Great Program... Many thanks! .....but there are a few questions..
I am a very old school CAD user. I work alot with industrial apps and DWG but I love working with architectural drafting. I downloaded your program to get more familar with plans, and layouts, and I am just now learning about 3D graphics. I'm an old dog, and need to learn new tricks. My problem is the built in render with SH3D makes my photos I create very blurry, and dark. I tried using the light bulbs, and downloaded the Ubershader, but I still can not get the render to a good quality.

I have read somewhat about the SunFlow renderer, but I have no clue on how to get scenes from one program to another. And I have very little programming experience, seeing I learned most of the language back when DOS was still a stand alone programing language.... biggrin So I not sure if my problem is my graphics card, or the renderer, or my memory.

Sorry if this seemed a disjointed post, I haven't had my coffee yet....

Whippet:

If you go to the gallery, or check this thread, you will find examples of what the rendering possibilities are.

Seen the fact that the advanced render plug-ins do not depend on hardware, every computer should return the same result. So, if your renders are too dark, maybe you need a new screen <?>.

Maybe I have an unreasonable expectation of what a light can do.


I finally got to this, but it took 14 different lights placed around the room. Does that seem "normal"?

Whippet:

Nice bathroom :-)

As far as I can see, you don't have a ceiling in your bathroom. Every room has a light source in its ceiling, maybe that would help.

In case you don't have it already, here you can find a library file with lights in several strengths and colours.

Also, keep in mind that the renderers can't handle light falling through glass (or at least have difficulty doing so), and that the colour of the sky has a strong impact on the quantity of light in your model.

Re: Great Program... Many thanks! .....but there are a few questions..
Nice work. But did you try the "Advanced Render" plugin? afaik, that uses the Sunflow renderer. And, yes, to have to use 14 lights does seem excessive.
If not, you couldtry the Kerkythea renderer (www.kerkythea.net) -- it imports .obj files, and even the free version has a quite decent interface. Which should allow you to add textures, and perhaps do some basic UVmapping.
Good luck.

Re: Great Program... Many thanks! .....but there are a few questions..
Thanks for your replies and suggestions. :) I did download the advanced renderer, and that is how I got the extra lights. The ceiling... I don't display the ceilings because they seem to connect oddly to the floor plan and hide the rooms whne I try to position things in 3d view. Is there a way to change how the ceilings connect with the walls? I use different sized walls for what we call hipwalls in the States. I don't know if that affects the ceilings? Do you have to have the ceilings visible to get the light effect?

Sorry about the size of the photo, I just noticed how big it was.

I have Blender, but I am just starting to learn to use it. Is there a way to get my scenes from SH3D to blender to be rendered? I also tried to download Sunflow, but I have no clue how to work it. I'm an old dog. :D How do you get Sunflow to render the scenes from SH3D?

Sorry for the 30 million questions, but I am just kinda feeling my way through this.

But Thanks again for the comments, it's nice to know people like your work.

Re: Great Program... Many thanks! .....but there are a few questions..
Hi Whippetsleek.

Firstly welcome to the Sweet Home forum.

Great looking bathroom and well done on positioning your lights.

I am guessing with you saying you downloaded the light bulbs you have version 1.2 of the BasicPlusExtraLights?

For your 14 lights are you using the Strong bulbs for the most light output?

The problems you describe about the ceiling. Are your walls at different heights, as that does cause a strange ceiling. If not, the easiest way to get your ceiling and floor to match the shape of the walls, after building the walls (which you have done) select the 'Create rooms' then on the plan view, double click anywhere within the closed walls to create a floor and ceiling that matched the contour of the walls.

I think in the future less lights will be required, at the moment light doesn't reflect back off walls or surfaces, so extra light is required to illuminate a scene.

Once you have added a ceiling, as Hans mentioned, you have the option of the bright centre ceiling light (can be both a good and bad thing, depending on the kind of lighting effect required) centre ceiling lights, used by themselves, rarely provide attractive illumination in real life.

Looking forward to seeing your final design! smile

Edit:
PS: Be of good cheer. A model I am working on currently has 35 light bulbs (of varying intensities) 1 fluorescent light (from the furniture list) and 7 room (centre lights) to try and recreate a photo realistic result. It is quite a large area and takes a long time to render but am hoping it is worth it. smile

Re: Great Program... Many thanks! .....but there are a few questions..
LOL Now I do not feel so bad. And yep, I have to disable my ceiling in alot of cases for the lower walls I have for staircases, and hip walls, and such. Hip walls are called because they are at hip height or so, and just used to divide an open concept area, like a living room/ Kitchen combo with no walls. I take my plans and export them to OBJ and then into blender, and then into Autodesk AutoCad,so getting acurate walls are a must or I have to resize them all in Cad.

Here is a bath room that is basically done. I'm having issues with the way my tiles are lining up, but that'll be fixed later. My textures are also going to the white side, but I think that is the effect of the lights?

This is the plan...



This is the 3dview...



and this is the render...




I think I'm finally getting better at the lights. I tried putting some plants into the render, but it wouldn't finish. I'm guessing that the plant textures might be the reason?

Ah I was going to suggest using a box from the furniture list, for your Hip walls, then you could use ceilings for your normal height walls, but since you are going through the export / import process, it might make it more awkward mixing walls and furniture. you still won't have any centre ceiling lights, but how about using a flattered box/es to make your ceiling?

Here is a bath room that is basically done. I'm having issues with the way my tiles are lining up, but that'll be fixed later. My textures are also going to the white side, but I think that is the effect of the lights?
Should the tiles be appearing stretched, or is that what you mean by the issues you are experiencing?.

As for your texture going to the white side (why can I hear Darth Vader when I read this?) it has to be better than the 'dark side!' reaches for Light saber... biggrin
Going to the white side, you mean losing colour, losing textures or appearing on the wrong side of the wall?

I think I'm finally getting better at the lights. I tried putting some plants into the render, but it wouldn't finish. I'm guessing that the plant textures might be the reason?
Unless the plant textures were very large, then not necessarily, there is also an issue (with fix available in next render release) where if an object contains illegal values, then the render won't complete. As a test you could try adjusting just the plants textures to a maximum of 512x512 in a paint/image editing software. Or try other plant/s.

Umm... btw.. where is the edit button? I meant to add that I downloaded both the lights and renderer plug-ins. I'm used to an Infovision board, so I feel kinda two left footed right now. Or maybe as a newbie, I am not allowed to edit? :D
What would you like to edit?

For furniture: Double click (or right click) the furniture in the plan view or furniture list to Modify (and select Modify)
Textures on walls: Select the wall and double click [i[(or right click, choose Modify) Click on the Texture, which opens another window, find your texture again (A step I would like to see removed, if editing the same texture) and choose Modify.

PS: The left click and right click information provided, is while using Sweet Home on Windows, I would imagine a similar mode of operation is available while using Mac OS X (if using a two button mouse) or Linux.

Hope this helps! smile

That is a good idea, I will have to try that...

The tiles are meant to be that way... lol... that is a texture made from the picture from the manufacturer themselves. I was more just commenting on my own poor cropping ability before making it a texture. smile I'll have to crop down the grout lines and make them look smoother and thinner.

As for your texture going to the white side (why can I hear Darth Vader when I read this?) it has to be better than the 'dark side!' reaches for Light saber... biggrin


Hehe.. I was once compared to Leia's adopted mother Breha Organa. Friends said I was like a mini rebellion all by myself, and would bite the ankles of the Emperor on my way pass him to the firing squad... biggrin If that is light or dak... I call it a shade of grey...


But anyway, I was meaning that my furniture was turning white. I'm not sure if it is losing it's texture, or if the renderer thinks the furniture is shiny and is putting a gloss? I'm not sure how to find out.

lol... I was talking about here on this forum. I was looking for an edit button for my post. I see the reply and quote buttons, but no edit. So I was thinking that maybe this forum has a limit on how soon you can edit your posts. I know of forums that have the feature because of too many nuisance posters. I type too quickly sometimes and forget to add things I wanted to say.Either my brain is too fast for the fingers, or too slow... I haven't figured out which yet... wink

Ah so you are using the Uber render, for now until the next release, you may be best using the Advanced render so your textures don't turn white or lose colour.

lol... I was talking about here on this forum. I was looking for an edit button for my post. I see the reply and quote buttons, but no edit.
Once your post has been added and you return to your post, you don't see the edit button, up next to the reply and quote buttons?

Nope, no edit button. I have quick reply, reply, quote, delete, and split, hmmm... is the split post button a sort of edit button? Anyway, no biggie, I'll make do with a bunch of little post.. lol

And yes, I have both the Uber and the advanced renderer , and I hope that is not a problem. I like to use the Uber for final shots, but the advanced is quicker for checking out positions and stuff.

Here is an example of some of my problems...


----------------------------------------


Posted by db4tech at Aug 3, 2010, 9:45:11 PM
Re: Great Program... Many thanks! .....but there are a few questions..
Ah I can see what the problem is.

The lamps are exactly 10 cm wide in Sweet Home, so if you look at your plan view (baring in mind that the wall lights are tapered) you will probably find the bottom of the light is slightly in front of the base of the wall light.

if the wall prevents you moving your light then use the modify button instead, then you can enter a value to move the light further into the wall lamp and slightly inside the wall itself.

db4tech

Or do you mean the bedside tables? If so don't worry, the next release will fix this but for now you may have to use Advanced render to prevent your furniture items losing their colour.

Posted by whippetsleek at Aug 3, 2010, 10:18:11 PM
Re: Great Program... Many thanks! .....but there are a few questions..
The horse statue, the bedside tables, the vases, and a part of the light fixture all lost or misaligned their textures. I installed a RAM cleaner on my system some time ago, so I thought that was the problem, maybe the cleaner was taking away the page file memory or something from SH3d, so I uninstalled it, but that didn't solve the problem, so now I am just reding all of my textures to a new file size, and seeing if that helps with the textures getting mixed.

Re: Great Program... Many thanks! .....but there are a few questions..
BTW, (here would be a good use for an edit button on this thread... smile )

The vases are supposed to be transparent. That I think is a value problem in the mtl file I think?
----------------------------------------


Posted by db4tech at Aug 3, 2010, 11:16:32 PM
Re: Great Program... Many thanks! .....but there are a few questions..
If your textures show fine with Advanced render, then it is the already mentioned problem with the currently available version of Uber.

The render process is being worked on, so don't worry! smile For now just use the Advanced render if you encounter texture colour loss problems.

PS: Yes you can have both render files installed without any problems.

To make your vases transparent, edit your mtl file and enter (below the Ns value of the texture you would like to be transparent)
d 0.2 (or any number less than 1)

I have carried out many, many tests and at the moment Sweet Home only sees either transparent or opaque.

The Kd value controls how light or dark the transparency will be. 1 is normal, less than 1 the object becomes darker.

Extra information for you: Frosted glass, Alpha blending or multiple layered textures aren't an option at the moment.

BTW there is an edit button (if you see my post above) I'm not sure if it only becomes available after x amount of posts or when the user status changes. This is one to ask Emmanuel! smile

Re: Great Program... Many thanks! .....but there are a few questions..
I've just been having to remake everything in blender or AOI. And simplified my texture files so that alot of my furniture all have the same or similar textures. That seems to work the best.

And not having an edit button is all good. *Evil thought* I could try to get the required number of posts.... smile But that would be spam.


My text editor, which is Wordpad, won't let me save mtl files where AOI can read them, it tells me they're missing, so I just retexture everything.. lol, it takes forever the second time around.
----------------------------------------


Posted by db4tech at Aug 5, 2010, 4:44:59 AM
Re: Great Program... Many thanks! .....but there are a few questions..
Wordpad can definitely save mtl files, if is helpful I use it all the time along with Notepad.

I think I know what is happening...

In Windows do you have your Folder view options set so you can see file extensions?
If not, when you edit and save a mtl file, you are actually saving it as .mtl.rtf (or for Notepad it would save as .mtl.txt) but the .rtf (.txt) part will be hidden from you. So you actually think you've saved it as a .mtl but the file won't work because the extension has been changed.

If you are using Windows XP, open any folder and click on the Tools tab.
Then select Folder options...
Click the View tab
Look down the list for Hide extensions for known file types and untick it.
Click OK and you will now see all file extensions.

If using Vista or Windows 7, open any folder.
The tabs are hidden until you press the left Alt on the keyboard. Once the tabs appear then follow the same instructions above.

One of the first things I do, after installing Windows on anyone's machine, is untick the 'Hide extensions for known file types'.


Hopefully this will help save you hours of work! smile

Re: Great Program... Many thanks! .....but there are a few questions..
Oh.. duh. I knew about that, I used to do that a long time ago back when to edit config files you opened them in Winzip and extracted them. It's been a long time since I had to do any file editting, I forgot all about that. That was a aw shucks moment... biggrin

Alot of my models came from 3ds, and I have to convert them into obj or in Google Sketch. I like Sketch, but it's hard to get details, and edit the main wireframe if you need to, so making good mtl files will save some time.

The one thing I can't learn is how to texture just a certain part of a model in AOI when it is a premade model? Do you know? Like say you download a cabinet, and when you load it into AOI, there are no components, just one big wireframe. How do you break down the wireframe to texture just certain parts?

whippetsleek, I added you to Power users group to let you edit your posts and add attachements if needed.

By the way, SunFlow is a program and a library. The library is integrated in Sweet Home 3D and used to render the scenes at the two best levels of the Create Photo dialog, in the Advanced renderer and in the Uber renderer.

Re: Great Program... Many thanks! .....but there are a few questions..
Thank you so very much! I appreciate that alot.

I did read a little more on the Sunflow website, and kind of figured that Sunflow was the renderer for SH3D. That's why I quit asking about it.. smile I know the questions of newbies can be a bit trying sometimes, and I try to learn quickly so that it is not a chore to answer all my questions. You have made an excellent free program, and I recommend it to all the people I know that are interested in design.

BTW, I haven't looked through all the downloads yet, and I unfortunately am not a developer, but is there a way to share texture files as a whole? Like in Google Sketch, you can share your textures with a swatch made from a component.
