| |
| | |
| == Step 1: Choose a model to upload ==
| |
| Second Life accepts COLLADA (.dae) models, which can be edited and created in many popular 3D modeling packages. If you do not currently have any COLLADA models on your computer, you may download some from the [[Mesh/Sample_Content|Sample Content]] page.
| |
| | |
| To begin uploading a model:
| |
| # Choose '''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 '''Name''' field.
| |
| # If your model includes textures, click the {{Icon_Gear|gear icon}} and choose '''Show textures''' to make sure the textures are displayed properly.
| |
| | |
| == Step 2: Define visual levels of detail ==
| |
| [[Image:Low LOD.png|300px|right|thumb|Defining the Low level of detail for an architectural arch.]]
| |
| Levels of detail determine what your model looks like from various distances. As you get farther away from a model, it renders in less detail in order to boost visual performance. Second Life generates these lower levels of detail by default, but you may use this step to tweak each level or even upload your own lower-detail models.
| |
| | |
| The top section of the Level of Detail tab shows how many triangles and vertices your model uses for each level of detail; each level must have fewer vertices than the level above it. To preview your model at each level of detail, choose from the '''Preview''' dropdown above the preview window.
| |
| | |
| While previewing your model at each level of detail, you may change the parameters used for simplifying it from your original model under '''Auto generate'''. For full details on these parameters, see [[Mesh/Upload Model UI reference|Upload Model UI reference]].
| |
| | |
| Alternately, you may upload your own simplified models by choosing '''Load from file'''. You may wish to use your own models in order to preserve critical details that may be lost during automatic simplification.
| |
| | |
| == Step 3: Define the model's physics shape ==
| |
| | |
| == Step 4: Upload the model ==
| |
| === Optional parameters ===
| |
| Before you upload, make sure 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 it is uploaded.
| |
| * '''Include Skin weight:''' Includes any skin weight information in the COLLADA model. You must check this box if you wish to wear your model as a rigged avatar part.
| |
| * '''Include Joint positions:''' Includes joint position information from the COLLADA file.
| |
| * '''Pelvis Z Offset:''' Changes the vertical positioning of a rigged model.
| |
| | |
| === Confirm and upload ===
| |
| Before uploading, you must acknowledge that you possess appropriate rights to the materials contained in your model; check the box at the bottom of the window and click '''Upload'''. Enjoy your new model!
| |
| | |
| == Rigging options ==
| |
| [[Image:Show skin weight.png|300px|right|thumb|Check '''Show skin weight''' to preview how the model will look on an idle avatar.]]
| |
| Rigged models allow you to represent 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 accordingly.
| |
| | |
| If your COLLADA model contains joint position and skin weight information, you can preview how it will look with an avatar's default idle animation by clicking the {{Icon_Gear|Gear Icon}} in the Upload Model window and checking '''Show skin weight'''.
| |
| | |
| === Wearing a model with rigging ===
| |
| You may wear a rigged model by right-clicking it in your inventory and selecting '''Wear'''. You may often wish to pair a rigged model with an alpha mask to hide your avatar's normal shape.
