I made this test animation for an excellent tie fighter from Technouveau Art.   I found the engine and exhaust in blend kit, and added them to the model.  I then select a row of polys in the engine and used blendkit again using the solar sun material. 

THese tips are definitely helpful when modeling.  He takes the time to explain these with good simple explanations.

This is a video showing Mixamo motions and characters in a forest.  The ronin is from The Alive guy Instructor - Pierrick Picaut free to download here.    I wasn't sure how to get his excellently rigged character to receive the mocap, so i think I deleted the armature, used the mixamo website's auto rigger, and used the one of the running animations.  I also used several already mocaped characters and animations from mixamo website.  I added some running sounds.

THis was done in blender for the pwnisher challenge. You can read about this in the endless engine page.
