Iray and default lighting [Solved]

j_koko2_f2572d4e05

Hi!

Just started playing with 4.8 beta and Iray.

Having an issue where I have no lights in the scene and I am still seeing light on the model.

I have turned environment to Scene only. Deleted all the meshlights I created, however I'm still seeing light.

Where is it coming from? :)

It's driving me nuts!

SY had a good vid to get you started. Tho I did discover that the heard way myself.

Omni Uber Aria lights do nothing at all in Iray, There is an "Iray Emissive shader" you can apply to them, tho the Emissive shader dose not work in 3delight, lol.

Photometric lights do work in both tho.

Ivy, in the render tab, did you dial "Crush Blacks" back to 0.0 from the default of 0.2?

"Tone Mapping" intro for Iray (what is ISO### for, etc). In the "Tips & Tricks for Iray for newbies" thread.

I Think we all are just starting out, so what you ask for, a "Basic guide", may not be ready. This is Beta after all. There are a few threads on Iray, SickleYield has a vid and a few tutorials (the last time I looked).

Lights note that I can't find;
Lights that only have "Lumen" controls are for Iray only. (And don't work in 3delight).
Lights that only have "Intensity" control are for 3delight (And don't work in Iray).
Lights that have both (Photometric Lights)... "Lumen" control is for Iray, and the "Intensity" control is for 3delight.
So just remember - "Lumen" control is for Iray, and the "Intensity" control is for 3delight.

Not much sleep, need coffee.

Thank you very much for the info.
I seen SickleYields thread but its not much use for a quick users guide when your looking for a specific setting
I wanted to learn everything i could about using the light in Iray before I attempt to learn about the shaders, I am kind of surprise there was not a quick user guide.

The thread isn't a starter guide, this is:

There's one about shaders, too:

Thanks, but I had already set up mesh lights using a plane and the emission settings in Iray Uber Shader. I wasn't using anything 3delight compatible.

It wasn't the issue.

I did, however, find the settings for the Headlamp in the camera which was causing the extra light :)

Once I turned headlamp off, my regular meshlights worked!
