Yes, the .RBZ files are not SketchUp model files. They are SketchUp Extension files.

Launch SketchUp, open the Extension Manager, click on "Install Extension.." and choose the .rbz file you downloaded.

Thank you for the information! very good article!

Good evening Adam
We bought a few months ago a Lightup 5.3 annual license.
Today we had the need to reinstall the extension, but we could not , because the registration code that we used is not valid. You can re-enable our code?
We should have the for free up grade to 5.4 , shouldn't?
Could you kindly tell me the procedure to do that?

best regards

hey that looks really cool brosky.

Hello Adam,

I have uninstalled the demo version long ago. Never got it to work right or my PC needs an upgrade. Meanwhile I need my Sketchup, and every time I start it though, I get the Lightup Demo Registration window. Please please, it's killing me! I even tried to uncheck the extension and it still pops up!


andrea I.'s picture

dear Adam

i bought light up and i very entusiastic. But i found a bug for mirror/specular materials

for example:

In the same file i have 4 surface with the same material

2 surface mirror correctly
2 surfece doesnt mirror correctly


I finally figured out how to unintall the program:
You can find the .rb file in AppData folder (usually hidden) under Users folder

LightUp is a lovely program. Its just a personal taste that I prefer another rendering.

Best lucks with LightUp

Hi Adam,

Would you please let me know how to UNINSTALL LightUp for SketchUp( the Trial Version)!!!

I have been trying everything and nothing worked...


Adam B.'s picture

Easiest way is to open Preferences->Extensions, and uncheck "LightUp Tools".

สวัสดีครับ ขอบคุณครับ

good afternoon,

i was wondering why it is taking me too long to render a scene with a lot of faces. it says __% complete (2___.__ Mrays)


Adam B.'s picture

Hi Louise

The time it takes to light a model is largely effected by Resolution you have set in Preferences. For an interior, start with 25cm to get a quick result and then drop down to 5cm for final output.

Please watch this video on setting Resolution: https://www.youtube.com/watch?v=ywyI0vJNNzQ

At first I was delighted with the overall idea of lightup and bought its perpetual licence. Now I can easily say that it may be the most unstable sketchup renderer plug in. It's very difficult to take the same effect everytime, there are not much customization options and its user interface is waaayyy to old an difficult.

Also the author of the plugin tried to charge me another perpetual licence price to upgrade my version. When I told him that perpetual means perpetual like all the other programs he told me that "it's only perpetual for the version when you bought it, if you want to go perpetual with the next version you have to pay again"

Now :) this isn't funny. When I resisted, he accepted to upgrade for one time (still appreciate it) but for the next version I won't be "perpetual" anymore he said :) Sorry to hear that.

Anyways, I don't need it anymore. My advice to all designers who search for a quality sketchup renderer, just search a little more. I don't want to give the renderer name I'm using now but you will easily find it which has much more quality end results, have a much more modern and easy user interface and is real "perpetual".

Totally, good at first, not satisfied when you get used to it and see the other competitors.

Hi Adam,

LightUp is truly an amazing software!

I've got an entry level PC and LightUp still works. After removing most of the planar reflections, questionable components downloaded from 3D warehouse, Pointlights that were way too strong, Sketchup surfaces that were not quite planes and grouping building and grounds into one group, I could then set the scenes and actually made a movie out of it. I had to render in LightUp twice because the rendering didn't complete the first time (presence of dark smudges in some areas). I used Sony Movie Studio to compile several movies together.

The finished movie looks really good. The camera movements were smooth and graceful.

Thank you for your continuous support. It's a great product.

I am going to get a new computer with a faster processor and better video card. Could you show me how to load LightUp to the new computer? Do I need to use the key for the last download?

Hi Adam,
I noticed whenever a Sketchup model is in LightUp rendered mode, the camera movements become jerky and sluggish.

Normally the camera in Sketchup moves very smoothly.
We are not dealing with animation or movie recording.

I just want to show the model in LightUp rendered mode to clients but it has proved unsatisfactory.

Is there anything I can do to make the camera move smoothly on screen in LightUp?

pokongku .'s picture

I managed to record this segment, not using the LightUp recording feature, but by OBS Studio video capture and then editing it in Sony Movie Studio. https://www.dropbox.com/s/f94hcm1r9w63cyh/SCENE11ex2.mp4?dl=0

I could not get LightUp Movie Maker to work. Kept getting the bug splat.

OBS can record in resolution of 1920x1080 and higher. How do I set up LightUp for higher resolution rendering?

Also when I use the camera motion control in LightUp rendering, the action is not smooth, as you can see in the attached segment. Anything I could do to improve on that ?

Hi Adam

I purchased the annual mac lightup for sketchup lisence few days ago, but the file was not downloaded successfully for unknown reason. Today I checked my online bank and realised the lisence actually costs me 148 pounds !!!

If there is nothing wrong with my memory, the price I paid is different with the price I saw previously on the website. (I thought it's 14pounds or sth. The payment page pop up when I was in download page, and there was no option of visions , the one I got is not even a student vision) I paid this much for a plugin which cannot be used in my laptop, so I am asking for a refund and sorry for the inconvenience.
I am a interior design student so I would like to download a 30 days free trial and if I like it I will recommend it to my classmates and get a lisence later , as a student I really can not afford the price of the annual lisence right now so please help me and process a fully refund to me plz!!!!!!!!

Hi Ruby L.

If you are a student you should maybe consider the "Thea for SketchUp Academic License" (39,00 €, June 2016). I think it is reasonably priced and it works for both Mac or Windows. All Thea Render licenses, including academic, are perpetual (non expiring) and contain all features. I tried the Light Up trial, but it was not suited for my needs.


Adam B.'s picture

I think you are confusing 2 different technologies. If you want to start a render, wait 5-10 minutes and get a single Still image, use a *raytracer* like Thea.

Now LightUp is a *realtime* lighting engine that allows you to navigate around your lit model under your control. Creating Still images at very high resolutions is almost instant and Movies take a fraction of the time of a raytracer.

Unfortunately, the term 'realtime' is often misused - its correct meaning is being able to display *finished* rendered images 30 times (or more) per second. Raytracers like Thea are fine products but are not realtime.

Do I need to un-install LightUp before downloading new installer for new version of LightUp with existing Reg Key?

Can you please respond to the issue of LightUp not being able to animate the scenes?

pokongku .'s picture

Hi Adam,

As per your instructions, I have "hidden" all the PointLights, leaving just a minimum of emitters. The building and grounds are in one group. I am using AO and have set the color box to black and custom AO at 6m. Resolution is 5cm. I planned to add pointlights back one at a time. Gamma as been set to medium.

Now every time the model was rendered, the program would crash at various points, although the rendering time is shorter now (about 3 hours). Bug Splat reporting followed. Ruby console is empty.

I have not changed anything else. I use to be able to finished rendering the files with no problem. Could you please help by reviewing the attached file and see if it would render at your end? Here is the dropbox link : https://www.dropbox.com/s/4c3aqqdgcz8mhmm/BUNGALOW%20MAY%204%201AM%20in%...

Hi Adam,

Still struggling to make this thing work. I've turned off all planar reflection and turned on Trigger Anim.

1. The animation still does not work. It is frozen in the opening scene. I tried the animation in SketchUp mode and it worked.

2. None of the point light or emitter worked as if they have all been turned off.

I have sent you the SU file hoping that you will find what I have done wrong.

LU crashed after getting stuck in animation. (SU Bug Splat notice popped up.)

I've recently purchased the LightUp full version and am still experimenting with it. I find it very difficult to control the camera movements, with the mouse or the keyboard. There is no "braking" and the camera always ends up in the middle of a wall and causes the screen to turn black. And sometimes during camera movement, the screen froze so the program could pause and catch up (with status bar turning).
I made a small movie of a very simple model and it worked well.
Now I was trying to make a 12 second movie of a larger LightUp model (160Mb) and no matter what I did, the outcome was just the fixed image of the opening shot. I cranked up the camera speed to 5 so the camera could move without stopping. I had Trigger Anim on all the time. I tried different resolutions from the lowest to the highest - nothing worked.
I sent the whole SketchUp file to LightUp hoping to get some clue of what to do next - so far there's been no reply.

Adam B.'s picture

When exporting a movie from LightUp, if you have "Trigger Anim" checked, LightUp will autoplay the Camera animation setup between Scenes. You need at least 2 Scenes setup in order for LightUp to animate between Scenes. Having just a single Scene setup (as in this case) means LightUp will wait for you to manually navigate your model and record your path.


Hi Adam
following the tutorial on how to rig up an interior when i get to the stage of selecting the tour tool for incremental render sketch up closes and i have to restart it?

hi Adam,

wondering why my student version keeps crashing whenever I try to render my model. First time using the student annual version, i used the demo version before this and it rendered fine.

thanks in advance,

Adam B.'s picture

Hi Louise,

Yes, we had a couple of crash bugs in the last release. These have been resolved and if you login, go to Downloads and at the bottom of the page enter your RegKey, you can re-download a new Installer (5.0h) with the fixes.


hey there, i clicked get this extension, then signed up for the 30 day trial. however when i downloaded the file, it launched sketchup, then when i clicked start using sketchup, sketchup loaded then gave me the error message " this does not appear to be a sketchup model" this is very frustrating as my normaly sketchup loads just fine but this only happens when i click the lightup download rbz file. any help appreciated.

Adam B.'s picture

Hi Hugh,

LightUp downloads as SketchUp ".rbz" file. Its not a SketchUp model (.skp file).

- Simply launch SketchUp,
- Go to Preferences->Extensions,
- Click on the "Install Extension.." button and select the ".rbz" file you downloaded.


kendrick A.'s picture

when i open my install extension i can't find my ".rbz" file? where can i locate it?

Adam B.'s picture

In your Downloads folder.

Adam has been using SketchUp since version 4 when he was working in the video games biz at Criterion. LightUp grew out of the desire to marry video game realtime graphics with the great usability of SketchUp.
