Intensity Falloff for Octane Lights Tweet

[promity]

For architectural visualization, a feature such as intensity falloff is often in demand.
It would be very useful to have something similar for Octane light sources, as it is implemented in LW.

There is a nice video by Lightwave guru that my help you with that

Hi promity,

Beware that by default, Octane is based on the exponential "quadratic light decay" (inverse square law) as it is the plausible decay go-to option in all offline renderers.

Regarding Architecture Visualization, most if not all light "effects" should be currently possible, with or without workarounds (Octane's roadmap contain upcoming new light features).
Inspiration from real-world photography and/or cinematography lights and lighting set-up are great resources helping on the foundation of "shaping with light".

Thank's, interesting type but not exactly what i'm looking.
What I mean is the ability to adjust the scattering of light from a light source without changing its size and brightness. How it is implemented in the native render of the LW.

Do you have a link (documentation, video, etc) about Lightwave's light feature(s)?

I am not entirely certain I understood what you are looking for, but could it be the "normalize" options in Octane? There are two I can remember at the moment, one in the generic area-light attributes and one in the Spotlight Distribution node (this one has been rather recently added).

What do you mean by "scattering"? Did you, perhaps, meant "beam spread"?

The fact is that even if there is a similar function in the current state of Octane, its use is far from being as convenient and simple as in LW. In Lightwave, it is enough for me to set the value I need in meters and I am sure in advance of the result. With Octane, everything is not so easy in this matter.
