I noticed when using a “plane,” for example, one side will be renderable but the other side will not. I want both sides of the plane to be seen/renderable in a 3D application. I’ve tried things such as duplicating, then rotating, then merging each vertex, but only one side is rendered. Anyone know a way to do this? Thanks in advance.
That’s only true of UVMapped images in the GameEngine. Hit F to goto UVFaceSelect and Click “TwoSide” in the Texture Face buttons then “Copy Drawmode”.

Still doesn’t work. 
Here’s an illustration for further specification.
For the record, I export these models to .OBJ’s.
did you try duplicating then flipping normals?
this other application should have an option to make faces two sided
Yeah, I did do the duplicating and flipping normals thing. It works, but I could have sworn there was a more efficient way to do this in Blender.
Quick example:

If it doesn’t work on the Irrlicht side then the problem is either in the exporter or the app you’re using.

Yeah, you’re right, it’s something wrong with the irrlicht loader. I guess I’ll just have to duplicate and invert the normals.
But how did you do the 2 sided object/UV in that .blend file? That’s pretty cool. 
From my previous post:
Hit F to goto UVFaceSelect and Click “TwoSide” in the Texture Face buttons then “Copy Drawmode”.

Heh, I’ll see what I can do. Well, thanks for all the help.
