Dear Agony Aunts,
Are my normals normal?
I'm worried that my normals may be abnormal, and that this may adversely affect my chances. I know this sweet little Fairy, and I'm trying to make some butterfly wings for her, but my normals don't look normal, and I'm worried that she will reject the wings, and me along with them. Dear Agony Aunt, can you suggest something to help me please?
This is a flat two-sided rectangle, and has groups for left and right sides. It has one material zone, with the mapping on the back side being a mirror of that on the front.
In the image both wings have been morphed so that they bend forwards (see outline view). The left wing (your right) looks like it is bending backwards, but it's not, it's bending forwards like the right wing. This looks like a classic case of reversed normals, right? But is it? If I import another instance of the prop with flipped normals the problem should change to the opposite side, yes? Here is the really weird part, it doesn't, it looks exactly the same as the un-flipped version :huh:! So perhaps it's not flipped normals causing the problem. But if it's not flipped normals what can it possibly be? :blink:
The problem only seems to be in preview, a rendered image looks OK. Is there any acid test to determine if the normals are actually facing out or not?
Dear Agony Aunts, I'm hoping you can suggest a way to fix the wings, so my Fairy won't forsake me.
P.S.
If that's not possible, I wonder if you could please recommend some quick acting poison? :sad:
P.P.S.
I'm using P6, and there is a transparency map applied to the prop.
