Car and there engines
I want to ask, when create a car, and cars have engine, do i have to also create all the internal workings of that V8, V6 model the pistons crankshafts ect, or just model just a solid engine with nothing inside? i need to know for Blender2.82 thank you.
I'm no expert on 3D modeling, but I would never create something people are never going to see, go with nothing inside & save the polys for stuff that they can
A working internal engine is certainly not a requirement for GTA V, we don't even have moving driveshaft etc.
Also, to get stuff into GTA V, I suggest you get yourself acquainted with ZModeler 3, afaik that is a requirement (for vehicles anyway).
