Hide Lights/Emitters in refractions Tweet

[joshstudebaker]

Using octane in C4d.

So i have some car headlights, and in order to get the "look" i want reflecting in the headlight interior, i need to place an area light inside the headlight. That means that the area light is behind the front glass of the headlight. When i do this however, the square plane of the area light is visible in the refractions of the front headlight glass. I've tried using the octane object tag to disable camera visibility, but this has no effect when viewing a light through a refraction. Is there really no way to disable camera visibility of a light when viewed through a refractive object?

Thanks!

Why don't you play with light tag parameters? Don't you use "Octane Arealight" preset from LV/objects menu?

Yes, but there is no option for hiding the light SOURCE from refraction. Octane seems pretty limited as far as tools to do these kinds of things.

You can hide it from camera and refr/refl by opacity.

Hi Aoktar,

Posted about this in the c4d section and in the general.

Ive already shown that if you turn both Opacity and See in Camera OFF, the light becomes Irelevant, its as if it wernt there.


Instead, what I think we are hoping for is an OBJECT-less illumination effect.
Where you can light objects and hide the SHAPE of these objects without messing with the actual lighting. But it seems that the problem with area lights, is that they take forms of Emmission objects, instead of a light with no object affiliation.


Right now there is no real option to exclude the object illumination from reflections or refracted objects without turning off the light completely.


Turning off Opacity acts as a main controller for everything. So that in itself is pretty useless, besides fading the actual object.
General Visibility along with Camera visibility off gets us half the way there, but I think adding a Blur option for lights in reflections might be nice, or just overall adding in an option for turning off being seen in reflections/refractions per light object.

why don't you zero out the opacity in your emissive material?
this way illumination is provided but you don't see the light (no pun intended).
