I have this sign box and I want to achieve the same effect as in the 2D drawing. There is a LED strip that spans from the top to the bottom of the triangle on the left and left to right on the top. The red line indicates where the LED strip will sit on the top elevation. I want to have a nice gradient glow on both pieces how do I do this? Create a geometric cube, hide it from camera and apply a certain emissive value?
Not sure if this post would help at all. Seems to create a very similar effect as you're looking for.

man, I wish I had Keyshot when I was working in the sign industry. Probably would've sold more signs with this than the plain flat 2D drawings that look like everyone else. Good luck!
With the use of Keyshot, it has given our clients more bang for their buck. They are just in awe when they see their sign concepts fleshed out into 3D virtual models. Then to be able to use Keyshot XR to move it around and inspect it they just get giddy.
