lights question
I have a question about using the lights in SH3D 3.0:
When I render the scene (using the Best or next to Best setting) There is now a huge light/white spot on the ceiling. I used the Halogen light (the same light that was used for the beta tests) and have it set to 25% power. I hadn't noticed the spot on the ceiling caused by the light before. Is that a new problem? I'll have to play around with the other lights to see if that still happens.

I'll attach a rendered pic to show you.

Re: lights question
Wouldn't you have forgotten to unselect Add ceiling lights check box?

Re: lights question
That was unchecked already. I can attach a screenshot of that if you like.

Re: lights question
pencilart,

Indeed, lights tend to show bright white spots on ceilings, especially if the light is placed closed to the ceiling. There are a few things you can do:
- place the light lower, obviously;
- make the light larger, so that it seems softer;
- make your ceiling (and walls) Matte so that the bright spot is not, or less, visible.

Re: lights question
ok, I'll try those things. Thanks!

Edit:
the light is now 4 feet 6 inches (I guess that means from the floor?)
the ceiling was already set to matt
the light is now huge, lol, but it does now look softer.

I have the same problem and I surely don't have unselect this check box... 'cause I didn't find it. Could you please tell me where it is?

Re: lights question
Cactus,

I suggest your first read the user's guide and the help files on how to work with lights.

Then ask your question in such a way that you don't force us to read the entire thread to figure out what you exactly want to know.

Re: lights question
I exactly wanted to know where is the "Add ceiling lights" check box. I finally found it, it was simply in the "create a photo" box.

Thanks for your help.

Re: lights question
hi ppl, this software is awesome, i really thank and send appreciates to developers, after 2 full days working on user guide and samples i could succesfully create a room scene, i tried lots but just couldnt make sum so i m asking to masters, one of walls just dont change the color, other one (on right) is close to white but the one which is trouble(one left) just dont change color, i tried to add texture by a white wallpaper but it just didnt take the effect again, its always grey, isnt there a way to get together all walls or selected ones to behave together like elevating and CHANGÄ°NG COLOR , wall just dont change the color, may u help,also the frame and curtain have white pixels around, i just couldnt solve that problem after many tries by lights, do u have any advice for that too??
i m making arrangements with ceiling lights!! may u tell me what basicly ceiling lights add? cus in the sample pic below ceiling lights added and one more white are next of white spot(at top of pic,and i know its cus of in the air-area light that pencilart used in his scene),i dunno where it came from..

here is my sample

Re: lights question
Are you sure you changed the right side of the wall?
Do you the color or texture change in the 3D view ?

Re: lights question
i tried color change at first and then tried texture change texture(by a white sample pic), for sure i try changing both sides to check it , i didnt get what u mean by 'in 3d view' ? i make changes after clicking the object on upper side of software(2d mode screen) any settings can be maked by right clickin on 3d view screen?? i dont see any settings about walls or objects, just sum light and transparecy settings in modify selection!!

Re: lights question
The 3D view is explained in the help and the user's guide.
An other idea : maybe you created two walls at the same place. Select the one you want to change, delete it and check if an other wall is still there.

Re: lights question
in 3d view screen there is no edit about walls, just light and brightness, i edit colors of wallas on 2d screen , right click on wall and modify walls!! aint that right, i choose white , it shows every color but not pure white, just a grey tone at last point

Posted by Puybaret at Mar 19, 2011, 7:49:21 PM

Re: lights question
There's no wall edit in the 3D view, but it's there where you can see the effect of changing wall color or texture.
You'll never get pure white unless you increase light power. If everything was pure white you wouldn't distinguish shapes.

Re: lights question
I think there's a misunderstanding about what you expect to appear in the 3D view. This image was computed with photo creation dialog at one of two best quality levels.
Please, please, read Sweet Home 3D user's guide from the beginning to the end. It's not so long, and you'll learn many basic features that will help you to better understand how Sweet Home 3D works.

Re: lights question
no,no,:D:D after arrangements of lighting of lambs, and ceiling lights NOT clicked, i m creating best result high quality of image of 3d view screen, of course 3d view is just screen, i m takin a high quality photo by advenced rendering photo plug in, i ve learned that from begining, just wallas dont change lighter than a matt grey!

Re: lights question
I tried using the Advanced Photo renderer with different wall colors: 2 are beige and one is blue. As you can see, the colors are very soft, you can hardly tell that the 2 beige walls have color.
My settings:
North is at 60, the time is about 1:20pm, Silk walls, ceiling, and floors is set to "off" but I did use the Silk rendering setting with ceiling, lamp, and sun checked off (meaning the box is checked). The power for the wall lights is set to 40%

Re: lights question
Nice layout!

Just for experiment, change the wall color to a dark blue or red and see what that does. As you've seen with my rendering, the beige walls came out very pale, almost white, and the beige shade that I had chosen was much darker.

Did you try the built in renderer? (the one with the black camera icon from the menu bar) Just wondering if that would give a nicer result. I've noticed that it renders things a bit differently.

Re: lights question
Soul,

if you share your SH3D file, I will have a look at it, and see why you can't get the colours you want.
