Question regarding light.

[sayan751]

Hi,

I have a question regarding use of light. In my scene I have a HemisphericLight:

var light = new BABYLON.HemisphericLight("light1", new Vec3(0, 1, 0), scene);

The result can be seen in the first attachment, "2015-10-17_18h36_41.png" (with a white light).

Doubting that this is caused by the specular of light (this is my referrence: https://github.com/BabylonJS/Babylon.js/wiki/06-Lights), I have added a specular color as following:

light.specular = new BABYLON.Color3(.00000000000001, 0, 0);

Which seems to be working as can be seen in the second attachment, "2015-10-17_18h38_13.png".

 

My question is this the right of doing it? Or I am completely on a worng track and it is not because of light, I am having a bright white patch of light in my scene. Need your expert advice on this.

 

Thanks,

Sayan

Hi,

Yes, this is caused by the specular definitions. I can only assume this object is like a ground mesh, flat on the y axis. It's not necessarily because of the light's definitions. The standard specular color of the standard material is white (1,1,1). Try playing with the material definitions of the mesh, especially specularColor (a Color3 object) and specularPower (a number)
