Directional light

[fabrizio_s]

Hi,
in the next version is it possible to have this feature on the lights panel?

Take a look at this video from 15.50 to 17.00 min.

Hey there,

i saw the video and thought the same thing. It would be nice if this was a bit easier,but you can get the same result by pluging a Falloff Node in the Distribution slot of the Texture Emission.

Try these Values:
Minimum Value: 1
Maximum Value: 0
Fallo Skew: 0.1

Maybe someone has got a better idea or knows a better workflow.

Cheers!

did you actually try your suggestion, this looks like he said, like there was a cone geometry.. you suggestion would only change how the light looks, not the emission much.. didn't try it, but manipulation of light is painfully limited

- man... so this is what happens when you don't listen to your programmers advices - he goes on and does it himself
- do you know octane is suing fstorm for "similaritires" so now even if octane wants to do this - it would be highly hypocritical of them - "stealing" back ideas..
- what this is doing, is convincing more and more octane users to take a look at fstorm

- and octane/otoy should hire more programmers, not lawyers and waste everyone's time - 3dmax plugin hasn't been updated for months now..
- also offer a lot of money to Karba/Andrey Kozlov so you can buy his software and hire him to work on parallel on it .. but you won't do that.. you will spend a lot of time and money on lawyers instead of giving users a better user experience ..

I don't see how adding a directionality parameter to lights is hypocritical or stealing an idea, Vray have this too, I can see you are mad at Otoy for something but don't confuse things by that logic anything that Octane does that Fstorm did first is stealing so Otoy stole the idea of Adaptive Sampling I suppose... If Octane have a better bokeh rendering in later versions I guess they stole that idea too... I also need this feature, I'm tired of making boxes around lights to get directionality by force.

I tried it and i think it works:

Maybe there is a better way, but i think it looks way more natural than without it. As i said, its not as convenient as the fstorm Solution with a degree value. But it's something.

Again, if someone has a better idea or knows how to get a better result i would be happy to learn!

I tried it and i think it works

I just tried myself and I think this is a great solution! much better than making boxes, thank you very much for this tip.

To enhance this further you can add a ColorCorrection and change the contrast to control the sharpness of the edges:

Looks very directional to me! again thanks for the tip.

Hi Hesekiel2517,
thanks a lot for your solution.
I'm trying in rhino but I can't achieve those effects...please, can you show the values of the Falloff (mode, min, max, skew, direction)?

These are my settings. I found that there is much more control if you add a gradient. But you can also use the Falloff-Skew directly.
