one thing regarding lights...

I have modelled some basic theatre and TV lamps that have a 'bulb' inside them and lenses so that they really do work like a real light... The results should in theory be realistic...

right, I was actually thinking about this today.

Went home from work for some hours to watch some tv and get some food, anyways when i got back one my the bosses came around with 2 physical models in 1:50 of some sets, so i hammered up 2 800w fressnel lamps in a small intermistic set one key and one fill with umbrella.

I need to get a RED head set though, the fressnels are killing me, so heavy and impractical to move around.

Fresnels are relatively light compared to some Profile (typical spot light) lights in theatre.

Then how does one make an emitting material in octane to mimic a light source?

Hey Garrick,

IMHO either by modeling the actual geometry, or by using IES profiles attached to the light source.

Thanks for the reply,

Where do you import IES file with in the Octane program?
Because so far I haven’t found any import options for that file format.

I have a spotlight modeled with materials, that is pointing to a ground plain.
Now how would I get the light bulbs material to emit light or is their another way to do this?

mm?
If you look around on the forum you will see that there is no material light yet, it might be implemented in the next point beta as in 2.3. Which isnt the one just around the corner.

However you can bake the Light to you materials in your host app,as anyone would do it at this point.

...but cannot make luminous(yet), so of limited value.

Is IES support on the roadmap?
I presume not, because there won't be traditional lights as such.

I dont see that happen, it would be some ugly hybrid for sure.

You need a material that sticks out inverse quare and thats it,fry intensity up or tone it down.
This is what will be done first.

If anyone from Refractive software would care to answer my last posting this would help me.

Thanks,
