Having trouble with my ceiling lights not fully rendering. The file has now process 255 passes and the ceiling lights look very spotty. I am using the ceiling lights to uplight a wall from the bottom in an even glow (no scalloping). I have now turned up the lights per pass to 100% and min. 100 lights per pass, but it is not doing anything different

I rendered the model that you sent Al, and it rendered OK for me. I have uploaded the rendered image after 80 passes, but it looked good after just a few passes.
I also stripped everything out except the component with the single light in it, and the floor, and rendered that. It renders OK too.
We'd like you to try the smaller stripped model to see if you get different results.
Can I just upload the stripped model here? Or would you rather I sent it to you directly?
Rich,
When you turn down the brightness of the rendering can you see any spottiness? The renderings of the single light that I posted above looked similar to yours prior to reducing brightness. Can you post the .nxt files or your rendering?
I placed the image in line in this post using the camera/image icon, and telling it to show a 600 pixel version. This work better than an attachment - since we can see the image directly in the post.
Check the number of lights that we are extracting from SketchUp. (Sometimes it is not the number of lights you thought you had in the model)
In the rendering window, click on the top of the window and choose "Statistics" this gives us a count of the lights in the rendering.
There are some possible problems where we may create too many lights out of a SketchUp surface. We try to add all the faces in a component or surface to a single light, but sometimes we have a problem when the individual triangles are not contiguous in the surface and we create way too many lights.
Also, try turning off some (or all but one) of the lights and render it with one light at a time to see which lights are working as expected. This can be done easily by placing lights in a layer, and turning off that layer.
Al,
here is the image..
It rendered for 65 hours over the weekend. 255 passes @ 33%/6 min lights per pass and 6 passes at 100%/100 min. lights per pass. there are 9 spot lights and 3 point lights plus a point light in each of the hanging spheres above the desk. The 7 ceiling lights are 50mm wide and varying lengths

A Linear Light (bottom) with 8 sub-divisions, compared to a rectangular light (top) after 20 passes.

I had a hard time locating the ceiling light. (we need to add an easy way to highlight lights in SketchUp)
is the ceiling light in the ceiling?
we do have a couple of ways to turn any surface into a light, if that type of light would be better for this model.
I did try to turn the face (the face being uplit) into a light source but ran across the same spotting issue with the light hitting the floor surface.

I wold be interested to see a rendering with:
1. Just one ceiling light
2. Just the ceiling lights
3. Just one set of 7 spheres above the desk.
