Export your Character as Collada
Hint: You usually can keep the default settings and just click on the “Collada(Avastar)(.dae)” button. A File Selector will pop up. Here you can navigate to your export directory and then export your file as a Collada file (using the file extension “.dae”)
The Export option Subpanels
The Exporter provides a couple of export options for special cases. Please use these options with care.
By default Avastar applies all mesh changing Modifiers except the Armature Modifiers to the exported meshes. However, some modifiers have 2 sets of options, one option set is for rendering, the other option set is for the Viewport. We provide 3 options here:
- Apply according to the View Settings (the 3D Preview settings)
- Apply according to the Render Settings (the settings for Blender’s own Renderer)
- Don’t apply modifiers and only export the base mesh
The View settings will be applied by default. These settings are very closely related to the Blender Render System. In most cases you can actually just use the defaults. We will get back to this when we talk about how to use (or not use) Modifiers.
Armature Modifiers define a relation between your mesh and your Skeleton (Armature). You find the Armature modifier in the Modifer Stack (see image). Armature modifiers are always defined for the mesh. Armatures them self have no Armature modifier.
We will get to armature Modifiers in the “Create an Attachment” tutorial.
Textures export (advanced)
Note: But for rigged meshes the images are not recognized.
- UV Textures & Material Textures: Blender supports Material based textures and UV textures (which are directly assigned to polygons). Normally you want to export only the UV textures. In rare cases it is more desirable to export the material based textures instead. But beware, Blender does not export the render results, but only the source images!
- Image Type: The image format is typically predefined in the Blender Render settings. However we found it convenient to provide an immediate setting in the Exporter. By default the image type will be applied ONLY to generated images.
- Use ‘Image format’ for all images: If this option is set, then Blender will use the selected image format for all exported images. If the option is disabled, then only the generated images will be affected.
- Use RGBA: Blender can export the Alpha channel for images. Normally this is controlled in the render settings where you can specify to use either RGB or RGBA for image exports. If the currently selected export format supports Alpha then enabling RGBA here will export images with Alpha channel even if the render settings are set to RGB and vice versa.
Hint: You may want to NOT use RGBA because of the Alpha glitch. However this is not a general advice. There are many situations where using Alpha images is even recommended (for example when you want to create an Alpha mask).
Hint: If the format of the exported image(es) does not support an Alpha channel then the “Use RGBA” option is simply ignored.
Avastar also provides some advanced export options. However those options are noy shown by defauilt as they are only rarely used.
You enable these options in the Avastar Addon Panel (where you initially enabled the Addon after you installed it):
Limit Weight Count: In SL the number of weights per vertex is strictly limited to 4. We believe this number is sufficient for all weighting tasks. In cases where this limit seems to be too low we always found the real problem was due to bad mesh topology and bad rigging.
Setting this number affects the maximum number of weights which are exported by Avastar. We strongly recommend to keep this number set to 4.
With Attachment Weights: SL does not allow weighting of attachment points. Hence we suppress the export of weights for attachment points by default.
