How make light ignore trasparent mesh I trying to make mesh for hair  with transparency for BGE but the light is reflecting the entire model including the area that supposed to be invisible,the only way i find is unmark specular in the light, but i wish to find a better way because a want to use specular.
You need to drag the Specular Intensity in the Material tab all the way down to zero. And enable Intensity under the Specular in the Influence tab of the texture, as seen below.
