I present to you Chell from Portal 2. She really really loves testing! If you ask her a question she will respond by jumping. She might have a minor case of permanent brain damage because she has been in stasis for so long. With her trusty 'Aperture Science Hand Held Portal Device' she is ready to solve any test chamber you put her in!

This Lora has p2chell, p2cube, p2turret as tags. (for Chell, a cube or a turret).
Should work with most checkpoints. I used Photon in my examples. Clip Skip 2. At 0.8 or 1.

I used Garry's Mod and played Portal 2 to get most of the images I wanted, such as multiple angles of the cubes, test chambers and the portals on the wall. Tried to keep that uncanny 3D look she has, but then things started to get really interesting at epoch 14. The portals on the wall actually looked really good in some generations showing other test chambers, and Chell effortlessly stepping through them :). I was happy! haha.

Hope you like it!
