Agenda

1. Can Linden provide any feedback/knowledge concerning a method of mesh clothing upload which circumvents the use of the existing mesh clothing deformer yet provides similar (if not the same) functionality? For background, a known full-perm clothing merchant recently made available an article of clothing which conforms to changes in av slider values. ( http://www.youtube.com/watch?v=POwQE10sxGg&feature=player_embedded )They claim the item does not use Qarl's mesh clothing deformer but decline to discuss the method being used behind the object creation. Speculation is that a hack is being done to .dae files in order to get this to work. If this is the case, is this a method of content creation which designers should or should not make use of at this time? Aki Shichiroji
2. Any mesh item must provide 21 dedicated bone weight groups (see below), otherwise the SL Importer does not accept the item. However these weight groups can be empty. What is the reason for having this constraint? If this constraint does not exist, then where can i find an example .dae file which shows how to import a mesh with less than the following list of bone weight groups ?
   • mHead, mNeck, mCollarRight, mCollarLeft, mShoulderRight, mShoulderLeft
   • mElbowRight, mElbowLeft, mWristRight, mWristLeft, mChest, mTorso
   • mPelvis, mHipRight, mHipLeft, mKneeRight, mKneeLeft
   • mAnkleRight, mAnkleLeft, mFootRight, mFootLeft

3. For Mesh items with textures the SL Importer sometimes does not recognize the textures. In particular when a mesh contains weights and "weights" is enabled in the previewer, then the textures disappear instantly in the preview window and they do not get uploaded. Is this on purpose or is this a bug ? If this is not a bug but a wrong collada input, then where can i find an example .dae that allows to import textures along with a rigged mesh.

4. I found that the SL Importer recognizes a rigged mesh by checking for a <controller> node in the collada file. It does not care about the scene description in that case. This implies that if we provide a full scene description that does no harm to the import. Is this correct ? Gaia Clary 01:56, 25 June 2012 (PDT)
