uhh
or could we just make an image of an idea of a planet instead of having to make an entireplanet ourselves as a mod when I dont have any modding experiece...
yeah I have a new dissgussion and I bet its going to drag me to you about some tecknical stuff because I know C#,but not <insert modding language here>.

and you...
are a modder angel
while Im just a C# worm XD

Modding is done in C#. Logic is created through C# runtime scripts and classes. Blocks and in-game (skyboxes, music, custom blocks) data is altered or created inside XML files. I can assure you I am no modder angel, I know basic concepts derrived mostly from C# in-game programming.
Also, the planets I'm talking about are the ones already on the workshop, I dont expect anyone to go out and make their own planets.

How does the planet temperature actually affect cooling?
I mean, can you use radiators to heat a spacecraft if it is to cold outside or do you need another way of generating heat?
And can you cool a spacecraft to below ambient temperature on a very hot planet?

Radiators will target a safe temperature no matter the ambient temperature. If its cold they'll add heat, if its hot then the opposite.

but what changes then? do you need more radiators the hotter or colder it is or does ambient temperature only the idle temperature of a ship or station?

Ambient temperature will influence the net target temperature that your ship will go towards. The radiator's job is to keep it within functional levels. Simply put, a hotter atmosphere will make it harder to cool down, while a colder one will make it easier. So you may need more radiators if its a hotter atmosphere to compensate for the added heat. The logical inverse is true to cold atmospheres. Remember that each radiator adds more cooling/heating power to control temperature.

Hello maybe you already did it but this giant mod would be awesome to work together with thermal mechanics https://psteamcommunity.yuanyoumao.com/sharedfiles/filedetails/?id=1381037698&searchtext=solar+system i leave the temperatures to you as it will force me to be more creative with the bases XD

dusty desert planet
hot

If you're still taking requests, Ravcor would be awesome.

Ravcor (Another Texture Update)
Quite hot, around 200 Fahrenheit
