I was using the negitive gravity well and I didn't realise how hot the core was, It's cool to watch it for you want to know what happens. Just use the NEG GRAV WELL in the center of the core
ima tell you the steps to make a REAL planet! step 0 (opional): copy off another planet, melt it then wait for it to cool. step 1: make gravity settings radical. step 2: put in random powders and soilds, no water. step 3: heat it up, best melting point is 4000c. step 4 (opional): equip MIX or WIND to mix, best to use walls to contain the flying lava if your usin WIND. step 5: wait to cool, do not use COOL to speed up the process if you want a lifefilled planet, step 6: yay
planet made by humans but its extremely destructive
