Hi this is a motorcycle i've been working on for my portfolio and I'm making a low poly out of it. I'm new in game modeling and it'll be really thankful if you give me some tips.
I learned that when making a low poly, it's much better to incorporate each part into one combined mesh as tightly as possible, but not the nurnies like bolts and stuff? So I'm gonna make low poly of small and repetitive objects separately and overlap their UVs with each other to save texture space. (Correct me if I'm wrong)
Anyway my question is, after finishing low poly and when mapping UVs of combined mutiple objects like this bike, should I lay out all the UVs into a single map? Or use multiple maps? I'm curious because the model consists of various materials like shiny/matte metals, leathers, plastics, rubbers etc and if this is for image rendering I'd make texture individually for each material. But this is for games so.. how do you do it?
Oh and this model is for hero asset of AAA TPP game and gonna be imported into UE.
Bear with me, English is my second language.
