Line Light Rendering

Recommended Posts

Hello, would anyone be able to help me understand why my line lights won't all render? I'm using realistic interior renderworks, i have 8 line lights that need to render and other light sources in the space, but when i create a viewport and render only a couple of the lines show?

I'm trying to create a glow behind the object in the centre (see attached image) so the pattern is illuminated. The pattern is cut out of the solid, theres holes for the light to shine through, and the pattern stretches the length of the line lights (just hard to see in open gl) I've tried every different falloff light mode, the smooth setting produces no light at all, and the realistic works well but only certain lines render. I turned off ambient occlusion and renderworks backgrounds in case indirect lighting was impacting it but it didn't make a difference so not sure what i'm doing wrong! also i have the line lights set on 10,000 lumens for brightness could this be why?

I've attached images to indicate what I'm trying to do, any responses are really appreciated!


ps. I'm an interior architecture student doing my final year projects so if i've missed something obvious sorry i've not been using it that long! 🙂

Hello Holly:


Can you attach a (simplified if you want to keep your model private) file with just like a line light up against the wall in a viewport that shows this?

I can attach the model file if that helps?! it takes a couple of hours to do a realistic render of the lights and then some don't show so couldn't get a render to show the issues

Sometimes I have to pump my line lights up to an outrageous output for them to read.  Stupid question, but your "lights" class is on in the sheet layer you're rendering in, right?


When you reply you should get a box at the bottom of the window where you can drag files to upload them

oh right I thought 10,000 was pretty high already! and yes thanks for the reply and the suggestion but the class is definitely on!

I tried dragging the file in a few times and deleted a load of stuff out of it to make it smaller but the upload still failed, i keep getting this error message
