The following text is from a session on #messiah3d IRC channel.
Lyle showed up and wrote a step by step on how to add Mettaefectors, i took the liberty to edit it and post the info here, wich i believe to be very usefull.
<lmilton> 1. Start messiah
<lmilton> 2. Load an object
<lmilton> Go to Setup->Effects and add a BoneDeform effect to that object
<lmilton> 4. add a few bones
<lmilton> 5. Go to Setup->Tools and add a MetaEffector
<lmilton> 6. Add some Effectors
<lmilton> When you create a MetaEffector, you’re really creating a “toolbox” that will hold Effectors. So, Select the MetaEffector
<lmilton> 7. Select one of the Bones and hit F3 to expand the interface
<lmilton> 8. Click on the Bone tab, then choose the MetaEffector you created from the weight popup.
<lmilton> Ok, we’ve already taken care of the Assignment portion. Now it’s time to take of the drawing.
<lmilton> While you can add an object directly to the weight drawing list, you can have this taken care of automatically when you select bones.
<lmilton> 9. Click on the Skeleton tab and activate: Auto Draw Weights for Targets.
<lmilton> When you select the bone, it will automatically draw the weight on your object.
<lmilton> So, using this feature, the weight drawing will “automatically” change when you select a bone.
<lmilton> This is only compatible with Weight tools, though. The standard bone weighting doesn’t get computed until you leave setup.
<Stoehr> Using connected and all connected falloff options for effectors: Do the connected points have to be seperate object layer, or does it find the points connected, regardless of being in the same object?
<lmilton> All connected will find all those points that are connected. This means that if you have an object that has, say, 2 separate spheres, if you move an effector over one of the spheres, only that sphere will be affectes.
<Stoehr> Does the metaeffector or effector have to be parented to anything in particular? the mesh, bone…?
<Stoehr> So I can parent to anything, it’s just for my convenience.
<Stoehr> very nice.
Hope it helps and be sure to visit #messiah3d.
Thanks for the visit and the info Lyle
