To use Poser or not?  I bought Poser but have yet to educate myself save the online freebie tutorials.  Before I spend a great deal of time, I wonder if I might ask a noob question. 

My wish is to create short animated films (3-8 minutes).  I can't draw.  I was hoping to buy precomposed figures, props, etc.  Many I see for sale look fine for my needs.  But, quite often I will need to tweak the prop.  Is it possible to edit a bought prop?  For instance, I need a haunted house with working window shutters.  The buildings for sell don't have shutters.  I'm sure I can create a shutter.  I just wonder if it is possible to add these to the bought model?

Thanks in advance.
