Well first of all there is no such planet.
Even lush planets without storms, low sentinel activity, and no predators will still drain your life support.
Thats why all my bases look the same in their design. There is always an inside, so I can run around with no life support drain.
There are plenty of such planets though. Finding out if a planet is of this kind can be done easily, too:
- Lush planets have a number of predefined descriptors, such as "Paradise" or "Bountiful", and they have Star Bulb and Paraffinium as resources.
- Non-extreme worlds have regular Copper (regular/yellow stars), Cadmium (red stars), Emeril (green stars) or Indium (blue stars), not Activated Copper/Cadmium/Emeril/Indium. Extreme lush worlds will still have no hazard drain while it doesnt storm but will have storms, more specifically will have extreme storms (I think always ? not sure) and often also Storm Crystals.
- Once you land on the planet, the game will briefly display information about the planet. Specifically it will state the weather and the sentinel activity. If it says something like "Low" for the sentinels, then Sentinels are limited to their specific locations like manufactories, or when you loot something Sentinels protect, such as sentient plants.
- You can also get this information by using the analysis visor without pointing it at anything specific.
- The only sure way I know to find out if a planet has no predators is scanning all fauna. Then again you ususally find out pretty quickly if a planet has predators because you usually get attacked by them very quickly.
So yes, you can find that out pretty quickly and I've seen plenty of these planets. I just dont care that much about them. They only offer very specific resources and I want all types, so I certainly visit all other types of planets as well, and you also cant really build a base without roof on them.
If your graphics card can handle it, you can certainly build bases with tons of glas elements. I have however found that this puts a lot of stress on my (very old) graphics card, so I dont do that.
