Hello,

Hi, I'm wondering if anyone can send me a link or suggest a product which will

include the Iray ghost light factor script. This is used to prevent an emissive/mesh/ghost light

from being shown thru any reflective surface like a mirror or shiny floor/wall surfaces.

You don't need anything extra for that. Starting from the

Yes, both the tone mapping and the Environment tabs of the Render settings offer adjustments that can come in very handy. About the exposure level control, the easiest, straightest way is just adjusting the 'Exposure value', which is effected by the next four settings: 'Shutter Speed (1/x)', 'F/Stop', 'Film ISO' and the 'cm^2 Factor'.

The ghost light is still appearing in the mirror reflection.
I already applied the script then chose to NO to Iray visible in Primary Rays.
Pushed the IGL Factor to 250 but STILL visible in the mirror.
Is it something to do with the mirror asset perhaps?
Maybe it's an old asset?

What if you make the Ghost Light Factor even bigger? I recall having to crank this really up some times for getting rid of the reflections. About the possibility of the mirror itself being too old, have you checked which shader it uses? Really old assets used RSL shaders as opposed to MDL ones (like Iray Uber Base).

Just make a mental note to yourself that Exposure Value is a post render process and does not always result in a better image. At least that is the way it was described to me by one of the DAZ gurus that post videos on YT. And he should know something about that.
