Uploading your mesh .dae files to you second life account step by step

1) To upload mesh content you must payment information on file : Billing Information
2) To upload mesh content you must complete the mesh tutorial : Mesh Tutorial for the Main Grid
3) You need a mesh enabled viewer such as Second life viewer or Singularity
4) In you SL viewer go to Build > Upload > Model.
5) A window will open allowing you to select a .dae files from your computer
6) first tab "level of details" LOD

LOD = Level of Detail

What is LOD?

LOD is the viewing distance at which the detail levels change. It means that the detail of your object reduces the more you zoom out from it. This is defined by the number of triangles and verticals of an object.

The LOD can be auto-generated or you can create new .dae files with less verticals yourself. The ones you create yourself are usually better quality but more work of course.

If you click on High, Medium, Low, and Lowest on the left side of the tab you will be able to visualize how your object looks with the chosen number of verticals. Notice how the object's complexity is reduced at each level.

For more information on LOD check this wiki poste :

LOD tab settings

If you have made your own .dae LOD files you can use drop down menu to choose "Load from file" and select your .dae LOD file

If not you can try these settings :
- High > your object .dae file
- Medium > Load from above
- Low > I usually reduce this level (except for clothes and buildings)
- Lowest > for furniture you can put this level to 0 (not for clothes and buildings)

Then you can clic on calculate weights and fees. The LOD will change the weight and fees each time you modify them. Each time you change it you have to recalculate, you can play with the settings until you find a price/weight that is acceptable for you. Keep in mind that the physics tab will also make a difference on weight and fees.

7) "Physics" tab

What is physics? (or collision file)

Wiki has quite a detailed post on physics :

Basically it means what will happen when you interact with the object, when you walk into it, sit on it, stand on it, its what makes your object hard. This is mostly important for furniture and house parts that need openings ect... but for all the other objects the lower the physics the less prims it will use (generally speaking because it is not an exact science at all).

The same applies here as for the LOD, physics can be auto-generated or you can create .dae files with less verticals and more precise yourself. The ones you create yourself are usually better quality but more work.

Phisics tab

Step 1 : Level of detail

> Choose from the drop down menu that says "choose one"
The choices are high, medium, low, lowest, from file.

When you have chosen one of these options you will see that your item in preview window is highlighted in yellow. This shows you what how the physics will behave with the chosen option.

Each option combinations will give you different results that i will not go into in this tuto.

I will just give you a few examples of settings that i use regularly. The best way will be what works for you but you can try these out :

For avatar attachments and dead objects like lamps, clocks, vase :
Step 1 : low or lowest (sometimes it doesn't accept low)
Step 2 : Analyze
Step 3 : From method menu choose "retain %" put retain N° to 1 then click simplify

For house parts what need to have a hole in for example or furniture you need to sit on.
Step 1 : High
Step 2 : Analyze
Step 3 : From method menu choose "retain %" play with N° then click simplify, each time you will see the result change in the preview menu, find the best option that works with your object.

Upload options Tab :

Here you can check the size/scale of your item. Sometimes when exporting we do not pay attention to scale so this is a very useful tool. Adjust the scale if necessary to obtain the right dimensions.

Otherwise this Tab is exclusively for rigged items such as clothes and avatars.
If you item is rigged simply check the the "include skin weight" option.
Joints are not usually necessary unless you know otherwise.

Finishing upload :

When all the steps are complete
> Name your object
> Choose what it represents although i'm not sure that actually dose anything.
> Calculate weights and fee and wait for price and details to show
> Upload


Watch the details at the bottom of the window under the calculate weights and fee tab :

Each time you change an option it will affect the land impact, physics and fees. Remember to calculate and check as you change things to help find the best combination.

To see the physics of your objects inworld : How can i see physics
> Show advanced menu :
Windows - Ctrl+Alt+D
Mac - Ctrl+Opt ⌥+D
Linux - Ctrl+Alt+D
> Choose Advanced menu > Show Develop Menu to enable it.
> Go to Render Metadata > Physics Shapes

When you upload furniture or houses : My physics are not working
By default you object is physics shape is set to "Convex Hull", in order to use the physics settings you chose, you must change this to "Prim". This can also change the prim count.

My upload .dae file is making me crash
Sometimes your viewer will decide it dose not like a file, changing the name of the file each time before uploading is a workaround that often helps.
