Direct lighting still visible in reflections even when it's disabled #2861

Hi, This issue is visible when non-physical lights are used. There are spot lights in this scene but direct lighting is disabled. Nonetheless shadows and lighting is visible in reflection: image

I think it comes from this line in on_scatter function in ptlightingengine.cpp

if (m_params.m_enable_dl || vertex.m_path_length > 1)
{

Visible in reflection and direct lighting are two different things right ?

Yes, I think the definition of direct lighting is lighting provided from a source without reflection from other surfaces.

If you set the object visibility flags for shadow, specular and glossy to off for the yellow pot you should have no reflected image visible.
