Fixing normal angles
on Dec 20, 2011 at 10:55:20 am

Hi all,

I've been working on some IGES files converted to FBX and imported into Maya. I know, it's a recipe for destruction. Either way, I got a decent model now (, but the shading is meh. I'm pretty sure it's a normal angle issue (they aren't flipped), but adjusting the angle for the entire model doesn't fix anything.

In Cinema, one can simply disconnect certain surfaces and that usually fixes odd shading. My question is: does Maya have a similar function? Or, if it doesn't, something else that can fix strange normals?

Hi, Ben. You can select individual edges, and then use the 'Normals > Harden' command to break the smoothing across that edge.

Hope that's what you're looking for. By the way, are you aware that you can adjust the angle threshold when applying the Soften/Harden command to the entire object? You can determine the threshold beyond which the edge counts as 'hard' instead of 'soft.' I'm surprised to hear you say that it isn't useful, that's why I ask.
