="servant_grunt.dds" Mipmaps="true" Type="2D" Wrap="Repeat" />
<NMap AnimFrameTime="" AnimMode="" File="servant_grunt_nrm.dds" Mipmaps="true" Type="2D" Wrap="Repeat" />
<Specular AnimFrameTime="" AnimMode="" File="servant_grunt_spec.dds" Mipmaps="true" Type="2D" Wrap="Repeat" />
</TextureUnits>
<SpecificVariables>
<Var Name="HeightMapScale" Value="0.05" />
<Var Name="HeightMapBias" Value="0" />
<Var Name="FrenselBias" Value="0.2" />
<Var Name="FrenselPow" Value="8" />
</SpecificVariables>
</Material>
I mean it's already set up for you, so I would think the only thing you would be interested in changing are the actual "
Texture.dds" files already associated with it.
