Does anyone know what game engine Palworld runs?

[agnos]

I'm tryng using the fmodel for the first time, an error is appearing: "mapping file is missing, can't serialize"... I cant export any psk/psa models, can anyone help me please?

About this, you need to find on internet (github is your friend) or extract your own mappings from the game itself using some stuff to put in the palworld folder (some dll and stuff). 
You will need to set the mappings file in the FModel settings and enable them by checking a checkbox.

I cant do... first time opening visualstudio... dont you have any tutorial video please?
