One-Sided Emitter

[ronly2460]

HI,

I would like to use area light, but one-sidded. By default, light comes from both sides.

Would it be possible?

Thanks in advance.

Hi @ronly2460

The area plugin should only emit light on the "exterior" of the shape. The "exterior" is defined by the shape's normals.
So, by default, it should already be one-sided.

Could you share with us a minimal reproducer where this is is not the case ?
