Great. Didn't know it was possible. Thank you, I will try.

Select the lights shape node and in the extra attr. section change the global to movable proxy. You can now move the lights and the IPR will update. This is also the case when you want to interactively move objects as well

Mesh converted from liquids such as realflow or maya bifrost get it, other than that I couldn't find any info either.

I use black flags (simple plane) just like the real world photography.

Render Layers with light/object ID's can also bu used but requires Layer matte and compositing.

Ok I have tried to come up with pure BW solution. I have setup a simple scene with 2 objects. Assigned second object with Layer ID 2 . Enabled render layers. Rendered Layer 1 with Layer Mask pass. And the result is pure BW.

Here is the scene

Every Maya Camera have all the octane settings automatically. I have never used Octane Camera, In fact I have realized there is an Octane Camera button after reading your question .

Some software can not handle multi channel EXR file

New plug-in defaults to composite exr file. Try disabling "Save composite EXR file" in the render settings.

Hello,

Example: I try to render a car model which I have bought. I use a simple specular shader for the windshield, nothing fancy.

Since the model has ...
