Blender How to Lower Avatar Complexity for Second Life Upload
Before you can upload mesh objects, you lot must:
Yous may bank check your mesh upload condition at any time by visiting your account page on the Second Life website.
If you lot're new to uploading mesh models to Second Life, hither'southward a quick and easy set up of instructions to become y'all started. Don't worry about the myriad of controls in the upload window for now; they're for those who want fine control over their model'south appearance and physics. For a more detailed breakdown of the upload procedure, keep reading below.
To upload a mesh model:
Step 1: Choose a Model to Upload
2d Life accepts COLLADA (.dae) models, which can be edited and created in many popular 3D modeling packages.
To begin uploading a model:
Step 2: Define Visual Levels of Detail
Levels of detail decide what your model looks like from various distances. Every bit you get farther abroad from a model, information technology renders in less detail to boost visual performance. Second Life generates these lower detail models by default, just you may utilize this step to tweak each level or even upload your own lower detail models. You can preview your model at any level of particular by clicking High, Medium, Low, 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 yous chose Generate from ane of the Source dropdown menus. For full details on Triangle Limit and Fault Threshold, see Upload Model UI reference on the SL Wiki.
Alternately, you may upload your ain simplified models by choosing Load from file from the Source dropdown menus. You lot may wish to create your own lower-detail models in order to preserve critical details that may be lost during the automatic simplification procedure.

It is highly recommended that you read these two blog post for information on best practices:
Step iii: Define the Model's Physics Shape
A model's physical shape, equally interpreted by Second Life's physics engine for calculating collisions, can exist unlike from its visual shape. For example, you may wish to simplify a very complex vehicle into a square physical box shape, which allows yous to have a visually complex vehicle that requires comparatively little physics computation and does non overtax the region'south ability to process moving concrete objects. Y'all may upload your ain physics representation every bit a .dae file or you may apply Second Life's analysis and simplification tools to generate a physics shape automatically.
The quickest way 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. This creates a physics model based on 1 of your model's visual levels of detail. Remember that lower physics costs are desirable, and then cull the lowest level of detail that reasonably represents the shape of your model.
You do not need to complete Footstep two: Analyze or Step 3: Simplifiy unless your physics model is extremely circuitous or shows red lines in the preview window. For advanced information on usage of the physics analysis and simplification tools, encounter Upload Model UI reference.
For more, come across Mesh Upload - Physics
Footstep 4: Upload Options
Before you lot upload, brand sure to include any necessary optional parameters on the Upload Options tab:

Pace v: Summate Weights & Fee
When you lot click Calculate weights & fee, Second Life calculates the download, physics and server weights of your model in order to determine its land affect and Linden dollar upload price. The base of operations Linden dollar cost to upload is Fifty$10 plus Fifty$10 for each texture applied to the model, and an additional cost based on the complication of the model.
Step 6: Upload
When you upload a model, it appears in the Objects binder in your inventory. As with all objects in 2nd Life, you can so drag it from your inventory to the footing, or you tin can clothing it as an attachment.
Rigged models allow you to stand for your avatar skeleton every bit a mesh that conforms to your joints and motions. This means that y'all can wear a rigged model that changes the length and orientation of your avatar's limbs and animates appropriately.
If your COLLADA model contains articulation position and skin weight information, y'all tin preview how it volition look with an avatar'south default idle animation by checking the Skin weights box underneath the Preview pane.
You may wear a rigged model by right-clicking it in your inventory and selecting Clothing. Y'all may oft wish to pair a rigged model with an blastoff mask to hide your avatar'southward normal shape.
