Rendering a dark scene in Blender 2.8 Cycles + glass shader with lettering After putting way too many hours into this scene, I'm finally ready to render. The problem is I get a ton of noise, no matter how many samples I choose, and denoising just makes the image look like garbage. I've searched and searched and searched for a good solution, but I can't seem to get it right. The image attached was rendered with 512 samples without denoising and took about 45 minutes. Please somebody help! Also, if someone has a better way to set up a glass shader with lettering on it that will allow light to pass through the glass and not the lettering (see the signage on the desk for example, the lettering should cast a shadow), I would be greatly appreciative!

[EDIT]: Added an updated render and a screenshot of my settings
[EDIT2]: I'm only seeing the updated render, but none of my other pictures are showing up for me. I hope you all can see them.
I increased my render output resolution to 4K and got rid of about half the amount of light sources and nearly all the noise disappeared! Also, I managed to solve my glass shader issue with a few extra hours playing with the shader editor and came up with a great solution for casting the shadows I was looking for. I've attached a screenshot of the shader node tree, I hope someone else can make some use of it as well.
