My sis Tomala has been helping me do certain features and things in Source Filmmaker. I can add new models, lights and other things in the map to make a poster and even publish the artwork of your work on Steam. I can also do face-posing and animations on some characters, resizing their body parts, etc.
Now I can simply enjoy adding sorts of characters and do crazy things to them like making their heads big and even shrink down their hands like what Tomala did to Donald Trump player model. 😛
