vray light bulb ignore light normals / cant see how this affects the scene

[jonathan Evans]

I have set up quick teapot render in vray . I was checking the effect of ignore light normals. I have unticked and ticked the box i have a standard indoor sphere light set up 1 bulb at temp 2300.

 

As any one any example of images of how ignore light normal effects the scene. In my scene this has not made any change.

 

 

attached to see example

cheers

Try your same experiment using a plane and you should see the difference.

 

https://docs.chaosgroup.com/display/VRAY3/VRayLight#

 

A sphere has a surface normal in all directions and this option tells the light to focus its emission towards the surface normal or not.

 

I have not tested this, but that is what the help menu says.

Ive read the help menu. I read the description when i tested it wasnt apparent . I try the plane instead as advised

cheers

Let us know... I've never cared enough to investigate.

I am trying to look for the option in my Vray, but I can't seem to find it to test it.

 

I am using Vray 3.0 in 3dsmax Design 2014.

using ignore light normals with vray light plane. The box was ticked with a plane . The room became brighter in all areas. From the position of the camera. i have over laid image 1 and image 2 to show the difference . Image 1 has the box unticked not using ignore light normals. image 2 is using ignore light normals .
