I see in this Topic Embree in Action some mesh light.
How can I create the same within Embree ?
I try to create as many "TriangleLight" as my mesh contains, but the render get impossible slow, because each triangle is a "Light", and shadow is compute on it and take too long.
There must be a better way in Embree to do it, but I don't see any.
Can someone light me on this ?
