Annotation: This is a bones walkthrough of how to upload a model. For full details on the parameters available for uploading a model, encounter Model Upload UI reference.
Update: Viewer version iii.8.ane.303230 modified the mesh importer to (optionally) improve debug output, perform proper name-based LOD association, and handle models with many materials. For additional information on this update, meet the official 2d Life Viewer release notes.
Prerequisites
Before you can upload mesh objects, you must:
- Have payment data on file. Yous can add payment data by visiting the Billing Data section of your Second Life business relationship folio.
- Have accustomed the IP terms on your account page. If yous are planning to use the beta grid (Aditi), you must besides accept the IP terms there, but do not need payment information on file.
- Have at to the lowest degree one compatible COLLADA (.dae) file on your reckoner. Yous can create your own by using nigh popular 3D software packages, or, if y'all have the appropriate rights, you can download models created past other 3D artists from online repositories. Attempt our sample content page for a gratis model if you're but getting started.
You may check your mesh upload status at any time past visiting your account folio on the Second Life website.
Cost to upload
At that place is a Linden dollar fee to upload a model; the fee depends on the model's complication.
GETTING STARTED: Uploading your first model
If you're new to uploading mesh models to 2nd Life, hither's a quick and easy set of instructions to get yous started. Don't worry most the myriad of controls in the upload window for now; they're for Residents who want fine command over their model'southward advent and physics. For a more detailed breakdown of the upload procedure, proceed reading below.
To upload a mesh model:
- Choose a .dae file stored on your calculator by choosing Build > Upload > Model. If you don't have any models on your computer, you may download some from the sample content folio.
- Preview your model's automatically generated levels of particular on the Level of Particular tab by clicking High, Medium, Depression, and Lowest. Notice how the object's complexity is reduced at each level.
- Click the Physics tab and choose Lowest from the dropdown bill of fare in Stride i: Level of Detail. Step 2 and Step 3 are not required.
- Click the Upload options tab and cheque the boxes for any boosted features on your model, such equally textures.
- Click Summate weights & fee, then review the resources weights, land impact, and Linden dollar upload cost of your model.
- Click Upload to upload your model to Second Life.
Tip: To avoid spending Linden dollars while experimenting with uploading models, you may wish to apply the 2d Life Beta Filigree (Aditi). The Beta Filigree allows you to test new features and experiment with potentially costly designs in a prophylactic environment, using a copy of your Second Life business relationship. Deportment taken on the preview grid cannot touch your inventory or L$ remainder on Second Life's master grid.
Step 1: Choose a model to upload
Second Life accepts COLLADA (.dae) models, which can be edited and created in many pop 3D modeling packages. If you lot do not currently have any COLLADA models on your reckoner, you may download some from the sample content page.
To begin uploading a model:
- Cull Build > Upload > Model...
- Select the .dae file on your computer and click Open.
- In the Upload Model window, enter a suitable name for your model in the Model proper noun field.
- If your model includes textures, bank check the Textures box underneath the Preview pane to brand sure the textures are displayed properly.
Pace 2: Define visual levels of detail
Levels of detail determine what your model looks like from diverse distances. As you become farther away from a model, information technology renders in less detail to boost visual functioning. Second Life generates these lower particular models past default, but you lot may use this footstep to tweak each level or even upload your own lower item models. You tin preview your model at any level of item by clicking High, Medium, Depression, or Lowest.
While previewing your model at each level of detail, you may alter the parameters used for simplifying it from your original model if you choseGenerate from ane of the Source dropdown menus. For full details on Triangle Limit and Error Threshold, see Upload Model UI reference.
Uploading your ain LOD files
You lot may upload your own simplified models past choosing Load from file from the Source dropdown menus. You may wish to create your own lower-detail models in order to preserve critical details that may be lost during the automatic simplification process.
The mesh uploader uses very strict naming rules for these custom LOD files:
- File names ending with "_LOD2" must exist used for Medium level of item
- File names ending with "_LOD1" must be used for Low level of detail
- File names ending with "_LOD0" must be used for Lowest level of detail
- File names ending with "_PHYS" must be used for the model's physics shape
Additionally, material names must matchexactly between each level of detail. Some 3D modeling programs such every bit Blender automatically alter cloth names to preclude duplication when multiple versions of a model are loaded into the same scene.
Material names are sorted alphabetically upon importing a model from the 3D modeling program of your choice, and may not retain the club they had in the original model. If textile social club is important to your model, y'all must name them accordingly.
For more detailed information on uploading mesh models with multiple materials, meet Uploading a multi-face up mesh on the 2d Life Wiki.
Note: If yous need to upload an onetime model that does not conform to these LOD naming rules, you may enable the debug setting calledImporterLegacyMatching in the 2d Life Viewer. Access the Debug Settings window by choosingAdvanced > Debug Settings from the top menu bar.
Step iii: Ascertain the model's physics shape
A model'southward physical shape, as interpreted by Second Life'south physics engine for computing collisions, can be different from its visual shape. For instance, yous may wish to simplify a very circuitous vehicle into a square physical box shape, which allows you to accept a visually complex vehicle that requires insufficiently little physics computation and does non overtax the region's ability to process moving physical objects. Y'all may upload your own physics representation as a .dae file or y'all may use 2nd Life's analysis and simplification tools to generate a physics shape automatically.
The quickest style to generate a physics model for your object is to choose Use Level of Detail and select a level of detail from the dropdown carte du jour. This creates a physics model based on one of your model'southward visual levels of detail. Remember that lower physics costs are desirable, and so choose the lowest level of particular that reasonably represents the shape of your model.
You do not demand to consummate Stride 2: Analyze or Step iii: Simplifiy unless your physics model is extremely complex or shows red lines in the preview window. For advanced data on usage of the physics analysis and simplification tools, see Upload Model UI reference.
Step 4: Upload options
Before you upload, make certain to include any necessary optional parameters on the Modifiers tab:
- Scale: Changes the base size of your model. Increasing the scale increases the resource cost.
- Include Textures: Includes any textures applied to the COLLADA model. The textures are automatically applied to the Second Life version of the model when information technology is uploaded.
- Include Skin weight: Includes any peel weight data in the COLLADA model. This option just applies to models that are meant to move and flex with your avatar when worn equally avatar attachments.
- Include Articulation positions: Includes joint position data from the COLLADA file. This selection just applies to models that are meant to alter an avatar's joint positions when worn as an zipper.
- Pelvis Z Offset: Changes the vertical positioning of a rigged model.
Step five: Calculate weights & fee
When you click Calculate weights & fee, Second Life calculates the download, physics and server weights of your model in order to decide its land bear on and Linden dollar upload cost. The base Linden dollar cost to upload is L$ten plus Fifty$10 for each texture applied to the model, and an boosted cost based on the complexity of the model.
For more than information well-nigh weights and land impact, encounter Calculcating state bear on.
Step 6: Upload
When you upload a model, it appears in the Objects folder in your inventory. Equally with all objects in 2nd Life, you can then drag information technology from your inventory to the footing, or yous can wear information technology as an attachment.
Bonus department: Rigging options
Rigged models allow you to correspond your avatar skeleton as a mesh that conforms to your joints and motions. This means that you can wear a rigged model that changes the length and orientation of your avatar's limbs and animates appropriately.
If your COLLADA model contains joint position and skin weight information, you tin can preview how it will wait with an avatar's default idle animation by checking thePare weights box underneath the Preview pane.
Wearing a model with rigging
You lot may wear a rigged model by right-clicking it in your inventory and selecting Wear. You lot may often wish to pair a rigged model with an blastoff mask to hibernate your avatar'south normal shape.
