I have finished the Powerloader, a walk cycle for it, poses for the Pilot, some anims for the pilot getting in and out of it, and two texture maps.
I have also built the inside of the Sulaco spaceship for a scene, and I am busy converting and texturing the dropship, APC, Sulaco, all the rifles and alien extras from the Movie Mesh site:

(I have altered the dropship and APC so that the doors open and wheels turn and turrets rotate, etc. There will be two versions of the dropship, one on normal poser scale, and one on a smaller scale to do exterior scenes with the Sulaco spaceship, which is too large to use in normal Poser scale.)

I have also made two walk cycles for the free alien creature from Props Guild:

I am busy negotiating with D Proctor about where and how to host the freebies. Not sure yet, but I think there will be a button on his site for the Poser versions that will connect to the site where I will host all the freebies. Working on it now, but might take me a while.

When all is ready there will be about forty freebies for the Alien project, including a *.wav file and vocal anim for the pilot, textures that match the movie clothes and hair, various anim files, and many add-on sci-fi props to populate the scene (crates, boxes, barrels, etc.)

Will post here when all is ready.
