Hi,

 

I'm not exactly sure what kind of "lights" you're looking for, but you might try "LightUp" which gives you lights and shadows all from inside SketchUp. You place 'light bulbs' where you want light and/or it will use sunlight.

Best of luck,

Hi and Welcome!

 

I think Sketchup is a great way to cut your teeth into ArchVis!

 

[rant: Wish my kids showed an intererst other than in an electronic game machine]

yes, we use SU on a daily professional bases. it's basically our mainstay modelling facility. you cant go wrong with it.

 

welcome aboard. i see you're exceeding your father's imagery skills already!

so your kids like sketchup

[SandmanNinja]

No, they have no interest in 3D (unfortunately).

 

I tried to get one interested into making his own levels in Unreal Tournament, but he said it was too hard.

 

Not knocking my kids, but I'm just glad to see you have set yourself upon a good path.

 

Listen to your dad.

Eat your vegetables.

You're not wearing THAT to school, mister!

Hi Josh

 

Welcome on board you must be the youngest member here. I don't use SU really but if you turn on your shadows it will seem as if you have light in there. You can turn them on in the View tab it will give a bit of depth to the image which is a good start.

Since you've got LightUp, here's a simple model to experiment with:

Its just a little house with 2 colored lights inside. Unzip, load into Sketchup and press the Tourtool in LightUp and you'll be done.

 

SU view is this:

and lit, its like this:

First of all welcome.

You should go to one of the Sketchup forums. There are a lot of people are really helpfull.

 

http://groups.google.com/group/sketchup or

 

http://www.sketchucation.com/forums/scf/index.php which I prefer.

 

Sketchup works only with sun light sources, so it is not easy to get light into the house.

 

Try following: Play with the sunlight and make your windows more transparent ( or delete your glas )

Do you know you can make your ceilling or roof transparent and from the bottom with a material of your choice? The sun goes through. Same is for walls. Try out to set outside transparent material. You'll see that there is sun inside your rooms.

You can use section cuts to open one side of your house to get light inside.

From scratch: By modeling use groups, create components and work with layers. So it is more easy to hide/unhide unwanted.

 

For other light sources you can try Lightup for Sketchup ( like Adam - electraglide - said ) where you can set easely light points or emitters ( lightfaces ) into your scene, or use something like Podium renderer, which is the easiest renderer for sketchup. ( more complex but for free is Kerkythea renderer ) Renderers are for making realistc images from your model with lights and reflections.

Both are commercials, but have trial versions. Lightup as an 8 hours working time limit and Podium as a full version with resolution size limit.

 

That is the only way to get light into your scene beside sunlight. You'll find both here:

Just a small correction. The LightUp DEMO is a fully functional version with a 30 day limit and just time limits on realtime mode if you want to walk around your model like in a video game.

 

Incidentally, having been in the games industry for 20 years (my first game was published in 1983 by Atari as a wide-eyed 17 year old! ) , LightUp uses a lot of video game tech. The IrrCache is very similar to the techniques used by HalfLife2 in their Source engine.

Hi Kiddo

 

Are you also using vray in sketchup?

In that case you can make the model just like you want, and you can place 3 kinds of lights:

1) draw an object, and give it a vraylightmtl.

2) place a vray rectangle light (right click on it for properties, all the way down)

3) turn on shadows, and in your vray settings, in the environment rollout, make sure both GI and background have a map (large M, if you double click, you should see a dialogbox, with a skymap selected)

The date settings in the sketchup shadows dialog will influence the position of your daylight.

 

good luck!

ok i got the light in it look good but in side the house it is dark and the garage

is towhat do i do about it

[RayOfLight]

The reason why it's dark, is because your camera is set for sunlight by default. Take a look in your camera rollout, you'll see ISO, shutterspeed and aperture (f-number). Those three settings tell you how bright your endresult will be.

For a brighter image, turn up ISO, and/or turn the shutterspeed down.

(shutterspeed is 1 devided by the given value, therefor a smaller number, will result in a longer time, 1/100 is less then 1/30)

 

The problem with this is, you can get your interior light enough, but the exterior will be overbright. Make sure you turn on sRGB in the VrayFrameBuffer (at the bottom, about in the middle there is a small button). If this all doesn't help enough, you can only make the lights inside the house brighter.

 

goodluck!
