TUTO: Simple Spotlight setup Tweet

[Renart]

Hello!

In my daily work I really need to use light with a bit more control than the basic geo that we have.

So I made this simple setup using my poor knowledge in Maya.

It's basically a Cone with a light inside and some custom attributes.
If you selection the yellow arrow, you can control the Cone Radius and FallOff. of the light.
There is also a simple fog box attached with a density control, nothing crazy.

Please feel free to improve it ! I'm not a Maya expert so it's pretty rough.

Cheers!

(This wasn't using the latest Octane version, on Maya 2017)

This is an interesting spotlight rig,
the strength is vey high I suppose this is a scene scale issue, in which unit is it supposed to work ?
Also I would have used a meshLight instead of an Octane light node in the rig,
Octane Lights nodes have a terrible implementation, with many limitations and the worst locator ever.

I always wanted to make rigs for each maya lights type (spot, area and point light),
but I would use the Maya light itself as a locator and source of values, my aim will be to have the exact same result in Octane as in viewport 2.0,
like it's done in Arnold.
I guess this will help, thanks !

Yeah you are probably right about the scale.

But what you're suggesting will be perfect at the end. I don't really have the time and the skill to do that properly, I really hope the dev team will implement this properly one day...

The "dev team" is only one man (JimStar) working only part time on the plugin

Thinking more about this, the better way to do it, is to support Maya builtin lights trough OSL, hopefully Octane 3.1 will help for that.
