That’s everything you need to know about Hard Shelters in Planet Zoo. This will ensure your shelter has three walls, and will make it look a little more natural. You can also try placing a pre-built Hard Shelter down, and then cover it with the Terrain tools. If it isn’t working, try to make the shelter a little bigger. Getting your newly built cave to register as a Hard Shelter can be a little bit tricky. You can check the Environment stat for an animal in the habitat to check that it has registered. As long as your shelter has these elements, and no holes in it other than the main front entrance it will be classed as a Hard Shelter. Also, you’ll need to place bedding inside. First, you will need to make sure you have a defined roof to keep out the rain. While sculpting a cave, there are a few things to consider. You can use this to sculpt a cave shape into the cylinder you’ve formed. Now select the Push function from the list. Place one down in the desired position, we can sculpt it later. Now, select the shaping option, shown in the image below. To do so, select ‘Terrain’ in the bottom right of the screen. You can build your own Hard Shelter using the Terrain tools. This is what the majority of your Hard Shelters will be, essentially caves where your animals can kick back. The latter will look a lot more natural, and you can build it to fit in with the rest of the habitat. There are two ways to go when considering a Hard Shelter: you can buy a premade one, or sculpt one using the Terrain tools. If this is the case, you will see the Hard Shelter requirement in the Environments tab turn red. When too many guests start peeking at them through the glass, or when weather conditions aren’t appropriate, some animals will need a place to hide away and relax. Being housed in a zoo can be a really stressful experience for the animals that live there.
