When I scatter my grass object using the free scatter add on within blender, the grass stays static while I roll through my animation. Does anyone know the proper method to attach or parent a scattered object to a mesh so that it stays attached throughout the animation sequence?
The Scatter Object addon will create a series of tris that will stick to the surface of your target object (your character). These tris have Instancing > Faces enabled, with your grass object parented to it. By default these tris are not parented to the surface of your target object. What you can do is parent them to your character. You could also press CtrlA > Make Instances Real and join the grass to the character with CtrlJ.
In the modifier stack make sure that the particle modifier is after (under) the armature modifier.
