Hello Face.
I'm wondering, if its possible to setup orientation of IES emission source by softimage Spot light.
Do You think its possible to calculate IES orientation in octane by orientation of softimage light ?
Maybe IES profile export would be possible too...

The obj-format doesn´t support IES profiles.
The next plugin version will have a support to export area lights as geometry.
Then you can plug an IES profil in Octane on it.

Ok, but problem is with orientation of this IES profile. Even if you implement area light, which is very cool by the way.When i was playing with IES lights I've notice that plane rotation doesn't rotate IES. Orientation parameter is difficult to manage in octane . You simply have no idea where "center" of light distribution cone is pointing. Try to make 10 different lights with 3 IES profiles and try to operate them. I hope you understand what I mean.

Face, If I understand it right I can use IES Lights with Area light from softimage since I import IES profile in octane.
That´s right? Or I don´t understand?
Regards,

Correct, the plugin exports the arealight as geometry and you must only setup the lights and add an IES profile in Octane.
The best choice is to select the sphere as area geometry for IES.
If you have multiple the same ligths add an diffuse node in Octane and put it in every light slot.
