Regular Map (Maelstrom) Tundra PvE
Breeding Area (Top Floor)
1. Two story (4 walls high) w vaulted ceilings. Top floor was breed area. Also I suggest building it 2-3 foundations above ground level so snakes can't glitch through the wall. Quick and dirty way is to make all inner foundations thatch and wrap it in wood. Stone IS NOT necessary.
2. One tile in from the outer wall I placed wooden doorframes on 3 sides of the 2nd floor.
3. Between the outer wall and inner perimeter doorframes I placed as many campfires as i could fit
4. I left enough room on the entry wall for a preservation bag w ice, a water barrel and large storage box for saddles and various crap.
5. Used a small gate w ramps for entry. Whole breeding area was about 8x6 tiles, maybe? Plus about 8x6 for the conga line outside.
6. I was able to place the stud in the middle w a female on each side and breed 2 at a time. As my stable of female lions grew (~20) I would line them up towards the entry in a conga line and rotate until i got to the first one impregnated. This resulted in ~2 births every 3-5 minutes to give ample sorting time.
*** Very Important Bottom Floor ***
1. Raised the floor 2 foundations using foundations in the center, ceiling tiles on the edge and added half stairs.
2. Crawled around and spread ~6 campfires AROUND THE CENTER DIRECTLY UNDER the mating area. I usually only needed the center 4 or so. Leave space to crawl between to light them and refill.
3. When built correctly the campfires from the bottom floor will be ~touching the bottom of the second floor. In real life it would burn down , but, in Atlas the heat from the campfires underneath radiates safely to the 2nd floor breeding area.
Few pro tips
A. However much raw meat you think you'll need, triple it.
B. Park Bears away from the feeding troughs or they'll eat the meat for the maturing lions.
C. Lots of ice and preserving bags
D. I used salted meat in the feed troughs since it lasts 8 times longer than raw.
E. If your doing this for resale most buyers will want tigers for the swipe and bleed.
F. Don't freak out about the hot and cold icons above the new borns, just check their HPs, usually they'll be fine when you get practice. At night the temperature drops so I would often get cold icons but they rarely lost more than 2HPs out of 35 and immediately healed when the temperature returned to normal.
G. Once I had my litter sorted i drug them to the corner and usually operated w 4 1st floor campfires and ~7 2nd story fires.
H. Don't forget to disable wandering, follow, actiivate ignore group whistles and set them to passive.
I. Occasionally, in addition to all the aforementioned campfires, I had to use ~8 torches on a switch, placed on the doorframes, to get breeding to occur. Cold front maybe?
Final thing, this system is 2+months old.
Good luck.
