How do you actually assign lights to passes?
Material pick the light, open the Emission pin, and set the Light Pass Id to whichever pass you want (ie. 1-8). Then turn that pass on in the Render Passes node.

Great thanks, will give that a try later on

Hi Paul, I need to make a gradient texture - it's a glass wall that has an opaque gradient coating on it. So the bottom of the wall is opaque white and get's clearer towards the ceiling. How would I do this?
Thanks

I think the easiest way to do this a make a map in Photoshop or GIMP, with black at the bottom smoothly changing to white at the top. The assign that map to the glass material in the opacity (or roughness?) pin.

Seems like using a gradient for opacity is working. Thanks!

Hello again
I've just rendered out another image with linear lights that all seem to be fairly aliased
Any idea on how I could make them smoother?
Thanks

Sonneman,
Hard to fully understand the issue without an image but the following might help:
a. Too low an image resolution?
b. Even with high resolutions I always add a slight bit of bloom to soften the edges as it would in real-world photography.

As Seeker indicated - can you pls post a sample render.

Sure thing:
(the colour choice on the seating was not mine)
If you look at the linear lights in the recessed ceiling areas you can see the aliasing.
Thanks

Impressive scene. The lighting is great!
If you look at the linear lights in the recessed ceiling areas you can see the aliasing.
I believe that the solution for this is to 1) increase the Kernel->Filter Size - my guess is somewhere between 2 and 3, and if that drops the clarity of the rest of the render, double the resolution and downscale it in Photoshop. The Archiviz experts here might have some better settings. If you post your render in the WIP Gallery here, I'm sure others will comment.
