VRayLight - Specular vs Reflection

[Morne]

Hi all

So whats the difference between the "Affect specular" and the "Affect reflections"?

Isnt the specular actually just the reflection, so it's the same thing?

The specular is really only a fake representation of the physical light source. The reflection itself is a real reflection of the physical light source.
So to go 100% photoreal, you shouldn't use any speculars at all. Although they can be useful sometimes (with low-gloss materials like concrete), I tend to turn them of in the material, especially when doing glass, water, chrome etc.

So, to conclude:
Affect specular = the light source will generate a specular to be visible in your objects.
Affect reflections = the area light will be visible in the reflections of your objects.
