Sling gun looks weird when cloaked

The cone may be unavoidable, but why is the whole thing white? The cloak part of the shader probably reads something from tex2.

	vec4 texColor1 = texture(texture1, myUV, textureLODBias) * 1.0;
	vec4 texColor2 = texture(texture2, myUV, textureLODBias);
	texColor2.rgb = texColor2.rgb * 1.0;

Put this in the shader and it looks like this:

Why is the gun behaving as if the textures are white?
