I wanted to write a message about strange message from Ogre.log, but now I see what it is, but let me say I don't like that behavior of ogre3d :
Hello what happened to command parameter light_specular_colour ? I keep getting errors like
Code: Select all
20:51:51: Error: ScriptCompiler - invalid parameters in DCW0000.material(25): Parameter called lightSpecularColour does not exist.

Example material code is like that :
Code: Select all
param_named_auto lightSpecularColour light_specular_colour 0.0
Example shader :
Code: Select all

vec4 crossMap = texture(crossmap, out_UV2.st);
if(crossMap.r < 0.00005)
{
vec3 texelColor = texture(decalmap, out_UV0.st).rgb;
if(diffuseSurface==vec4(1.0,1.0,1.0,1.0))
result = lightingTerm * texelColor;
else

}
else{
if(diffuseSurface==vec4(1.0,1.0,1.0,1.0))
result = lightingTerm * crossMap.rgb * seatColor.rgb;
else
result = lightingTerm * mix( crossMap.rgb * seatColor.rgb,diffuseSurface.rgb,0.5);
}
color = vec4( result.xyz, 1.0);
}
That way I got the error above, but shouldn't such a mistake be just a warning or not reported at all ? That way I loose other errors information... why does the GLSL compiler or material compiler ( or both ... ) behave like that --- reporting ONLY the first error ? ..... Whose choice it was ? hmm
