View Full Version : Which Side is Emissive??

02-20-2012, 12:24 PM
When I create a plane in the model to be emmisive and shed light on an object... If I pick 1 side to emit light is ALWAYS facing the wrong way and I would have to do 2 sides to get light on my object.... How can I change which side emits?

I am sure it is a lack of knowledge on my part....

You can't change which side emits, instead just rotate the plane so the emissive side is facing then model.

The "front" side of an emissive surface it tied to the normals direction of the surface the emissive material is on. Usually, normals can be flipped in the CAD package. The most painless method is to do what John G suggests but if you want to try and remedy it in CAD, try flipping the normals prior to export.
