Game asset workflow

Heavybrush

I would understand better the workflow for a game asset production for now I use to make a 2D concept or directly making the base mesh in maya or zbrush after I sculpt and try to polypaint now... I would understand better what to do to have a final lowpoly handpainted textured game asset I think I must generate the maps, make the retopology before to unwrap the uv and reproject all the high details, but I don't know for sure the order of the things to do

There are hundreds of vidoes that go over this so I'll let them do the talking for me;

A short but sweet tutorial by Warren Marshall that goes over the process of making a manhole cover.

A multi-part tutorials that goes over making a PBR Prop

The basic process is high poly model > low poly model > UV Low poly > Bake High poly details to low Poly > Texture

There's an amazing tutorial series called Environment Creation In Unreal Engine 4. You can find it here:
https://www.uartsy.com/course/environment-creation-in-unreal-engine-4
I believe you can also purchase and download the series online.
It goes through asset creation, preparing for level design, and of course in relation to the thesis of your original post, it goes through the asset workflow or asset pipeline process. I highly recommend it.
