Non planar faces

Hello, Im kinda new on 3d modelling. I couldnt figure out if theres a problem having non planars on a char model.
Is it ok?
I know that the model will be triangulated on the engine importer(or blender exporter idk). But is there any problem having some non planar faces(just a few)?

Sorry for my poorly written english(and for the noob question as well:yes:)… Im not english native speaker.

But is there any problem having some non planar faces(just a few)?
On a character model I’d expect the vast majority of faces to be non planar. Does it look OK ? That’s the most important thing

if it’s too bent, it can be a problem, because you don’t really know which direction it’s going to be triangulated in, so it’s kind of like rolling dice.

It looks(almost) ok. Just some quite unnoticeable difference in how light “touches” those faces.

Using “split non planar” it was splited right. But i was trying to make it just planar quads
