I have a hair object, and I wonder how it was done.

enter image description here

Is this hair composed by planes? And if yes, are they double-sided? To me it looks double-sided because it is also visible from the other side.

I have also uploaded the project here if somebody needs to take a closer look.

Thank you very much!

  • yes it is made out of planes. Read my answer here to see if it is double sided. – David Jun 25 '15 at 14:37
  • By default blender shows the backsides of single-sided faces. To make faces double sided, enable Double Sided in Properties > Object Data (see http://blender.stackexchange.com/q/9049/599). – gandalf3 Jun 25 '15 at 17:56

No they are not double sided. You can check this by going to the N menu and checking Backface Culling under Shading options.

  • So you mean that these are just simple single-sided planes? You did not really refer to whether these are planes or not. – tmighty Jun 25 '15 at 14:39
  • Yes, that is the default for Blender – J Sargent Jun 25 '15 at 14:40

  • Do you think you spot anything unusual with the planes or how they were created? I am asking because when I add a new plane and export my new mesh to a game engine (Unity in this case), this plane does not pick up a material and stays untextured while the other planes are textured. – tmighty Jun 25 '15 at 14:48
  • Part of the same mesh? – J Sargent Jun 25 '15 at 14:49
  • Yes, they are part of the same mesh. I have even added some between the original planes to see if the location plays a role, but it does not. The only difference that I see is that my planes are quads, and the original planes are tris. – tmighty Jun 25 '15 at 14:52
  • No, it wouldn't. Planes are single-sided by default in Blender – J Sargent Jun 25 '15 at 14:54
  • I wanted to say that my planes have 4 edges, and the original ones have 3 edges. – tmighty Jun 25 '15 at 14:55
  • That doesn't have an effect either. You have to manually make them double sided – J Sargent Jun 25 '15 at 14:55
  • Sorry I have not enough reputation for a chat, so I am asking here: You said that they are not double-sided, so I am a little confused why you talk about double-sided again. I have even converted them to tris using Ctrl+T, but that didn't make any difference either. Do you still have any idea why my planes would not take up a material? I am not sure what the difference between my planes and the original planes are. Do you still have any more idea? – tmighty Jun 25 '15 at 15:01
  • @tmighty Do you not want them double sided? They aren't so if that is what you want you are good to go – J Sargent Jun 25 '15 at 15:13
  • Nope, I was just hoping you would spot anything unusual about the original planes. – tmighty Jun 25 '15 at 15:14
  • Everything I see is completely normal :) – J Sargent Jun 25 '15 at 15:24
  • One last thing: In an fbx viewer, I can see that my new planes do not reflect the light as the original ones do: http://s23.postimg.org/vobzvc0qz/light1.jpg Isn't this weird? – tmighty Jun 25 '15 at 16:51

    Is the same material applied and are they UV unwrapped? – J Sargent Jun 25 '15 at 16:53
