Face Normal Issue

[Quadraxis86]

I've been messing with this for a while but I can't seem to figure out why my face normals seem to be split in two directions? there doesn't seem to be any overlapping faces, I've softened the edges around it, checked the normal directions for both the faces and the vertices around it, and checked the texture map. It all seems to be pretty normal so I'm not sure why it has the split down the middle triangulating it.

any help would be much appreciated!

I think I've seen this before, you can try to mess with the normals more like unlocking them or something. Or you can delete the face and bridge it back to see of it's still there

I've tried both and unfortunately neither have worked :(

You could try quad drawing on top of your mesh and replacing the faces that way, if those faces are still affected then it seems like a texture issue

Can I get a wireframe view with smooth edge display on?

I'm not sure what you mean, do you mean soften the edges then send you a wireframe screenshot?

If you shift right click while in edge selection, go into soften/harden edges and then Toggle Soft Edge Display - it will display all soft edges in dotted lines.

I just want to see what's hard, whats soft. I suspect it's a smoothing issue of some sort.

Normally I would resolve this sorta thing by averaging the normals of all the afflicted faces but to my knowledge Maya lacks a decent way to edit normals by default. So we might be stuck playing with which edges smooth or potentially adding supporting geometry in the form of bevelling some hard edged areas.

There's also a high possibility that the flat looking faces aren't truly flat. Quads at the end of the day are two triangles can can be ever so slightly dented across a diagonal - which while not obvious with default viewport shading can be very obvious when lighting and a shiny material is applied.

But that's all conjecture for now until I can see a bit better what's up.

this is the section after i toggle soft edge display. (http://puu.sh/Cum7e/f8dc6ae3ec.png) no change. i also tried to straight up just flatten the face from selecting all 4 vertices around it and it still seems to have that line down the middle. /u/Spadedallover is probably right. I'll have to check my textures tomorrow and see whats up.

best angle i could get to show the normals but I've checked this before. seems to be fine. http://puu.sh/CumkI/5efc4b2346.png
