Fix Your LUMION LIGHTING With This Trick!

- Опубликовано: 17 авг 2024
- The biggest issue I see with Lumion artists renders that ask for my advice, is the lighting nodes are far too high for interior scenes. Most of the time their renders look far better just by tweaking light values. The default value of 300 is absolutely INSANE. I typically use 1-25 depending on the location of the light, with even 100 being very high.
If the value of your lights is too high, you have to compensate with effects but that can lead to losing detail.
The first comparison I did was just to show how the lighting changes, but I realized that where it lined up with the video was kind of confusing. The value in my comparison was 20, where the viewport would have been at 7 during that time.

Finally a video that explains it!! I've had trouble for years with the right lamp, which have shadows... Light coming through walls and the luminance values, Thank you!
They should just connect values to lumens, it would make whole process easier, and also enable rendering accurate lighting scenarios
I agree, there needs to be some kind of update to the way the values are displayed since it really doesn't make sense. The slider is not linear and I think that really messes with people.
Thanks for checking out the video!
This was so helpful man. I have been struggling with the lighting because of this fact and now i understand that they just put some random number as default. and here i was thinking the figure was actual "Lumen" value, I'm a lighting expert but putting it to lumion the program it just didnt make sense. 400 lumens is so low but Lumion "400" it just looks stupidly unnatural.
So so so helpful, this really is fundamental lol they should feature this for people starting?? Obviously lack of raytracing limits interiors but I think sooooo many people (myself included) have trouble with interiors purely because they don’t understand these settings. Took me a while to notice how insane the values on the lights are because the slider bar makes it look like they’re relatively low
Exactly! To me it seems like as long as the light source is strong enough to reach the floor that is around where it should be. I do hope they make an “exterior” and “interior” section just so people who are new will have different starting values.
I don’t completely understand how the values work myself, because it doesn’t seem to be linear. The ies profiles that are built in seem to be quite visible even at the lower values
I’m glad this video could help you out!
I always feel like I am turning knobs blindly when it comes to lighting, like Area Light vs Lime Light, vs spot lights, I get lost. And, Yeah, with a default of 300 I always think I'm doing something wrong when I crank it down to 45 in order to get it looking "ok". Thanks for sharing your knowledge.
This is just what ive been looking for! Thank you for this!!
THIS IS AMAZING! thank you so much, LL!
:)
THANKS FOR THE VIDEO, YOUR VIDEO OPENED MY MIND! I APPRECIATE THAT
THANK YOU SO MUCH
I really hope they add the ability to dial in the brightness before placing lights in the scene. Right now you have to add a light, change the brightness then copy that light around. Thanks for the great vid.
You can add multiple lights first, then adjust the settings of all similar lights at the same time. I am Not at a computer to explain the exact steps, but it is super easy once you know how.
You are correct, however I think Lumion needs to change this. I am confused why it is not possible to link lights. If you have 6 lights in a living room they are 99.99%+ going to all be the exact same light so why can't they just mimic each other.
Thanks a lot for checking it out! I hope it helps :)
Hey Greg, nice vid :) Glad you mentioned D5 at the end.. I was going to ask you about that! Looks like it has a lot of potential- esp interiors compared to Lumion. Look forward to seeing your vids on that 👍
Hi Geoff!
I have been playing around with D5. While it is not as polished as some people would have you believe, I think it is better for interiors than Lumion. There are a lot of things that I find can make Lumion turn into a dumpster fire with interiors that D5 has no problem with.
Overall it seems like a much much faster render as well, but not as many output settings. If you have not heard of Nvidia DLSS I would recommend looking briefly into it. DLSS is a huge feature that is going to be the future of rendering.
@@LuminousLabs Thanks Greg! Have just been looking into DLSS, thanks for the heads up. It does sound interesting. I still haven't found the time to experiment with D5 as yet.. I realise it's still being developed but it does look like it's going to give Lumion a run for it's money esp as it continues to add new features. I'm also hoping D5 is fairly easy to learn.. I'll definitely be watching your D5 vids to hear your thoughts.
@@geoff2579
I actually think D5 is far easier to learn, a lot of the learning curve from lumion is just built into D5.
I recommend everyone give it a try, it's never bad to have options!
Thanks for the video! I always found lighting in Lumion very messy. Also I wonder why the presets in Lumion scenes are so bad!
That's why my night scenes look so unnatural! but just want to ask, during your example i noticed that the ceiling was pitch black. do you have to make an opposite spot light from the floor to the ceiling so the object can be shown as well? Thanks again.
Loved it thanks for sharing
Please bro , how to fix the problem of the spot light when its light leaked from the walls ?!
Thanks very nice
great tutorial 👍
Could you do a realistic lighting timelapse of a full scene with rendering settings?
Yes I can! Actually I planned on doing that with a scene I got featured on the Lumion website I kind of forgot about it.
I will put the link in here when I get a chance to film it!
@@LuminousLabs thanks a lot man. Cant wait for that. The sooner the better. 😊
Also it would be great if you touched the topic on how to work on layers to make day and night lighting in same file
great content. You have a new follower
I'm extremely happy to hear that! I am looking forward to seeing you in the comments of future videos!
Why my some objects looks fake after the final render ?
Thank you for your video, another thing that could be included in this video was gi effect, i learned it in desir school channel,and that effect make shadows and artificial lights much better
I actually don't like the GI effect. Hyperlight is actually the new GI effect, but for some reason Lumion wanted to keep the old one in for people who were used to it. The GI effect doesn't deliver the same results as Hyperlight but is WAY more expensive. Hyperlight should have been called GI2.
Thanks for checking out the video I hope it helps :)
@@LuminousLabs hi, thank you
i will check it again,and compare gi and hyper light but im still thinking، when you apply gi and select ies lights, you will get much better lights and shadows
For a daylight scene in lumion, go to the skylight tab, turn first dial to 85, second dial to 20
Do you like to use the Real Skies? That is normally what we use for lighting.
Thankyou for lumion lighting tutorial.
Why lumion lights intersect surfaces ? How can we avoid this?
What I assume is happening is you have an area light or a fill light. These lights don't cast shadows so they will just pass though the geometry unfortunately.
If you are using fill lights at all, swap it to an omnilight and make sure it is casting shadow.
Thank you, you still help us a lot. I have a question. If you use a small percentage of lighting, usually the ceiling of the room is black and it does not appear what is the solution to that
Make sure you turn on hyperlight preview. It might actually be reaching there when you hit the render button but in the preview it just comes up as black.
Let me know if this was not your issue and I can again!
Thank you!
You're welcome!
Hmm good job researching this actual sphere of influence for a light point. I knwe thatdefault 300 units is way to strong but didn't figure out the light kind of "cuts" after reaching the distance as shown here. I wonder now how much difference would it make to select the lights at small values and make them work with global illumination
I haven’t played with global illumination effect but hyperlight does seem to work a bit better! At the very end where I turn the lamp up, you can see how much more noise it brings in the scene.
The sphere of influence is called its attenuation, I just wasnt sure if everyone would know what I meant since that word isn’t anywhere in lumion’s interface.
Thank you for checking out the video! I hope it helps you out :)
@@LuminousLabs I think (and hope) we're going to see a major improvement in interior lighting in the next version - it looks to me so from what Lumion devs have shown in the teaser. As for hyperlight - this has always looked kind of random to me, not really a realistic effect, it mimics the color bleeding effect which ray tracing would give. reason why I thought of GI instead was in relation to what you have shown with this sphere of range that a single light point has - perhaps marking a light to work in GI effect could help that?
Nice one.
Thank you! Cheers! :D
What do you recommend on pool lightS?
There is a not an easy solution to that unfortunately. The best advice I would give is to tweak with a narrow spotlight and then put volumetric lights on it (if you have Lumion 12).
cheers
Cheers to you as well my friend!
Wow
I hope it helps you out :)
Still bad
