Can anyone please tell me how to use Object-Id Render Element then?

It looks the same as Material ID.

I can use RenderMask from Scriptspot and switch to Scanline Render.
But it's not working when I want to render trees with opacity maps from Octane.

Btw. It's urgent

I can do it manually by assigning a black diffuse material to everything except the trees.
Then give the trees an emmitting material with surface brigthness checked and illumination unchecked. I need to copy opacity maps from the leave materials.
Then render with Direct Light and no GI.

Takes forever...
