Question - Adding Prop/Mesh to Model 3Ds/Blender

[WyvernX1]

Hi there community,

 

is there any kind of tutorial over there or somewhere that shows you how to add Parts/Objects/Stuff to already existing model, be it Human or animal ?

i talking exactly about Animal "Stuff" models

i know how to "Blender" an Model in Blender (get it ? )

but i need to know how to attach it to the model and do all that stuff to make it working in Skyrim

 

i would like to know exact thing like Blender version + Tools requirement

and step by step tutorial ( video tutorial could be too )

(prefer blender but if there is 3ds max also and if it's easier than Blender why not)

i will surely share my creations then, thanks
