Re: Im an idiot when it comes to mirroring objects.
Usually when I mirror an object I use the Mirror Geometry! If I can, I place it so I can mirror it directly over the axis but with an offset, so that when I put the mirroring pivot at zero, the object will be seperated (visually - they're still a combined mesh though).. Also I find that it works better to select all faces… -
Im an idiot when it comes to mirroring objects.
EDIT: Erased original question because it was convoluted and basically not describing my problem. The Problem: Mirrored objects are behaving strangely with applied normal maps. No amount of freezing, reversing normals, changing render stats is getting them to display correctly. Not sure what going on. -
Re: Im an idiot when it comes to mirroring objects.
It's a simple fix. After mirroring your object, freeze transforms. Still in object mode, do a normals > reverse. Hit control+A for attributes (might have to hit it a couple of times) until you see a tab marked "render stats" and expand it. Uncheck the box marked "opposite". You're done. -
Re: Im an idiot when it comes to mirroring objects.
There is actually something unusual about the way Maya handles UVs which may be causing your problem. Maya uses the UV winding order to determine which way UVs "face". This is not an issue in game engines because they don't calculate it this odd way. If this is your issue then it's purely a maya viewport issue regarding… -
Re: Im an idiot when it comes to mirroring objects.
So the two pieces of geometry here share the same normal map, and same uv space, just mirrored. The one on the left is the original, the one on the right is new. When combined they both look great, the moment I separate them the one on the right get distorted, as if the green channel is flipped. If I recombine them, poof,… -
Re: Im an idiot when it comes to mirroring objects.
CheeseOnToast, Bal - Yup, thats what I usually, always do...never fails, and then all of sudden nothing is working lately. Im starting to think my issue is hardware related and it just spun me out... Ill test everything again this afternoon and see what happens. Thanks guys -
Re: Im an idiot when it comes to mirroring objects.
Yeah most of the time to uncheck "Opposite" you have to uncheck "Double Sided" first if it's checked, you can then check it again. I really don't understand why Maya still does this, it's pretty stupid and messes with so many beginners. -
Re: Im an idiot when it comes to mirroring objects.
Heres an example using Mesh-> Mirror Geometry, which is producing a very similar effect. Also, I dont usually use this because of the way it mirrors and combines the end product. I also miss the ability to place the pivot as the axis to mirror off of. And if I recombine them, the visual issue with the normals goes away? So… -
Re: Im an idiot when it comes to mirroring objects.
The fix described by CheeseOnToast/Bai will also fix meshes mirrored by doing the inverse scale thing. I prefer to use inverse scale on an instance duplicate because it means I can preview the mirrored result and have it update while I work on one half. -
