How do you model a character for a game with Customizable parts

Styrwirld · Sep 2016

Hello, so I am working in a game that will have customizable characters, semi realistic features.

So my question is how do you model them so you can switch eye types, nose, mouths, how do normal maps work here?

is there any tut?

Thanks in advance.

Yes I did, is this the same method used for example on tera? or Black Desert online? Blade and souls?

Mostly, yes. Though I don't think Jesse used morphs in his Mutant League. For facial tweaking, like adjusting nose width etc., a good way to handle that is by using morph targets (Maya: blendshapes).

Another technique, which he outlined a bit at the end, is to use texture channels to create masks where the user can adjust the colors of different parts.

How about normal map blendshapes? how do you bake/use those?

Blendshapes in a game typically re-use the vertex normals from the base mesh. So you would bake the maps using the start blendshape as your lowpoly target. And just sculpt whatever offsets you want... forehead wrinkles, frown creases, etc.

At least that's how I'd approach it. I've done some game morphing but not exactly for customizable characters. Try some tests and see what you get, refine, rinse, & repeat.
