Only took me a few seconds to find a bug, just grab a surface light, and set the angle to 180. The guidelines will disappear.
It seems while doing this, the width of the guidelines becomes slowly infinite towards 180 degrees.
If you want to see the bug in almost full form, set the range to 1 and the angle to 179.
Here is an example:
Nice update, I’ve always had problems visualising the range of the lights, usually I’d have to turn it to night all the time. Thank you!
Bug: the light guides don’t disappear when you move the lights.
I haven’t selected anything. It’s quite annoying.
When you move it from a parent like the workspace.
Uh oh, that isn’t expected behavior. I thought I’d accounted for this case, but I’ll take a look and hopefully get in a fix by next week. Could you elaborate on the exact steps you took to cause this issue? I’m having some problems reproducing it on my end.
Please refer to the following reply: Light Guides - Visual Assists for Light Projection - #20 by YodelerYoshi
TLDR: A fix for this issue is coming next week
Now this is an update I could really use!! I’ve been struggling a lot with lighting, specifically those pesky spotlights; I feel that it’ll be much easier now
Sorry about that. I meant to say folder not workspace.
It’s actually pretty simple.
Create a Folder anywhere
Make any light inside inside the Folder
Make a part or attachment somewhere in workspace
Move the LightObject into the part or attachment
Deselect parts and attachments
What is even stranger is that it stays on even after I delete the LightObjects and the Part and attachments too. https://gyazo.com/e37a32844de3248bbfcd0bab92640282
Edit: This also seems to happen whenever the light is created in somewhere or when I load a new place too.
Such an amazing update for Developers who use lighting in their games.
This update will make lighting easier and faster.
Thank you for being so thorough in your response, this helped a lot! The fix should be in next week.
This is super cool! Will we get image/decal projectors too some day? Not entirely sure if that’s similar to light projection but I see it as a possibility?
Anyways, this will be super useful for fine-tuning light in maps and such, lighting is surprisingly important in a good-looking game so I’m definitely a fan of this update.
It literally looks amazing, can’t wait to use it in the near future projects.
Nice job!
This is really useful, I love it
This is a very needed feature to builders and even who use lights a lot!
Amazing update! Good job!
Pretty useful feature, thank you Roblox! Finally I won’t have to sit there, feeling silly and rotating through the directional properties trying to work out what side of a part my light object is actually coming out of.
Wow! I might be able to make my work easier with this! Thanks!
I didn’t know i wanted this.
Next: unlimited light range? please
Y’all should make guides like these for proximity prompts too! Would make the workflow of using proximity prompts a lot more convenient.
Awesome addition, no more need for light plugins!
Allows you to create lighting effects way faster! good idea. 
Awesome. This is something I’ve been wanting for quite some time. Light guides are a staple of modern game engines, so I’m glad to see it finally added. The studio team has been on fire these past few months, keep it up.
